Functions

func AddOptionEntriesLibgtkOnly

func AddOptionEntriesLibgtkOnly(group *glib.OptionGroup)

AddOptionEntriesLibgtkOnly appends gdk option entries to the passed in option group. This is not public API and must not be used by applications.

Deprecated: This symbol was never meant to be used outside of GTK+.

The function takes the following parameters:

• group: option group.

func Beep

func Beep()

Beep emits a short beep on the default display.

func CairoCreate

func CairoCreate(window Windower) *cairo.Context

CairoCreate creates a Cairo context for drawing to window.

Note that calling cairo_reset_clip() on the resulting #cairo_t will produce undefined results, so avoid it at all costs.

Typically, this function is used to draw on a Window out of the paint cycle of the toolkit; this should be avoided, as it breaks various assumptions and optimizations.

If you are drawing on a native Window in response to a GDK_EXPOSE event you should use gdk_window_begin_draw_frame() and gdk_drawing_context_get_cairo_context() instead. GTK will automatically do this for you when drawing a widget.

Deprecated: Use gdk_window_begin_draw_frame() and gdk_drawing_context_get_cairo_context() instead.

The function takes the following parameters:

• window: Window.

The function returns the following values:

• context: newly created Cairo context. Free with cairo_destroy() when you are done drawing.

func CairoDrawFromGL

func CairoDrawFromGL(cr *cairo.Context, window Windower, source, sourceType, bufferScale, x, y, width, height int)

CairoDrawFromGL: this is the main way to draw GL content in GTK+. It takes a render buffer ID (source_type == RENDERBUFFER) or a texture id (source_type == TEXTURE) and draws it onto cr with an OVER operation, respecting the current clip. The top left corner of the rectangle specified by x, y, width and height will be drawn at the current (0,0) position of the cairo_t.

This will work for *all* cairo_t, as long as window is realized, but the fallback implementation that reads back the pixels from the buffer may be used in the general case. In the case of direct drawing to a window with no special effects applied to cr it will however use a more efficient approach.

For RENDERBUFFER the code will always fall back to software for buffers with alpha components, so make sure you use TEXTURE if using alpha.

Calling this may change the current GL context.

The function takes the following parameters:

• cr: cairo context.
• window we're rendering for (not necessarily into).
• source: GL ID of the source buffer.
• sourceType: type of the source.
• bufferScale: scale-factor that the source buffer is allocated for.
• x: source x position in source to start copying from in GL coordinates.
• y: source y position in source to start copying from in GL coordinates.
• width of the region to draw.
• height of the region to draw.

This function takes into account device offsets that might be set with cairo_surface_set_device_offset().

The function takes the following parameters:

• surface: cairo surface.

The function returns the following values:

• region must be freed with cairo_region_destroy().

func CairoSetSourceColor

func CairoSetSourceColor(cr *cairo.Context, color *Color)

CairoSetSourceColor sets the specified Color as the source color of cr.

Deprecated: Use gdk_cairo_set_source_rgba() instead.

The function takes the following parameters:

• cr: cairo context.
• color: Color.

func CairoSetSourcePixbuf

func CairoSetSourcePixbuf(cr *cairo.Context, pixbuf *gdkpixbuf.Pixbuf, pixbufX, pixbufY float64)

CairoSetSourcePixbuf sets the given pixbuf as the source pattern for cr.

The pattern has an extend mode of CAIRO_EXTEND_NONE and is aligned so that the origin of pixbuf is pixbuf_x, pixbuf_y.

The function takes the following parameters:

• cr: cairo context.
• pixbuf: Pixbuf.
• pixbufX: x coordinate of location to place upper left corner of pixbuf.
• pixbufY: y coordinate of location to place upper left corner of pixbuf.

func CairoSetSourceRGBA

func CairoSetSourceRGBA(cr *cairo.Context, rgba *RGBA)

• rgba: RGBA.

func CairoSetSourceWindow

func CairoSetSourceWindow(cr *cairo.Context, window Windower, x, y float64)

CairoSetSourceWindow sets the given window as the source pattern for cr.

The pattern has an extend mode of CAIRO_EXTEND_NONE and is aligned so that the origin of window is x, y. The window contains all its subwindows when rendering.

Note that the contents of window are undefined outside of the visible part of window, so use this function with care.

The function takes the following parameters:

• cr: cairo context.
• window: Window.
• x: x coordinate of location to place upper left corner of window.
• y: y coordinate of location to place upper left corner of window.

func CairoSurfaceCreateFromPixbuf

func CairoSurfaceCreateFromPixbuf(pixbuf *gdkpixbuf.Pixbuf, scale int, forWindow Windower) *cairo.Surface

CairoSurfaceCreateFromPixbuf creates an image surface with the same contents as the pixbuf.

The function takes the following parameters:

• pixbuf: Pixbuf.
• scale of the new surface, or 0 to use same as window.
• forWindow (optional): window this will be drawn to, or NULL.

The function returns the following values:

• surface: new cairo surface, must be freed with cairo_surface_destroy().

func DisableMultidevice

func DisableMultidevice()

DisableMultidevice disables multidevice support in GDK. This call must happen prior to gdk_display_open(), gtk_init(), gtk_init_with_args() or gtk_init_check() in order to take effect.

Most common GTK+ applications won’t ever need to call this. Only applications that do mixed GDK/Xlib calls could want to disable multidevice support if such Xlib code deals with input devices in any way and doesn’t observe the presence of XInput 2.

func DragAbort

func DragAbort(context *DragContext, time_ uint32)

DragAbort aborts a drag without dropping.

This function is called by the drag source.

The function takes the following parameters:

• context: DragContext.
• success: whether the drag was ultimatively successful.

func DragDropSucceeded

func DragDropSucceeded(context *DragContext) bool

DragDropSucceeded returns whether the dropped data has been successfully transferred. This function is intended to be used while handling a GDK_DROP_FINISHED event, its return value is meaningless at other times.

The function returns the following values:

• ok: TRUE if the drop was successful.

func DragFindWindowForScreen

func DragFindWindowForScreen(context *DragContext, dragWindow Windower, screen *Screen, xRoot, yRoot int) (Windower, DragProtocol)

DragFindWindowForScreen finds the destination window and DND protocol to use at the given pointer position.

This function is called by the drag source to obtain the dest_window and protocol parameters for gdk_drag_motion().

This function does not need to be called in managed drag and drop operations. See gdk_drag_context_manage_dnd() for more information.

The function takes the following parameters:

• context: DragContext.
• destWindow: new destination window, obtained by gdk_drag_find_window().
• protocol: DND protocol in use, obtained by gdk_drag_find_window().

• accepted: TRUE if the drop is accepted.
• time_: timestamp for this operation.

func ErrorTrapPop

func ErrorTrapPop() int

ErrorTrapPop removes an error trap pushed with gdk_error_trap_push(). May block until an error has been definitively received or not received from the X server. gdk_error_trap_pop_ignored() is preferred if you don’t need to know whether an error occurred, because it never has to block. If you don't need the return value of gdk_error_trap_pop(), use gdk_error_trap_pop_ignored().

Prior to GDK 3.0, this function would not automatically sync for you, so you had to gdk_flush() if your last call to Xlib was not a blocking round trip.

The function returns the following values:

• gint: x error code or 0 on success.

func ErrorTrapPopIgnored

func ErrorTrapPopIgnored()

ErrorTrapPopIgnored removes an error trap pushed with gdk_error_trap_push(), but without bothering to wait and see whether an error occurred. If an error arrives later asynchronously that was triggered while the trap was pushed, that error will be ignored.

func ErrorTrapPush

func ErrorTrapPush()

ErrorTrapPush: this function allows X errors to be trapped instead of the normal behavior of exiting the application. It should only be used if it is not possible to avoid the X error in any other way. Errors are ignored on all Display currently known to the DisplayManager. If you don’t care which error happens and just want to ignore everything, pop with gdk_error_trap_pop_ignored(). If you need the error code, use gdk_error_trap_pop() which may have to block and wait for the error to arrive from the X server.

This API exists on all platforms but only does anything on X.

You can use gdk_x11_display_error_trap_push() to ignore errors on only a single display.

Trapping an X error

gdk_error_trap_push ();

 // ... Call the X function which may cause an error here ...

if (gdk_error_trap_pop ())
 {
   // ... Handle the error here ...
 }.

func EventHandlerSet

func EventHandlerSet(fn EventFunc)

EventHandlerSet sets the function to call to handle all events from GDK.

Note that GTK+ uses this to install its own event handler, so it is usually not useful for GTK+ applications. (Although an application can call this function then call gtk_main_do_event() to pass events to GTK+.).

The function takes the following parameters:

• fn: function to call to handle events from GDK.

func EventRequestMotions

func EventRequestMotions(event *EventMotion)

EventRequestMotions: request more motion notifies if event is a motion notify hint event.

This function should be used instead of gdk_window_get_pointer() to request further motion notifies, because it also works for extension events where motion notifies are provided for devices other than the core pointer. Coordinate extraction, processing and requesting more motion events from a GDK_MOTION_NOTIFY event usually works like this:

{
  // motion_event handler
  x = motion_event->x;
  y = motion_event->y;
  // handle (x,y) motion
  gdk_event_request_motions (motion_event); // handles is_hint events
}.

The function takes the following parameters:

• event: valid Event.

• event2: second Event.

The function returns the following values:

• x: return location for the X coordinate of the center.
• y: return location for the Y coordinate of the center.
• ok: TRUE if the center could be calculated.

func EventsGetDistance

func EventsGetDistance(event1, event2 *Event) (float64, bool)

NotifyStartupComplete indicates to the GUI environment that the application has finished loading. If the applications opens windows, this function is normally called after opening the application’s initial set of windows.

GTK+ will call this function automatically after opening the first Window unless gtk_window_set_auto_startup_notification() is called to disable that feature.

func NotifyStartupCompleteWithID

func NotifyStartupCompleteWithID(startupId string)

NotifyStartupCompleteWithID indicates to the GUI environment that the application has finished loading, using a given identifier.

To fully embed an offscreen window, in addition to calling this function, it is also necessary to handle the Window::pick-embedded-child signal on the embedder and the Window::to-embedder and Window::from-embedder signals on window.

The function takes the following parameters:

• window: Window.
• embedder that window gets embedded in.

func PangoContextGet

func PangoContextGet() *pango.Context

PangoContextGet creates a Context for the default GDK screen.

The context must be freed when you’re finished with it.

When using GTK+, normally you should use gtk_widget_get_pango_context() instead of this function, to get the appropriate context for the widget you intend to render text onto.

The newly created context will have the default font options (see #cairo_font_options_t) for the default screen; if these options change it will not be updated. Using gtk_widget_get_pango_context() is more convenient if you want to keep a context around and track changes to the screen’s font rendering settings.

When using GTK+, normally you should use gtk_widget_get_pango_context() instead of this function, to get the appropriate context for the widget you intend to render text onto.

The newly created context will have the default font options (see #cairo_font_options_t) for the display; if these options change it will not be updated. Using gtk_widget_get_pango_context() is more convenient if you want to keep a context around and track changes to the font rendering settings.

The function takes the following parameters:

• display for which the context is to be created.

The function returns the following values:

• context: new Context for display.

func PangoContextGetForScreen

func PangoContextGetForScreen(screen *Screen) *pango.Context

PangoContextGetForScreen creates a Context for screen.

The context must be freed when you’re finished with it.

When using GTK+, normally you should use gtk_widget_get_pango_context() instead of this function, to get the appropriate context for the widget you intend to render text onto.

The newly created context will have the default font options (see #cairo_font_options_t) for the screen; if these options change it will not be updated. Using gtk_widget_get_pango_context() is more convenient if you want to keep a context around and track changes to the screen’s font rendering settings.

The function takes the following parameters:

• screen for which the context is to be created.

The function returns the following values:

• context: new Context for screen.

func PixbufGetFromSurface

func PixbufGetFromSurface(surface *cairo.Surface, srcX, srcY, width, height int) *gdkpixbuf.Pixbuf

PixbufGetFromSurface transfers image data from a #cairo_surface_t and converts it to an RGB(A) representation inside a Pixbuf. This allows you to efficiently read individual pixels from cairo surfaces. For Windows, use gdk_pixbuf_get_from_window() instead.

This function will create an RGB pixbuf with 8 bits per channel. The pixbuf will contain an alpha channel if the surface contains one.

The function takes the following parameters:

• surface to copy from.
• srcX: source X coordinate within surface.
• srcY: source Y coordinate within surface.
• width: width in pixels of region to get.
• height: height in pixels of region to get.

The function returns the following values:

• pixbuf (optional): newly-created pixbuf with a reference count of 1, or NULL on error.

func PixbufGetFromWindow

func PixbufGetFromWindow(window Windower, srcX, srcY, width, height int) *gdkpixbuf.Pixbuf

PixbufGetFromWindow transfers image data from a Window and converts it to an RGB(A) representation inside a Pixbuf.

In other words, copies image data from a server-side drawable to a client-side RGB(A) buffer. This allows you to efficiently read individual pixels on the client side.

This function will create an RGB pixbuf with 8 bits per channel with the size specified by the width and height arguments scaled by the scale factor of window. The pixbuf will contain an alpha channel if the window contains one.

If the window is off the screen, then there is no image data in the obscured/offscreen regions to be placed in the pixbuf. The contents of portions of the pixbuf corresponding to the offscreen region are undefined.

If the window you’re obtaining data from is partially obscured by other windows, then the contents of the pixbuf areas corresponding to the obscured regions are undefined.

If the window is not mapped (typically because it’s iconified/minimized or not on the current workspace), then NULL will be returned.

If memory can’t be allocated for the return value, NULL will be returned instead.

In short, there are several ways this function can fail, and if it fails it returns NULL; so check the return value.

You should rarely, if ever, need to call this function.

The function takes the following parameters:

• window: source window.
• srcX: source X coordinate within window.
• srcY: source Y coordinate within window.
• width: width in pixels of region to get.
• height: height in pixels of region to get.

The function returns the following values:

• pixbuf (optional): newly-created pixbuf with a reference count of 1, or NULL on error.

func PointerIsGrabbed

func PointerIsGrabbed() bool

PointerIsGrabbed returns TRUE if the pointer on the default display is currently grabbed by this application.

Note that this does not take the inmplicit pointer grab on button presses into account.

Deprecated: Use gdk_display_device_is_grabbed() instead.

The function returns the following values:

• ok: TRUE if the pointer is currently grabbed by this application.

func PointerUngrab

func PointerUngrab(time_ uint32)

PointerUngrab ungrabs the pointer on the default display, if it is grabbed by this application.

Deprecated: Use gdk_device_ungrab(), together with gdk_device_grab() instead.

• time_: timestamp from a Event, or GDK_CURRENT_TIME if no timestamp is available.

func PreParseLibgtkOnly

func PreParseLibgtkOnly()

PreParseLibgtkOnly: prepare for parsing command line arguments for GDK. This is not public API and should not be used in application code.

Deprecated: This symbol was never meant to be used outside of GTK+.

func QueryDepths

func QueryDepths() []int

QueryDepths: this function returns the available bit depths for the default screen. It’s equivalent to listing the visuals (gdk_list_visuals()) and then looking at the depth field in each visual, removing duplicates.

The array returned by this function should not be freed.

Deprecated: Visual selection should be done using gdk_screen_get_system_visual() and gdk_screen_get_rgba_visual().

The function returns the following values:

• depths: return location for available depths.

func ScreenHeight

func ScreenHeight() int

Deprecated: Use per-monitor information.

The function returns the following values:

• gint: height of the default screen in pixels.

func ScreenHeightMm

func ScreenHeightMm() int

ScreenHeightMm returns the height of the default screen in millimeters. Note that on many X servers this value will not be correct.

func ScreenWidthMm

func ScreenWidthMm() int

ScreenWidthMm returns the width of the default screen in millimeters. Note that on many X servers this value will not be correct.

Deprecated: Use per-monitor information.

The function returns the following values:

• gint: width of the default screen in millimeters, though it is not always correct.

func SetAllowedBackends

func SetAllowedBackends(backends string)

SetAllowedBackends sets a list of backends that GDK should try to use.

This can be be useful if your application does not work with certain GDK backends.

By default, GDK tries all included backends.

For example,

gdk_set_allowed_backends ("wayland,quartz,*");

instructs GDK to try the Wayland backend first, followed by the Quartz backend, and then all others.

If the GDK_BACKEND environment variable is set, it determines what backends are tried in what order, while still respecting the set of allowed backends that are specified by this function.

The possible backend names are x11, win32, quartz, broadway, wayland. You can also include a * in the list to try all remaining backends.

This call must happen prior to gdk_display_open(), gtk_init(), gtk_init_with_args() or gtk_init_check() in order to take effect.

The function takes the following parameters:

• backends: comma-separated list of backends.

func SetDoubleClickTime

func SetDoubleClickTime(msec uint)

SetDoubleClickTime: set the double click time for the default display. See gdk_display_set_double_click_time(). See also gdk_display_set_double_click_distance(). Applications should not set this, it is a global user-configured setting.

The function takes the following parameters:

• msec: double click time in milliseconds (thousandths of a second).

func SetProgramClass

func SetProgramClass(programClass string)

SetProgramClass sets the program class. The X11 backend uses the program class to set the class name part of the WM_CLASS property on toplevel windows; see the ICCCM.

The program class can still be overridden with the --class command line option.

The function takes the following parameters:

• programClass: string.

func SetShowEvents

func SetShowEvents(showEvents bool)

SetShowEvents sets whether a trace of received events is output. Note that GTK+ must be compiled with debugging (that is, configured using the --enable-debug option) to use this option.

The function takes the following parameters:

• showEvents: TRUE to output event debugging information.

func SettingGet

func SettingGet(name string, value *coreglib.Value) bool

SettingGet obtains a desktop-wide setting, such as the double-click time, for the default screen. See gdk_screen_get_setting().

The function takes the following parameters:

• name of the setting.
• value: location to store the value of the setting.

The function returns the following values:

• ok: TRUE if the setting existed and a value was stored in value, FALSE otherwise.

func TestRenderSync

func TestRenderSync(window Windower)

TestRenderSync retrieves a pixel from window to force the windowing system to carry out any pending rendering commands.

This function is intended to be used to synchronize with rendering pipelines, to benchmark windowing system rendering operations.

The function takes the following parameters:

• window: mapped Window.

func TestSimulateButton

func TestSimulateButton(window Windower, x, y int, button uint, modifiers ModifierType, buttonPressrelease EventType) bool

TestSimulateButton: this function is intended to be used in GTK+ test programs. It will warp the mouse pointer to the given (x,y) coordinates within window and simulate a button press or release event. Because the mouse pointer needs to be warped to the target location, use of this function outside of test programs that run in their own virtual windowing system (e.g. Xvfb) is not recommended.

Also, gdk_test_simulate_button() is a fairly low level function, for most testing purposes, gtk_test_widget_click() is the right function to call which will generate a button press event followed by its accompanying button release event.

The function takes the following parameters:

• window to simulate a button event for.
• x coordinate within window for the button event.
• y coordinate within window for the button event.
• button: number of the pointer button for the event, usually 1, 2 or 3.
• modifiers: keyboard modifiers the event is setup with.
• buttonPressrelease: either GDK_BUTTON_PRESS or GDK_BUTTON_RELEASE.

The function returns the following values:

• ok: whether all actions necessary for a button event simulation were carried out successfully.

func TestSimulateKey

func TestSimulateKey(window Windower, x, y int, keyval uint, modifiers ModifierType, keyPressrelease EventType) bool

TestSimulateKey: this function is intended to be used in GTK+ test programs. If (x,y) are > (-1,-1), it will warp the mouse pointer to the given (x,y) coordinates within window and simulate a key press or release event.

When the mouse pointer is warped to the target location, use of this function outside of test programs that run in their own virtual windowing system (e.g. Xvfb) is not recommended. If (x,y) are passed as (-1,-1), the mouse pointer will not be warped and window origin will be used as mouse pointer location for the event.

Also, gdk_test_simulate_key() is a fairly low level function, for most testing purposes, gtk_test_widget_send_key() is the right function to call which will generate a key press event followed by its accompanying key release event.

The function takes the following parameters:

• window to simulate a key event for.
• x coordinate within window for the key event.
• y coordinate within window for the key event.
• keyval: GDK keyboard value.
• modifiers: keyboard modifiers the event is setup with.
• keyPressrelease: either GDK_KEY_PRESS or GDK_KEY_RELEASE.

The function returns the following values:

• ok: whether all actions necessary for a key event simulation were carried out successfully.

func ThreadsAddIdle

func ThreadsAddIdle(priority int, function glib.SourceFunc) uint

ThreadsAddIdle adds a function to be called whenever there are no higher priority events pending. If the function returns FALSE it is automatically removed from the list of event sources and will not be called again.

This variant of g_idle_add_full() calls function with the GDK lock held. It can be thought of a MT-safe version for GTK+ widgets for the following use case, where you have to worry about idle_callback() running in thread A and accessing self after it has been finalized in thread B:

static gboolean
idle_callback (gpointer data)
{
   // gdk_threads_enter(); would be needed for g_idle_add()

   SomeWidget *self = data;
   // do stuff with self

   self->idle_id = 0;

   // gdk_threads_leave(); would be needed for g_idle_add()
   return FALSE;
}

static void
some_widget_do_stuff_later (SomeWidget *self)
{
   self->idle_id = gdk_threads_add_idle (idle_callback, self)
   // using g_idle_add() here would require thread protection in the callback
}

static void
some_widget_finalize (GObject *object)
{
   SomeWidget *self = SOME_WIDGET (object);
   if (self->idle_id)
     g_source_remove (self->idle_id);
   G_OBJECT_CLASS (parent_class)->finalize (object);
}.

The function takes the following parameters:

• priority of the idle source. Typically this will be in the range between PRIORITY_DEFAULT_IDLE and PRIORITY_HIGH_IDLE.
• function to call.

The function returns the following values:

• guint: ID (greater than 0) of the event source.

func ThreadsAddTimeout

func ThreadsAddTimeout(priority int, interval uint, function glib.SourceFunc) uint

ThreadsAddTimeout sets a function to be called at regular intervals holding the GDK lock, with the given priority. The function is called repeatedly until it returns FALSE, at which point the timeout is automatically destroyed and the function will not be called again. The notify function is called when the timeout is destroyed. The first call to the function will be at the end of the first interval.

Note that timeout functions may be delayed, due to the processing of other event sources. Thus they should not be relied on for precise timing. After each call to the timeout function, the time of the next timeout is recalculated based on the current time and the given interval (it does not try to “catch up” time lost in delays).

This variant of g_timeout_add_full() can be thought of a MT-safe version for GTK+ widgets for the following use case:

static gboolean timeout_callback (gpointer data)
{
   SomeWidget *self = data;

   // do stuff with self

   self->timeout_id = 0;

   return G_SOURCE_REMOVE;
}

static void some_widget_do_stuff_later (SomeWidget *self)
{
   self->timeout_id = g_timeout_add (timeout_callback, self)
}

static void some_widget_finalize (GObject *object)
{
   SomeWidget *self = SOME_WIDGET (object);

   if (self->timeout_id)
     g_source_remove (self->timeout_id);

   G_OBJECT_CLASS (parent_class)->finalize (object);
}.

The function takes the following parameters:

• priority of the timeout source. Typically this will be in the range between PRIORITY_DEFAULT_IDLE and PRIORITY_HIGH_IDLE.
• interval: time between calls to the function, in milliseconds (1/1000ths of a second).
• function to call.

The function returns the following values:

• guint: ID (greater than 0) of the event source.

func ThreadsAddTimeoutSeconds

func ThreadsAddTimeoutSeconds(priority int, interval uint, function glib.SourceFunc) uint

ThreadsAddTimeoutSeconds: variant of gdk_threads_add_timeout_full() with second-granularity. See g_timeout_add_seconds_full() for a discussion of why it is a good idea to use this function if you don’t need finer granularity.

The function takes the following parameters:

• priority of the timeout source. Typically this will be in the range between PRIORITY_DEFAULT_IDLE and PRIORITY_HIGH_IDLE.
• interval: time between calls to the function, in seconds.
• function to call.

The function returns the following values:

• guint: ID (greater than 0) of the event source.

func ThreadsEnter

func ThreadsEnter()

ThreadsEnter: this function marks the beginning of a critical section in which GDK and GTK+ functions can be called safely and without causing race conditions. Only one thread at a time can be in such a critial section.

Deprecated: All GDK and GTK+ calls should be made from the main thread.

func ThreadsInit

func ThreadsInit()

ThreadsInit initializes GDK so that it can be used from multiple threads in conjunction with gdk_threads_enter() and gdk_threads_leave().

This call must be made before any use of the main loop from GTK+; to be safe, call it before gtk_init().

Deprecated: All GDK and GTK+ calls should be made from the main thread.

func ThreadsLeave

func ThreadsLeave()

ThreadsLeave leaves a critical region begun with gdk_threads_enter().

Deprecated: All GDK and GTK+ calls should be made from the main thread.

func UTF8ToStringTarget

func UTF8ToStringTarget(str string) string

UTF8ToStringTarget converts an UTF-8 string into the best possible representation as a STRING. The representation of characters not in STRING is not specified; it may be as pseudo-escape sequences \x{ABCD}, or it may be in some other form of approximation.

The function takes the following parameters:

• str: UTF-8 string.

The function returns the following values:

• utf8 (optional): newly-allocated string, or NULL if the conversion failed. (It should not fail for any properly formed UTF-8 string unless system limits like memory or file descriptors are exceeded.).

func UnicodeToKeyval

func UnicodeToKeyval(wc uint32) uint

UnicodeToKeyval: convert from a ISO10646 character to a key symbol.

The function takes the following parameters:

• wc: ISO10646 encoded character.

The function returns the following values:

• guint: corresponding GDK key symbol, if one exists. or, if there is no corresponding symbol, wc | 0x01000000.

func VisualGetBestDepth

func VisualGetBestDepth() int

VisualGetBestDepth: get the best available depth for the default GDK screen. “Best” means “largest,” i.e. 32 preferred over 24 preferred over 8 bits per pixel.

Deprecated: Visual selection should be done using gdk_screen_get_system_visual() and gdk_screen_get_rgba_visual().

The function returns the following values:

• gint: best available depth.

func WindowConstrainSize

func WindowConstrainSize(geometry *Geometry, flags WindowHints, width, height int) (newWidth, newHeight int)

WindowConstrainSize constrains a desired width and height according to a set of geometry hints (such as minimum and maximum size).

The function takes the following parameters:

• geometry: Geometry structure.
• flags: mask indicating what portions of geometry are set.
• width: desired width of window.
• height: desired height of the window.

The function returns the following values:

• newWidth: location to store resulting width.
• newHeight: location to store resulting height.

func WindowProcessAllUpdates

func WindowProcessAllUpdates()

WindowProcessAllUpdates calls gdk_window_process_updates() for all windows (see Window) in the application.

Deprecated: since version 3.22.

func WindowSetDebugUpdates

func WindowSetDebugUpdates(setting bool)

WindowSetDebugUpdates: with update debugging enabled, calls to gdk_window_invalidate_region() clear the invalidated region of the screen to a noticeable color, and GDK pauses for a short time before sending exposes to windows during gdk_window_process_updates(). The net effect is that you can see the invalid region for each window and watch redraws as they occur. This allows you to diagnose inefficiencies in your application.

In essence, because the GDK rendering model prevents all flicker, if you are redrawing the same region 400 times you may never notice, aside from noticing a speed problem. Enabling update debugging causes GTK to flicker slowly and noticeably, so you can see exactly what’s being redrawn when, in what order.

The --gtk-debug=updates command line option passed to GTK+ programs enables this debug option at application startup time. That's usually more useful than calling gdk_window_set_debug_updates() yourself, though you might want to use this function to enable updates sometime after application startup time.

Deprecated: since version 3.22.

The function takes the following parameters:

• setting: TRUE to turn on update debugging.

Types

type AnchorHints

type AnchorHints C.guint

AnchorHints: positioning hints for aligning a window relative to a rectangle.

These hints determine how the window should be positioned in the case that the window would fall off-screen if placed in its ideal position.

For example, GDK_ANCHOR_FLIP_X will replace GDK_GRAVITY_NORTH_WEST with GDK_GRAVITY_NORTH_EAST and vice versa if the window extends beyond the left or right edges of the monitor.

If GDK_ANCHOR_SLIDE_X is set, the window can be shifted horizontally to fit on-screen. If GDK_ANCHOR_RESIZE_X is set, the window can be shrunken horizontally to fit.

In general, when multiple flags are set, flipping should take precedence over sliding, which should take precedence over resizing.

const (
	// AnchorFlipX: allow flipping anchors horizontally.
	AnchorFlipX AnchorHints = 0b1
	// AnchorFlipY: allow flipping anchors vertically.
	AnchorFlipY AnchorHints = 0b10
	// AnchorSlideX: allow sliding window horizontally.
	AnchorSlideX AnchorHints = 0b100

	AnchorResizeX AnchorHints = 0b10000
	// AnchorResizeY: allow resizing window vertically.
	AnchorResizeY AnchorHints = 0b100000
	// AnchorFlip: allow flipping anchors on both axes.
	AnchorFlip AnchorHints = 0b11
	// AnchorSlide: allow sliding window on both axes.
	AnchorSlide AnchorHints = 0b1100
	// AnchorResize: allow resizing window on both axes.

The function takes the following parameters:

• screen: Screen.

func (*AppLaunchContext) SetTimestamp

func (context *AppLaunchContext) SetTimestamp(timestamp uint32)

SetTimestamp sets the timestamp of context. The timestamp should ideally be taken from the event that triggered the launch.

BaseDevice returns the underlying base object.

func (*Device) AssociatedDevice

func (device *Device) AssociatedDevice() Devicer

AssociatedDevice returns the associated device to device, if device is of type GDK_DEVICE_TYPE_MASTER, it will return the paired pointer or keyboard.

func (*Device) ConnectChanged

func (device *Device) ConnectChanged(f func()) coreglib.SignalHandle

ConnectChanged signal is emitted either when the Device has changed the number of either axes or keys. For example In X this will normally happen when the slave device routing events through the master device changes (for example, user switches from the USB mouse to a tablet), in that case the master device will change to reflect the new slave device axes and keys.

func (*Device) ConnectToolChanged

func (device *Device) ConnectToolChanged(f func(tool *DeviceTool)) coreglib.SignalHandle

ConnectToolChanged signal is emitted on pen/eraser Devices whenever tools enter or leave proximity.

func (*Device) Grab

func (device *Device) Grab(window Windower, grabOwnership GrabOwnership, ownerEvents bool, eventMask EventMask, cursor Cursorrer, time_ uint32) GrabStatus

Grab grabs the device so that all events coming from this device are passed to this application until the device is ungrabbed with gdk_device_ungrab(), or the window becomes unviewable. This overrides any previous grab on the device by this client.

Note that device and window need to be on the same display.

Device grabs are used for operations which need complete control over the given device events (either pointer or keyboard). For example in GTK+ this is used for Drag and Drop operations, popup menus and such.

Note that if the event mask of an X window has selected both button press and button release events, then a button press event will cause an automatic pointer grab until the button is released. X does this automatically since most applications expect to receive button press and release events in pairs. It is equivalent to a pointer grab on the window with owner_events set to TRUE.

If you set up anything at the time you take the grab that needs to be cleaned up when the grab ends, you should handle the EventGrabBroken events that are emitted when the grab ends unvoluntarily.

Deprecated: Use gdk_seat_grab() instead.

The function takes the following parameters:

• window which will own the grab (the grab window).
• grabOwnership specifies the grab ownership.
• ownerEvents: if FALSE then all device events are reported with respect to window and are only reported if selected by event_mask. If TRUE then pointer events for this application are reported as normal, but pointer events outside this application are reported with respect to window and only if selected by event_mask. In either mode, unreported events are discarded.
• eventMask specifies the event mask, which is used in accordance with owner_events.
• cursor (optional) to display while the grab is active if the device is a pointer. If this is NULL then the normal cursors are used for window and its descendants, and the cursor for window is used elsewhere.
• time_: timestamp of the event which led to this pointer grab. This usually comes from the Event struct, though GDK_CURRENT_TIME can be used if the time isn’t known.

The function returns the following values:

• grabStatus: GDK_GRAB_SUCCESS if the grab was successful.

func (*Device) HasCursor

func (device *Device) HasCursor() bool

HasCursor determines whether the pointer follows device motion. This is not meaningful for keyboard devices, which don't have a pointer.

func (*Device) Warp

func (device *Device) Warp(screen *Screen, x, y int)

Warp warps device in display to the point x,y on the screen screen, unless the device is confined to a window by a grab, in which case it will be moved as far as allowed by the grab. Warping the pointer creates events as if the user had moved the mouse instantaneously to the destination.

Note that the pointer should normally be under the control of the user. This function was added to cover some rare use cases like keyboard navigation support for the color picker in the ColorSelectionDialog.

The function takes the following parameters:

• screen to warp device to.
• x: x coordinate of the destination.
• y: y coordinate of the destination.

type DeviceManager

type DeviceManager struct {
	*coreglib.Object
	// contains filtered or unexported fields
}

DeviceManager: in addition to a single pointer and keyboard for user interface input, GDK contains support for a variety of input devices, including graphics tablets, touchscreens and multiple pointers/keyboards interacting simultaneously with the user interface. Such input devices often have additional features, such as sub-pixel positioning information and additional device-dependent information.

In order to query the device hierarchy and be aware of changes in the device hierarchy (such as virtual devices being created or removed, or physical devices being plugged or unplugged), GDK provides DeviceManager.

By default, and if the platform supports it, GDK is aware of multiple keyboard/pointer pairs and multitouch devices. This behavior can be changed by calling gdk_disable_multidevice() before gdk_display_open(). There should rarely be a need to do that though, since GDK defaults to a compatibility mode in which it will emit just one enter/leave event pair for all devices on a window. To enable per-device enter/leave events and other multi-pointer interaction features, gdk_window_set_support_multidevice() must be called on Windows (or gtk_widget_set_support_multidevice() on widgets). window. See the gdk_window_set_support_multidevice() documentation for more information.

On X11, multi-device support is implemented through XInput 2. Unless gdk_disable_multidevice() is called, the XInput 2 DeviceManager implementation will be used as the input source. Otherwise either the core or XInput 1 implementations will be used.

For simple applications that don’t have any special interest in input devices, the so-called “client pointer” provides a reasonable approximation to a simple setup with a single pointer and keyboard. The device that has been set as the client pointer can be accessed via gdk_device_manager_get_client_pointer().

Conceptually, in multidevice mode there are 2 device types. Virtual devices (or master devices) are represented by the pointer cursors and keyboard foci that are seen on the screen. Physical devices (or slave devices) represent the hardware that is controlling the virtual devices, and thus have no visible cursor on the screen.

Virtual devices are always paired, so there is a keyboard device for every pointer device. Associations between devices may be inspected through gdk_device_get_associated_device().

There may be several virtual devices, and several physical devices could be controlling each of these virtual devices. Physical devices may also be “floating”, which means they are not attached to any virtual device.

By default, GDK will automatically listen for events coming from all master devices, setting the Device for all events coming from input devices. Events containing device information are K_MOTION_NOTIFY, K_BUTTON_PRESS, K_2BUTTON_PRESS, K_3BUTTON_PRESS, K_BUTTON_RELEASE, K_SCROLL, K_KEY_PRESS, K_KEY_RELEASE, K_ENTER_NOTIFY, K_LEAVE_NOTIFY, K_FOCUS_CHANGE, K_PROXIMITY_IN, K_PROXIMITY_OUT, K_DRAG_ENTER, K_DRAG_LEAVE, K_DRAG_MOTION, K_DRAG_STATUS, K_DROP_START, K_DROP_FINISHED and K_GRAB_BROKEN. When dealing with an event on a master device, it is possible to get the source (slave) device that the event originated from via gdk_event_get_source_device().

On a standard session, all physical devices are connected by default to the "Virtual Core Pointer/Keyboard" master devices, hence routing all events through these. This behavior is only modified by device grabs, where the slave device is temporarily detached for as long as the grab is held, and more permanently by user modifications to the device hierarchy.

On certain application specific setups, it may make sense to detach a physical device from its master pointer, and mapping it to an specific window. This can be achieved by the combination of gdk_device_grab() and gdk_device_set_mode().

In order to listen for events coming from devices other than a virtual device, gdk_window_set_device_events() must be called. Generally, this function can be used to modify the event mask for any given device.

Input devices may also provide additional information besides X/Y. For example, graphics tablets may also provide pressure and X/Y tilt information. This information is device-dependent, and may be queried through gdk_device_get_axis(). In multidevice mode, virtual devices will change axes in order to always represent the physical device that is routing events through it. Whenever the physical device changes, the Device:n-axes property will be notified, and gdk_device_list_axes() will return the new device axes.

Devices may also have associated “keys” or macro buttons. Such keys can be globally set to map into normal X keyboard events. The mapping is set using gdk_device_set_key().

In GTK+ 3.20, a new Seat object has been introduced that supersedes DeviceManager and should be preferred in newly written code.

	// contains filtered or unexported fields
}

DevicePad is an interface implemented by devices of type GDK_SOURCE_TABLET_PAD, it allows querying the features provided by the pad device.

Tablet pads may contain one or more groups, each containing a subset of the buttons/rings/strips available. gdk_device_pad_get_n_groups() can be used to obtain the number of groups, gdk_device_pad_get_n_features() and gdk_device_pad_get_feature_group() can be combined to find out the number of buttons/rings/strips the device has, and how are they grouped.

Each of those groups have different modes, which may be used to map each individual pad feature to multiple actions. Only one mode is effective (current) for each given group, different groups may have different current modes. The number of available modes in a group can be found out through gdk_device_pad_get_group_n_modes(), and the current mode for a given group will be notified through the EventPadGroupMode event.

DevicePad wraps an interface. This means the user can get the underlying type by calling Cast().

func (*DevicePad) FeatureGroup

The function returns the following values:

• screen: Screen object.

func (*Display) SetDoubleClickDistance

func (display *Display) SetDoubleClickDistance(distance uint)

The function returns the following values:

• ok: TRUE if shaped windows are supported.

func (*Display) Sync

func (display *Display) Sync()

Sync flushes any requests queued for the windowing system and waits until all requests have been handled. This is often used for making sure that the display is synchronized with the current state of the program. Calling gdk_display_sync() before gdk_error_trap_pop() makes sure that any errors generated from earlier requests are handled before the error trap is removed.

This is most useful for X11. On windowing systems where requests are handled synchronously, this function will do nothing.

func (*Display) WarpPointer

func (display *Display) WarpPointer(screen *Screen, x, y int)

WarpPointer warps the pointer of display to the point x,y on the screen screen, unless the pointer is confined to a window by a grab, in which case it will be moved as far as allowed by the grab. Warping the pointer creates events as if the user had moved the mouse instantaneously to the destination.

Note that the pointer should normally be under the control of the user. This function was added to cover some rare use cases like keyboard navigation support for the color picker in the ColorSelectionDialog.

Deprecated: Use gdk_device_warp() instead.

The function returns the following values:

• winX (optional): return location for x coordinate of the pointer location relative to the window origin, or NULL.
• winY (optional): return location for y coordinate of the pointer location relative & to the window origin, or NULL.
• window (optional) under the mouse pointer, or NULL.

type DisplayManager

type DisplayManager struct {
	*coreglib.Object
	// contains filtered or unexported fields
}

DisplayManager: purpose of the DisplayManager singleton object is to offer notification when displays appear or disappear or the default display changes.

You can use gdk_display_manager_get() to obtain the DisplayManager singleton, but that should be rarely necessary. Typically, initializing GTK+ opens a display that you can work with without ever accessing the DisplayManager.

The GDK library can be built with support for multiple backends. The DisplayManager object determines which backend is used at runtime.

When writing backend-specific code that is supposed to work with multiple GDK backends, you have to consider both compile time and runtime. At compile time, use the K_WINDOWING_X11, K_WINDOWING_WIN32 macros, etc. to find out which backends are present in the GDK library you are building your application against. At runtime, use type-check macros like GDK_IS_X11_DISPLAY() to find out which backend is in use:

Backend-specific code

#ifdef GDK_WINDOWING_X11
  if (GDK_IS_X11_DISPLAY (display))
    {
      // make X11-specific calls here
    }
  else
#endif
#ifdef GDK_WINDOWING_QUARTZ
  if (GDK_IS_QUARTZ_DISPLAY (display))
    {
      // make Quartz-specific calls here
    }
  else
#endif
  g_error ("Unsupported GDK backend");.

func DisplayManagerGet

func DisplayManagerGet() *DisplayManager

DisplayManagerGet gets the singleton DisplayManager object.

When called for the first time, this function consults the GDK_BACKEND environment variable to find out which of the supported GDK backends to use (in case GDK has been compiled with multiple backends). Applications can use gdk_set_allowed_backends() to limit what backends can be used.

The function returns the following values:

• displayManager: global DisplayManager singleton; gdk_parse_args(), gdk_init(), or gdk_init_check() must have been called first.

func (*EventKey) String

func (e *EventKey) String() string

String: string containing an approximation of the text that would result from this keypress. The only correct way to handle text input of text is using input methods (see IMContext), so this field is deprecated and should never be used. (gdk_unicode_to_keyval() provides a non-deprecated way of getting an approximate translation for a key.) The string is encoded in the encoding of the current locale (Note: this for backwards compatibility: strings in GTK+ and GDK are typically in UTF-8.) and NUL-terminated. In some cases, the translation of the key code will be a single NUL byte, in which case looking at length is necessary to distinguish it from the an empty translation.

type EventMask

type EventMask C.guint

EventMask: set of bit-flags to indicate which events a window is to receive. Most of these masks map onto one or more of the EventType event types above.

See the [input handling overview][chap-input-handling] for details of [event masks][event-masks] and [event propagation][event-propagation].

GDK_POINTER_MOTION_HINT_MASK is deprecated. It is a special mask to reduce the number of GDK_MOTION_NOTIFY events received. When using GDK_POINTER_MOTION_HINT_MASK, fewer GDK_MOTION_NOTIFY events will be sent, some of which are marked as a hint (the is_hint member is TRUE). To receive more motion events after a motion hint event, the application needs to asks for more, by calling gdk_event_request_motions().

Since GTK 3.8, motion events are already compressed by default, independent of this mechanism. This compression can be disabled with gdk_window_set_event_compression(). See the documentation of that function for details.

If GDK_TOUCH_MASK is enabled, the window will receive touch events from touch-enabled devices. Those will come as sequences of EventTouch with type GDK_TOUCH_UPDATE, enclosed by two events with type GDK_TOUCH_BEGIN and GDK_TOUCH_END (or GDK_TOUCH_CANCEL). gdk_event_get_event_sequence() returns the event sequence for these events, so different sequences may be distinguished.

EventType specifies the type of the event.

Do not confuse these events with the signals that GTK+ widgets emit. Although many of these events result in corresponding signals being emitted, the events are often transformed or filtered along the way.

In some language bindings, the values GDK_2BUTTON_PRESS and GDK_3BUTTON_PRESS would translate into something syntactically invalid (eg Gdk.EventType.2ButtonPress, where a symbol is not allowed to start with a number). In that case, the aliases GDK_DOUBLE_BUTTON_PRESS and GDK_TRIPLE_BUTTON_PRESS can be used instead.

type FrameClock

type FrameClock struct {
	*coreglib.Object
	// contains filtered or unexported fields
}

FrameClock tells the application when to update and repaint a window. This may be synced to the vertical refresh rate of the monitor, for example. Even when the frame clock uses a simple timer rather than a hardware-based vertical sync, the frame clock helps because it ensures everything paints at the same time (reducing the total number of frames). The frame clock can also automatically stop painting when it knows the frames will not be visible, or scale back animation framerates.

FrameClock is designed to be compatible with an OpenGL-based implementation or with mozRequestAnimationFrame in Firefox, for example.

A frame clock is idle until someone requests a frame with gdk_frame_clock_request_phase(). At some later point that makes sense for the synchronization being implemented, the clock will process a frame and emit signals for each phase that has been requested. (See the signals of the FrameClock class for documentation of the phases. GDK_FRAME_CLOCK_PHASE_UPDATE and the FrameClock::update signal are most interesting for application writers, and are used to update the animations, using the frame time given by gdk_frame_clock_get_frame_time().

The frame time is reported in microseconds and generally in the same timescale as g_get_monotonic_time(), however, it is not the same as g_get_monotonic_time(). The frame time does not advance during the time a frame is being painted, and outside of a frame, an attempt is made so that all calls to gdk_frame_clock_get_frame_time() that are called at a “similar” time get the same value. This means that if different animations are timed by looking at the difference in time between an initial value from gdk_frame_clock_get_frame_time() and the value inside the FrameClock::update signal of the clock, they will stay exactly synchronized.

func BaseFrameClock

func BaseFrameClock(obj FrameClocker) *FrameClock

BaseFrameClock returns the underlying base object.

func (*FrameClock) BeginUpdating

func (frameClock *FrameClock) BeginUpdating()

BeginUpdating starts updates for an animation. Until a matching call to gdk_frame_clock_end_updating() is made, the frame clock will continually request a new frame with the GDK_FRAME_CLOCK_PHASE_UPDATE phase. This function may be called multiple times and frames will be requested until gdk_frame_clock_end_updating() is called the same number of times.

func (*FrameClock) ConnectAfterPaint

func (frameClock *FrameClock) ConnectAfterPaint(f func()) coreglib.SignalHandle

ConnectAfterPaint: this signal ends processing of the frame. Applications should generally not handle this signal.

func (*FrameClock) ConnectBeforePaint

func (frameClock *FrameClock) ConnectBeforePaint(f func()) coreglib.SignalHandle

ConnectBeforePaint: this signal begins processing of the frame. Applications should generally not handle this signal.

func (*FrameClock) ConnectFlushEvents

func (frameClock *FrameClock) ConnectFlushEvents(f func()) coreglib.SignalHandle

ConnectFlushEvents: this signal is used to flush pending motion events that are being batched up and compressed together. Applications should not handle this signal.

func (*FrameClock) ConnectLayout

func (frameClock *FrameClock) ConnectLayout(f func()) coreglib.SignalHandle

ConnectLayout: this signal is emitted as the second step of toolkit and application processing of the frame. Any work to update sizes and positions of application elements should be performed. GTK+ normally handles this internally.

func (*FrameClock) ConnectPaint

func (frameClock *FrameClock) ConnectPaint(f func()) coreglib.SignalHandle

ConnectPaint: this signal is emitted as the third step of toolkit and application processing of the frame. The frame is repainted. GDK normally handles this internally and produces expose events, which are turned into GTK+ Widget::draw signals.

func (*FrameClock) ConnectResumeEvents

func (frameClock *FrameClock) ConnectResumeEvents(f func()) coreglib.SignalHandle

ConnectResumeEvents: this signal is emitted after processing of the frame is finished, and is handled internally by GTK+ to resume normal event processing. Applications should not handle this signal.

func (*FrameClock) ConnectUpdate

func (frameClock *FrameClock) ConnectUpdate(f func()) coreglib.SignalHandle

ConnectUpdate: this signal is emitted as the first step of toolkit and application processing of the frame. Animations should be updated using gdk_frame_clock_get_frame_time(). Applications can connect directly to this signal, or use gtk_widget_add_tick_callback() as a more convenient interface.

func (*FrameClock) CurrentTimings

func (frameClock *FrameClock) CurrentTimings() *FrameTimings

CurrentTimings gets the frame timings for the current frame.

The function returns the following values:

• frameTimings (optional) for the frame currently being processed, or even no frame is being processed, for the previous frame. Before any frames have been processed, returns NULL.

func (frameClock *FrameClock) EndUpdating()

EndUpdating stops updates for an animation. See the documentation for gdk_frame_clock_begin_updating().

func (*FrameClock) FrameCounter

func (frameClock *FrameClock) FrameCounter() int64

FrameCounter maintains a 64-bit counter that increments for each frame drawn.

The function returns the following values:

• gint64: inside frame processing, the value of the frame counter for the current frame. Outside of frame processing, the frame counter for the last frame.

func (*FrameClock) FrameTime

func (frameClock *FrameClock) FrameTime() int64

FrameTime gets the time that should currently be used for animations. Inside the processing of a frame, it’s the time used to compute the animation position of everything in a frame. Outside of a frame, it's the time of the conceptual “previous frame,” which may be either the actual previous frame time, or if that’s too old, an updated time.

The function returns the following values:

• gint64: timestamp in microseconds, in the timescale of of g_get_monotonic_time().

func (*FrameClock) HistoryStart

func (frameClock *FrameClock) HistoryStart() int64

HistoryStart internally keeps a history of FrameTimings objects for recent frames that can be retrieved with gdk_frame_clock_get_timings(). The set of stored frames is the set from the counter values given by gdk_frame_clock_get_history_start() and gdk_frame_clock_get_frame_counter(), inclusive.

The function returns the following values:

• gint64: frame counter value for the oldest frame that is available in the internal frame history of the FrameClock.

func (*FrameClock) RefreshInfo

func (frameClock *FrameClock) RefreshInfo(baseTime int64) (refreshIntervalReturn, presentationTimeReturn int64)

RefreshInfo: using the frame history stored in the frame clock, finds the last known presentation time and refresh interval, and assuming that presentation times are separated by the refresh interval, predicts a presentation time that is a multiple of the refresh interval after the last presentation time, and later than base_time.

The function takes the following parameters:

• baseTime: base time for determining a presentaton time.

The function returns the following values:

• refreshIntervalReturn (optional): location to store the determined refresh interval, or NULL. A default refresh interval of 1/60th of a second will be stored if no history is present.
• presentationTimeReturn: location to store the next candidate presentation time after the given base time. 0 will be will be stored if no history is present.

func (*FrameClock) RequestPhase

func (frameClock *FrameClock) RequestPhase(phase FrameClockPhase)

RequestPhase asks the frame clock to run a particular phase. The signal corresponding the requested phase will be emitted the next time the frame clock processes. Multiple calls to gdk_frame_clock_request_phase() will be combined together and only one frame processed. If you are displaying animated content and want to continually request the GDK_FRAME_CLOCK_PHASE_UPDATE phase for a period of time, you should use gdk_frame_clock_begin_updating() instead, since this allows GTK+ to adjust system parameters to get maximally smooth animations.

The function takes the following parameters:

• phase that is requested.

func (*FrameClock) Timings

func (frameClock *FrameClock) Timings(frameCounter int64) *FrameTimings

Timings retrieves a FrameTimings object holding timing information for the current frame or a recent frame. The FrameTimings object may not yet be complete: see gdk_frame_timings_get_complete().

The function takes the following parameters:

• frameCounter: frame counter value identifying the frame to be received.

The function returns the following values:

• frameTimings (optional) object for the specified frame, or NULL if it is not available. See gdk_frame_clock_get_history_start().

type FrameClockPhase

type FrameClockPhase C.guint

FrameClockPhase is used to represent the different paint clock phases that can be requested. The elements of the enumeration correspond to the signals of FrameClock.

const (
	// FrameClockPhaseNone: no phase.
	FrameClockPhaseNone FrameClockPhase = 0b0
	// FrameClockPhaseFlushEvents corresponds to GdkFrameClock::flush-events.
	// Should not be handled by applications.
	FrameClockPhaseFlushEvents FrameClockPhase = 0b1
	// FrameClockPhaseBeforePaint corresponds to GdkFrameClock::before-paint.
	// Should not be handled by applications.
	FrameClockPhaseBeforePaint FrameClockPhase = 0b10
	// FrameClockPhaseUpdate corresponds to GdkFrameClock::update.
	FrameClockPhaseUpdate FrameClockPhase = 0b100
	// FrameClockPhaseLayout corresponds to GdkFrameClock::layout.
	FrameClockPhaseLayout FrameClockPhase = 0b1000
	// FrameClockPhasePaint corresponds to GdkFrameClock::paint.
	FrameClockPhasePaint FrameClockPhase = 0b10000
	// FrameClockPhaseResumeEvents corresponds to GdkFrameClock::resume-events.
	// Should not be handled by applications.
	FrameClockPhaseResumeEvents FrameClockPhase = 0b100000
	// FrameClockPhaseAfterPaint corresponds to GdkFrameClock::after-paint.

type FrameClocker interface {
	coreglib.Objector
	// contains filtered or unexported methods
}

FrameClocker describes types inherited from class FrameClock.

To get the original type, the caller must assert this to an interface or another type.

type FrameTimings

type FrameTimings struct {
	// contains filtered or unexported fields
}

FrameTimings object holds timing information for a single frame of the application’s displays. To retrieve FrameTimings objects, use gdk_frame_clock_get_timings() or gdk_frame_clock_get_current_timings(). The information in FrameTimings is useful for precise synchronization of video with the event or audio streams, and for measuring quality metrics for the application’s display, such as latency and jitter.

An instance of this type is always passed by reference.

func (*FrameTimings) Complete

func (timings *FrameTimings) Complete() bool

Complete: timing information in a FrameTimings is filled in incrementally as the frame as drawn and passed off to the window system for processing and display to the user. The accessor functions for FrameTimings can return 0 to indicate an unavailable value for two reasons: either because the information is not yet available, or because it isn't available at all. Once gdk_frame_timings_get_complete() returns TRUE for a frame, you can be certain that no further values will become available and be stored in the FrameTimings.

The function returns the following values:

• ok: TRUE if all information that will be available for the frame has been filled in.

func (*FrameTimings) FrameCounter

func (timings *FrameTimings) FrameCounter() int64

The function returns the following values:

• gint64: frame counter value for this frame.

func (*FrameTimings) FrameTime

FrameTime returns the frame time for the frame. This is the time value that is typically used to time animations for the frame. See gdk_frame_clock_get_frame_time().

The function returns the following values:

• gint64: frame time for the frame, in the timescale of g_get_monotonic_time().

func (*FrameTimings) PredictedPresentationTime

func (timings *FrameTimings) PredictedPresentationTime() int64

PredictedPresentationTime gets the predicted time at which this frame will be displayed. Although no predicted time may be available, if one is available, it will be available while the frame is being generated, in contrast to gdk_frame_timings_get_presentation_time(), which is only available after the frame has been presented. In general, if you are simply animating, you should use gdk_frame_clock_get_frame_time() rather than this function, but this function is useful for applications that want exact control over latency. For example, a movie player may want this information for Audio/Video synchronization.

The function returns the following values:

• gint64: predicted time at which the frame will be presented, in the timescale of g_get_monotonic_time(), or 0 if no predicted presentation time is available.

func (*FrameTimings) PresentationTime

func (timings *FrameTimings) PresentationTime() int64

PresentationTime reurns the presentation time. This is the time at which the frame became visible to the user.

The function returns the following values:

• gint64: time the frame was displayed to the user, in the timescale of g_get_monotonic_time(), or 0 if no presentation time is available. See gdk_frame_timings_get_complete().

func (*FrameTimings) RefreshInterval

func (timings *FrameTimings) RefreshInterval() int64

RefreshInterval gets the natural interval between presentation times for the display that this frame was displayed on. Frame presentation usually happens during the “vertical blanking interval”.

The function returns the following values:

• gint64: refresh interval of the display, in microseconds, or 0 if the refresh interval is not available. See gdk_frame_timings_get_complete().

type FullscreenMode

type FullscreenMode C.gint

FullscreenMode indicates which monitor (in a multi-head setup) a window should span over when in fullscreen mode.

const (
	// FullscreenOnCurrentMonitor: fullscreen on current monitor only.
	FullscreenOnCurrentMonitor FullscreenMode = iota
	// FullscreenOnAllMonitors: span across all monitors when fullscreen.
	FullscreenOnAllMonitors
)

func (FullscreenMode) String

func (f FullscreenMode) String() string

String returns the name in string for FullscreenMode.

type GLContext

type GLContext struct {
	*coreglib.Object
	// contains filtered or unexported fields
}

GLContext is an object representing the platform-specific OpenGL drawing context.

GLContexts are created for a Window using gdk_window_create_gl_context(), and the context will match the Visual of the window.

A GLContext is not tied to any particular normal framebuffer. For instance, it cannot draw to the Window back buffer. The GDK repaint system is in full control of the painting to that. Instead, you can create render buffers or textures and use gdk_cairo_draw_from_gl() in the draw function of your widget to draw them. Then GDK will handle the integration of your rendering with that of other widgets.

Support for GLContext is platform-specific, context creation can fail, returning NULL context.

A GLContext has to be made "current" in order to start using it, otherwise any OpenGL call will be ignored.

Creating a new OpenGL context ##

In order to create a new GLContext instance you need a Window, which you typically get during the realize call of a widget.

A GLContext is not realized until either gdk_gl_context_make_current(), or until it is realized using gdk_gl_context_realize(). It is possible to specify details of the GL context like the OpenGL version to be used, or whether the GL context should have extra state validation enabled after calling gdk_window_create_gl_context() by calling gdk_gl_context_realize(). If the realization fails you have the option to change the settings of the GLContext and try again.

Using a GdkGLContext ##

You will need to make the GLContext the current context before issuing OpenGL calls; the system sends OpenGL commands to whichever context is current. It is possible to have multiple contexts, so you always need to ensure that the one which you want to draw with is the current one before issuing commands:

gdk_gl_context_make_current (context);

You can now perform your drawing using OpenGL commands.

You can check which GLContext is the current one by using gdk_gl_context_get_current(); you can also unset any GLContext that is currently set by calling gdk_gl_context_clear_current().

func (*GLContext) IsLegacy

func (context *GLContext) IsLegacy() bool

IsLegacy: whether the GLContext is in legacy mode or not.

The GLContext must be realized before calling this function.

When realizing a GL context, GDK will try to use the OpenGL 3.2 core profile; this profile removes all the OpenGL API that was deprecated prior to the 3.2 version of the specification. If the realization is successful, this function will return FALSE.

If the underlying OpenGL implementation does not support core profiles, GDK will fall back to a pre-3.2 compatibility profile, and this function will return TRUE.

You can use the value returned by this function to decide which kind of OpenGL API to use, or whether to do extension discovery, or what kind of shader programs to load.

The function returns the following values:

• ok: TRUE if the GL context is in legacy mode.

func (*GLContext) MakeCurrent

func (context *GLContext) MakeCurrent()

MakeCurrent makes the context the current one.

The function takes the following parameters:

• compatible: whether the context should be forward compatible.

func (*GLContext) SetRequiredVersion

func (context *GLContext) SetRequiredVersion(major, minor int)

SetRequiredVersion sets the major and minor version of OpenGL to request.

The function takes the following parameters:

• major version to request.
• minor version to request.

func (*GLContext) SetUseES

func (context *GLContext) SetUseES(useEs int)

SetUseES requests that GDK create a OpenGL ES context instead of an OpenGL one, if the platform and windowing system allows it.

The context must not have been realized.

By default, GDK will attempt to automatically detect whether the underlying GL implementation is OpenGL or OpenGL ES once the context is realized.

You should check the return value of gdk_gl_context_get_use_es() after calling gdk_gl_context_realize() to decide whether to use the OpenGL or OpenGL ES API, extensions, or shaders.

The function takes the following parameters:

• useEs: whether the context should use OpenGL ES instead of OpenGL, or -1 to allow auto-detection.

	// GLErrorUnsupportedFormat: requested visual format is not supported.
	GLErrorUnsupportedFormat
	// GLErrorUnsupportedProfile: requested profile is not supported.
	GLErrorUnsupportedProfile
)

func (GLError) String

func (g GLError) String() string

String returns the name in string for GLError.

type Geometry

type Geometry struct {
	// contains filtered or unexported fields
}

Geometry struct gives the window manager information about a window’s geometry constraints. Normally you would set these on the GTK+ level using gtk_window_set_geometry_hints(). Window then sets the hints on the Window it creates.

gdk_window_set_geometry_hints() expects the hints to be fully valid already and simply passes them to the window manager; in contrast, gtk_window_set_geometry_hints() performs some interpretation. For example, Window will apply the hints to the geometry widget instead of the toplevel window, if you set a geometry widget. Also, the min_width/min_height/max_width/max_height fields may be set to -1, and Window will substitute the size request of the window or geometry widget. If the minimum size hint is not provided, Window will use its requisition as the minimum size. If the minimum size is provided and a geometry widget is set, Window will take the minimum size as the minimum size of the geometry widget rather than the entire window. The base size is treated similarly.

The canonical use-case for gtk_window_set_geometry_hints() is to get a terminal widget to resize properly. Here, the terminal text area should be the geometry widget; Window will then automatically set the base size to the size of other widgets in the terminal window, such as the menubar and scrollbar. Then, the width_inc and height_inc fields should be set to the size of one character in the terminal. Finally, the base size should be set to the size of one character. The net effect is that the minimum size of the terminal will have a 1x1 character terminal area, and only terminal sizes on the “character grid” will be allowed.

Here’s an example of how the terminal example would be implemented, assuming a terminal area widget called “terminal” and a toplevel window “toplevel”:

	GdkGeometry hints;

	hints.base_width = terminal->char_width;
        hints.base_height = terminal->char_height;
        hints.min_width = terminal->char_width;
        hints.min_height = terminal->char_height;
        hints.width_inc = terminal->char_width;
        hints.height_inc = terminal->char_height;

 gtk_window_set_geometry_hints (GTK_WINDOW (toplevel),
                                GTK_WIDGET (terminal),
                                &hints,
                                GDK_HINT_RESIZE_INC |
                                GDK_HINT_MIN_SIZE |
                                GDK_HINT_BASE_SIZE);

The other useful fields are the min_aspect and max_aspect fields; these contain a width/height ratio as a floating point number. If a geometry widget is set, the aspect applies to the geometry widget rather than the entire window. The most common use of these hints is probably to set min_aspect and max_aspect to the same value, thus forcing the window to keep a constant aspect ratio.

An instance of this type is always passed by reference.

	GrabFrozen
	// GrabFailed: grab failed for some other reason. Since 3.16.
	GrabFailed
)

func KeyboardGrab

func KeyboardGrab(window Windower, ownerEvents bool, time_ uint32) GrabStatus

KeyboardGrab grabs the keyboard so that all events are passed to this application until the keyboard is ungrabbed with gdk_keyboard_ungrab(). This overrides any previous keyboard grab by this client.

If you set up anything at the time you take the grab that needs to be cleaned up when the grab ends, you should handle the EventGrabBroken events that are emitted when the grab ends unvoluntarily.

Deprecated: Use gdk_device_grab() instead.

The function takes the following parameters:

• window which will own the grab (the grab window).
• ownerEvents: if FALSE then all keyboard events are reported with respect to window. If TRUE then keyboard events for this application are reported as normal, but keyboard events outside this application are reported with respect to window. Both key press and key release events are always reported, independant of the event mask set by the application.
• time_: timestamp from a Event, or GDK_CURRENT_TIME if no timestamp is available.

The function returns the following values:

• grabStatus: GDK_GRAB_SUCCESS if the grab was successful.

func PointerGrab

func PointerGrab(window Windower, ownerEvents bool, eventMask EventMask, confineTo Windower, cursor Cursorrer, time_ uint32) GrabStatus

PointerGrab grabs the pointer (usually a mouse) so that all events are passed to this application until the pointer is ungrabbed with gdk_pointer_ungrab(), or the grab window becomes unviewable. This overrides any previous pointer grab by this client.

Pointer grabs are used for operations which need complete control over mouse events, even if the mouse leaves the application. For example in GTK+ it is used for Drag and Drop, for dragging the handle in the HPaned and VPaned widgets.

Note that if the event mask of an X window has selected both button press and button release events, then a button press event will cause an automatic pointer grab until the button is released. X does this automatically since most applications expect to receive button press and release events in pairs. It is equivalent to a pointer grab on the window with owner_events set to TRUE.

If you set up anything at the time you take the grab that needs to be cleaned up when the grab ends, you should handle the EventGrabBroken events that are emitted when the grab ends unvoluntarily.

Deprecated: Use gdk_device_grab() instead.

The function takes the following parameters:

• window which will own the grab (the grab window).
• ownerEvents: if FALSE then all pointer events are reported with respect to window and are only reported if selected by event_mask. If TRUE then pointer events for this application are reported as normal, but pointer events outside this application are reported with respect to window and only if selected by event_mask. In either mode, unreported events are discarded.
• eventMask specifies the event mask, which is used in accordance with owner_events. Note that only pointer events (i.e. button and motion events) may be selected.
• confineTo (optional): if non-NULL, the pointer will be confined to this window during the grab. If the pointer is outside confine_to, it will automatically be moved to the closest edge of confine_to and enter and leave events will be generated as necessary.
• cursor (optional) to display while the grab is active. If this is NULL then the normal cursors are used for window and its descendants, and the cursor for window is used for all other windows.
• time_: timestamp of the event which led to this pointer grab. This usually comes from a EventButton struct, though GDK_CURRENT_TIME can be used if the time isn’t known.

The function returns the following values:

• grabStatus: GDK_GRAB_SUCCESS if the grab was successful.

func (GrabStatus) String

func (InputSource) String

func (i InputSource) String() string

String returns the name in string for InputSource.

type Keymap

type Keymap struct {
	*coreglib.Object
	// contains filtered or unexported fields
}

Keymap defines the translation from keyboard state (including a hardware key, a modifier mask, and active keyboard group) to a keyval. This translation has two phases. The first phase is to determine the effective keyboard group and level for the keyboard state; the second phase is to look up the keycode/group/level triplet in the keymap and see what keyval it corresponds to.

func KeymapGetDefault

func KeymapGetDefault() *Keymap

KeymapGetDefault returns the Keymap attached to the default display.

Deprecated: Use gdk_keymap_get_for_display() instead.

The function returns the following values:

• keymap attached to the default display.

func KeymapGetForDisplay

func KeymapGetForDisplay(display *Display) *Keymap

KeymapGetForDisplay returns the Keymap attached to display.

The function takes the following parameters:

• display: Display.

The function returns the following values:

• keymap attached to display.

func (*Keymap) CapsLockState

func (keymap *Keymap) CapsLockState() bool

CapsLockState returns whether the Caps Lock modifer is locked.

The function returns the following values:

• ok: TRUE if Caps Lock is on.

func (*Keymap) ConnectDirectionChanged

func (keymap *Keymap) ConnectDirectionChanged(f func()) coreglib.SignalHandle

ConnectDirectionChanged signal gets emitted when the direction of the keymap changes.

func (*Keymap) ConnectKeysChanged

func (keymap *Keymap) ConnectKeysChanged(f func()) coreglib.SignalHandle

ConnectKeysChanged signal is emitted when the mapping represented by keymap changes.

func (*Keymap) ConnectStateChanged

func (keymap *Keymap) ConnectStateChanged(f func()) coreglib.SignalHandle

ConnectStateChanged signal is emitted when the state of the keyboard changes, e.g when Caps Lock is turned on or off. See gdk_keymap_get_caps_lock_state().

func (*Keymap) Direction

func (keymap *Keymap) Direction() pango.Direction

Direction returns the direction of effective layout of the keymap.

The function returns the following values:

• direction: PANGO_DIRECTION_LTR or PANGO_DIRECTION_RTL if it can determine the direction. PANGO_DIRECTION_NEUTRAL otherwise.

func (*Keymap) EntriesForKeycode

func (keymap *Keymap) EntriesForKeycode(hardwareKeycode uint) ([]KeymapKey, []uint, bool)

EntriesForKeycode returns the keyvals bound to hardware_keycode. The Nth KeymapKey in keys is bound to the Nth keyval in keyvals. Free the returned arrays with g_free(). When a keycode is pressed by the user, the keyval from this list of entries is selected by considering the effective keyboard group and level. See gdk_keymap_translate_keyboard_state().

The function takes the following parameters:

• hardwareKeycode: keycode.

The function returns the following values:

• keys (optional): return location for array of KeymapKey, or NULL.
• keyvals (optional): return location for array of keyvals, or NULL.
• ok: TRUE if there were any entries.

func (*Keymap) EntriesForKeyval

func (keymap *Keymap) EntriesForKeyval(keyval uint) ([]KeymapKey, bool)

EntriesForKeyval obtains a list of keycode/group/level combinations that will generate keyval. Groups and levels are two kinds of keyboard mode; in general, the level determines whether the top or bottom symbol on a key is used, and the group determines whether the left or right symbol is used. On US keyboards, the shift key changes the keyboard level, and there are no groups. A group switch key might convert a keyboard between Hebrew to English modes, for example. EventKey contains a group field that indicates the active keyboard group. The level is computed from the modifier mask. The returned array should be freed with g_free().

The function takes the following parameters:

• keyval: keyval, such as GDK_KEY_a, GDK_KEY_Up, GDK_KEY_Return, etc.

The function returns the following values:

• keys: return location for an array of KeymapKey.
• ok: TRUE if keys were found and returned.

func (*Keymap) HaveBidiLayouts

func (keymap *Keymap) HaveBidiLayouts() bool

HaveBidiLayouts determines if keyboard layouts for both right-to-left and left-to-right languages are in use.

The function returns the following values:

• ok: TRUE if there are layouts in both directions, FALSE otherwise.

func (*Keymap) LookupKey

func (keymap *Keymap) LookupKey(key *KeymapKey) uint

LookupKey looks up the keyval mapped to a keycode/group/level triplet. If no keyval is bound to key, returns 0. For normal user input, you want to use gdk_keymap_translate_keyboard_state() instead of this function, since the effective group/level may not be the same as the current keyboard state.

The function takes the following parameters:

• key with keycode, group, and level initialized.

The function returns the following values:

• guint: keyval, or 0 if none was mapped to the given key.

func (*Keymap) ModifierMask

func (keymap *Keymap) ModifierMask(intent ModifierIntent) ModifierType

ModifierMask returns the modifier mask the keymap’s windowing system backend uses for a particular purpose.

Note that this function always returns real hardware modifiers, not virtual ones (e.g. it will return K_MOD1_MASK rather than K_META_MASK if the backend maps MOD1 to META), so there are use cases where the return value of this function has to be transformed by gdk_keymap_add_virtual_modifiers() in order to contain the expected result.

The function takes the following parameters:

• intent: use case for the modifier mask.

The function returns the following values:

• modifierType: modifier mask used for intent.

func (*Keymap) ModifierState

func (keymap *Keymap) ModifierState() uint

ModifierState returns the current modifier state.

The function returns the following values:

• guint: current modifier state.

func (*Keymap) NumLockState

func (keymap *Keymap) NumLockState() bool

NumLockState returns whether the Num Lock modifer is locked.

The function returns the following values:

• ok: TRUE if Num Lock is on.

func (*Keymap) ScrollLockState

func (keymap *Keymap) ScrollLockState() bool

ScrollLockState returns whether the Scroll Lock modifer is locked.

The function returns the following values:

• ok: TRUE if Scroll Lock is on.

func (*Keymap) TranslateKeyboardState

func (keymap *Keymap) TranslateKeyboardState(hardwareKeycode uint, state ModifierType, group int) (keyval uint, effectiveGroup, level int, consumedModifiers ModifierType, ok bool)

TranslateKeyboardState translates the contents of a EventKey into a keyval, effective group, and level. Modifiers that affected the translation and are thus unavailable for application use are returned in consumed_modifiers. See [Groups][key-group-explanation] for an explanation of groups and levels. The effective_group is the group that was actually used for the translation; some keys such as Enter are not affected by the active keyboard group. The level is derived from state. For convenience, EventKey already contains the translated keyval, so this function isn’t as useful as you might think.

consumed_modifiers gives modifiers that should be masked outfrom state when comparing this key press to a hot key. For instance, on a US keyboard, the plus symbol is shifted, so when comparing a key press to a <Control>plus accelerator <Shift> should be masked out.

// XXX Don’t do this XXX
if (keyval == accel_keyval &&
    (event->state & ~consumed & ALL_ACCELS_MASK) == (accel_mods & ~consumed))
  // Accelerator was pressed

However, this did not work if multi-modifier combinations were used in the keymap, since, for instance, <Control> would be masked out even if only <Control><Alt> was used in the keymap. To support this usage as well as well as possible, all single modifier combinations that could affect the key for any combination of modifiers will be returned in consumed_modifiers; multi-modifier combinations are returned only when actually found in state. When you store accelerators, you should always store them with consumed modifiers removed. Store <Control>plus, not <Control><Shift>plus,.

The function takes the following parameters:

• hardwareKeycode: keycode.
• state: modifier state.
• group: active keyboard group.

The function returns the following values:

• keyval (optional): return location for keyval, or NULL.
• effectiveGroup (optional): return location for effective group, or NULL.
• level (optional): return location for level, or NULL.
• consumedModifiers (optional): return location for modifiers that were used to determine the group or level, or NULL.
• ok: TRUE if there was a keyval bound to the keycode/state/group.

type KeymapKey

type KeymapKey struct {
	// contains filtered or unexported fields
}

KeymapKey is a hardware key that can be mapped to a keyval.

An instance of this type is always passed by reference.

func NewKeymapKey

func NewKeymapKey(keycode uint, group, level int) KeymapKey

NewKeymapKey creates a new KeymapKey instance from the given fields. Beware that this function allocates on the Go heap; be careful when using it!

func (*KeymapKey) Group

func (k *KeymapKey) Group() int

Group indicates movement in a horizontal direction. Usually groups are used for two different languages. In group 0, a key might have two English characters, and in group 1 it might have two Hebrew characters. The Hebrew characters will be printed on the key next to the English characters.

func (*KeymapKey) Keycode

func (k *KeymapKey) Keycode() uint

Keycode: hardware keycode. This is an identifying number for a physical key.

func (*KeymapKey) Level

func (k *KeymapKey) Level() int

Level indicates which symbol on the key will be used, in a vertical direction. So on a standard US keyboard, the key with the number “1” on it also has the exclamation point ("!") character on it. The level indicates whether to use the “1” or the “!” symbol. The letter keys are considered to have a lowercase letter at level 0, and an uppercase letter at level 1, though only the uppercase letter is printed.

func (*KeymapKey) SetGroup

func (k *KeymapKey) SetGroup(group int)

Group indicates movement in a horizontal direction. Usually groups are used for two different languages. In group 0, a key might have two English characters, and in group 1 it might have two Hebrew characters. The Hebrew characters will be printed on the key next to the English characters.

func (*KeymapKey) SetKeycode

func (k *KeymapKey) SetKeycode(keycode uint)

Keycode: hardware keycode. This is an identifying number for a physical key.

func (*KeymapKey) SetLevel

func (k *KeymapKey) SetLevel(level int)

Level indicates which symbol on the key will be used, in a vertical direction. So on a standard US keyboard, the key with the number “1” on it also has the exclamation point ("!") character on it. The level indicates whether to use the “1” or the “!” symbol. The letter keys are considered to have a lowercase letter at level 0, and an uppercase letter at level 1, though only the uppercase letter is printed.

type ModifierIntent

type ModifierIntent C.gint

ModifierIntent: this enum is used with gdk_keymap_get_modifier_mask() in order to determine what modifiers the currently used windowing system backend uses for particular purposes. For example, on X11/Windows, the Control key is used for invoking menu shortcuts (accelerators), whereas on Apple computers it’s the Command key (which correspond to GDK_CONTROL_MASK and GDK_MOD2_MASK, respectively).

const (
	// ModifierIntentPrimaryAccelerator: primary modifier used to invoke menu
	// accelerators.
	ModifierIntentPrimaryAccelerator ModifierIntent = iota
	// ModifierIntentContextMenu: modifier used to invoke context menus. Note
	// that mouse button 3 always triggers context menus. When this modifier is
	// not 0, it additionally triggers context menus when used with mouse button
	// 1.

	// ModifierIntentExtendSelection: modifier used to extend selections using
	// modifier-click or modifier-cursor-key.
	ModifierIntentExtendSelection
	// ModifierIntentModifySelection: modifier used to modify selections,

	// (AltGr on X11/Windows and Option/Alt on OS X).
	ModifierIntentShiftGroup
	// ModifierIntentDefaultModMask: set of modifier masks accepted as
	// modifiers in accelerators. Needed because Command is mapped to
	// MOD2 on OSX, which is widely used, but on X11 MOD2 is NumLock

	// https://bugzilla.gnome.org/show_bug.cgi?id=736125.
	ModifierIntentDefaultModMask
)

func (ModifierIntent) String

func (m ModifierIntent) String() string

String returns the name in string for ModifierIntent.

type ModifierType

type ModifierType C.guint

ModifierType: set of bit-flags to indicate the state of modifier keys and mouse buttons in various event types. Typical modifier keys are Shift, Control, Meta, Super, Hyper, Alt, Compose, Apple, CapsLock or ShiftLock.

Like the X Window System, GDK supports 8 modifier keys and 5 mouse buttons.

Since 2.10, GDK recognizes which of the Meta, Super or Hyper keys are mapped to Mod2 - Mod5, and indicates this by setting GDK_SUPER_MASK, GDK_HYPER_MASK or GDK_META_MASK in the state field of key events.

Note that GDK may add internal values to events which include reserved values such as GDK_MODIFIER_RESERVED_13_MASK. Your code should preserve and ignore them. You can use GDK_MODIFIER_MASK to remove all reserved values.

Also note that the GDK X backend interprets button press events for button 4-7 as scroll events, so GDK_BUTTON4_MASK and GDK_BUTTON5_MASK will never be set.

func (*Seat) Grab

func (seat *Seat) Grab(window Windower, capabilities SeatCapabilities, ownerEvents bool, cursor Cursorrer, event *Event, prepareFunc SeatGrabPrepareFunc) GrabStatus

Grab grabs the seat so that all events corresponding to the given capabilities are passed to this application until the seat is ungrabbed with gdk_seat_ungrab(), or the window becomes hidden. This overrides any previous grab on the seat by this client.

As a rule of thumb, if a grab is desired over GDK_SEAT_CAPABILITY_POINTER, all other "pointing" capabilities (eg. GDK_SEAT_CAPABILITY_TOUCH) should be grabbed too, so the user is able to interact with all of those while the grab holds, you should thus use GDK_SEAT_CAPABILITY_ALL_POINTING most commonly.

Grabs are used for operations which need complete control over the events corresponding to the given capabilities. For example in GTK+ this is used for Drag and Drop operations, popup menus and such.

Note that if the event mask of a Window has selected both button press and button release events, or touch begin and touch end, then a press event will cause an automatic grab until the button is released, equivalent to a grab on the window with owner_events set to TRUE. This is done because most applications expect to receive paired press and release events.

If you set up anything at the time you take the grab that needs to be cleaned up when the grab ends, you should handle the EventGrabBroken events that are emitted when the grab ends unvoluntarily.

The function takes the following parameters:

• window which will own the grab.
• capabilities that will be grabbed.
• ownerEvents: if FALSE then all device events are reported with respect to window and are only reported if selected by event_mask. If TRUE then pointer events for this application are reported as normal, but pointer events outside this application are reported with respect to window and only if selected by event_mask. In either mode, unreported events are discarded.
• cursor (optional) to display while the grab is active. If this is NULL then the normal cursors are used for window and its descendants, and the cursor for window is used elsewhere.
• event (optional) that is triggering the grab, or NULL if none is available.
• prepareFunc (optional): function to prepare the window to be grabbed, it can be NULL if window is visible before this call.

The function returns the following values:

• grabStatus: GDK_GRAB_SUCCESS if the grab was successful.

func (*Window) BeginDrawFrame

func (window *Window) BeginDrawFrame(region *cairo.Region) *DrawingContext

BeginDrawFrame indicates that you are beginning the process of redrawing region on window, and provides you with a DrawingContext.

If window is a top level Window, backed by a native window implementation, a backing store (offscreen buffer) large enough to contain region will be created. The backing store will be initialized with the background color or background surface for window. Then, all drawing operations performed on window will be diverted to the backing store. When you call gdk_window_end_frame(), the contents of the backing store will be copied to window, making it visible on screen. Only the part of window contained in region will be modified; that is, drawing operations are clipped to region.

The net result of all this is to remove flicker, because the user sees the finished product appear all at once when you call gdk_window_end_draw_frame(). If you draw to window directly without calling gdk_window_begin_draw_frame(), the user may see flicker as individual drawing operations are performed in sequence.

When using GTK+, the widget system automatically places calls to gdk_window_begin_draw_frame() and gdk_window_end_draw_frame() around emissions of the GtkWidget::draw signal. That is, if you’re drawing the contents of the widget yourself, you can assume that the widget has a cleared background, is already set as the clip region, and already has a backing store. Therefore in most cases, application code in GTK does not need to call gdk_window_begin_draw_frame() explicitly.

The function takes the following parameters:

• region: cairo region.

The function returns the following values:

• drawingContext context that should be used to draw the contents of the window; the returned context is owned by GDK.

func (*Window) BeginMoveDrag

func (window *Window) BeginMoveDrag(button, rootX, rootY int, timestamp uint32)

BeginMoveDrag begins a window move operation (for a toplevel window).

This function assumes that the drag is controlled by the client pointer device, use gdk_window_begin_move_drag_for_device() to begin a drag with a different device.

The function takes the following parameters:

• button being used to drag, or 0 for a keyboard-initiated drag.
• rootX: root window X coordinate of mouse click that began the drag.
• rootY: root window Y coordinate of mouse click that began the drag.
• timestamp of mouse click that began the drag.

func (*Window) BeginMoveDragForDevice

func (window *Window) BeginMoveDragForDevice(device Devicer, button, rootX, rootY int, timestamp uint32)

BeginMoveDragForDevice begins a window move operation (for a toplevel window). You might use this function to implement a “window move grip,” for example. The function works best with window managers that support the Extended Window Manager Hints (http://www.freedesktop.org/Standards/wm-spec) but has a fallback implementation for other window managers.

The function takes the following parameters:

• device used for the operation.
• button being used to drag, or 0 for a keyboard-initiated drag.
• rootX: root window X coordinate of mouse click that began the drag.
• rootY: root window Y coordinate of mouse click that began the drag.
• timestamp of mouse click that began the drag.

func (*Window) BeginPaintRect

func (window *Window) BeginPaintRect(rectangle *Rectangle)

BeginPaintRect: convenience wrapper around gdk_window_begin_paint_region() which creates a rectangular region for you. See gdk_window_begin_paint_region() for details.

Deprecated: Use gdk_window_begin_draw_frame() instead.

The function takes the following parameters:

• rectangle you intend to draw to.

func (*Window) BeginPaintRegion

func (window *Window) BeginPaintRegion(region *cairo.Region)

BeginPaintRegion indicates that you are beginning the process of redrawing region. A backing store (offscreen buffer) large enough to contain region will be created. The backing store will be initialized with the background color or background surface for window. Then, all drawing operations performed on window will be diverted to the backing store. When you call gdk_window_end_paint(), the backing store will be copied to window, making it visible onscreen. Only the part of window contained in region will be modified; that is, drawing operations are clipped to region.

The net result of all this is to remove flicker, because the user sees the finished product appear all at once when you call gdk_window_end_paint(). If you draw to window directly without calling gdk_window_begin_paint_region(), the user may see flicker as individual drawing operations are performed in sequence. The clipping and background-initializing features of gdk_window_begin_paint_region() are conveniences for the programmer, so you can avoid doing that work yourself.

When using GTK+, the widget system automatically places calls to gdk_window_begin_paint_region() and gdk_window_end_paint() around emissions of the expose_event signal. That is, if you’re writing an expose event handler, you can assume that the exposed area in EventExpose has already been cleared to the window background, is already set as the clip region, and already has a backing store. Therefore in most cases, application code need not call gdk_window_begin_paint_region(). (You can disable the automatic calls around expose events on a widget-by-widget basis by calling gtk_widget_set_double_buffered().)

If you call this function multiple times before calling the matching gdk_window_end_paint(), the backing stores are pushed onto a stack. gdk_window_end_paint() copies the topmost backing store onscreen, subtracts the topmost region from all other regions in the stack, and pops the stack. All drawing operations affect only the topmost backing store in the stack. One matching call to gdk_window_end_paint() is required for each call to gdk_window_begin_paint_region().

Deprecated: Use gdk_window_begin_draw_frame() instead.

The function takes the following parameters:

• region you intend to draw to.

func (*Window) BeginResizeDrag

func (window *Window) BeginResizeDrag(edge WindowEdge, button, rootX, rootY int, timestamp uint32)

BeginResizeDrag begins a window resize operation (for a toplevel window).

This function assumes that the drag is controlled by the client pointer device, use gdk_window_begin_resize_drag_for_device() to begin a drag with a different device.

The function takes the following parameters:

• edge or corner from which the drag is started.
• button being used to drag, or 0 for a keyboard-initiated drag.
• rootX: root window X coordinate of mouse click that began the drag.
• rootY: root window Y coordinate of mouse click that began the drag.
• timestamp of mouse click that began the drag (use gdk_event_get_time()).

func (*Window) BeginResizeDragForDevice

func (window *Window) BeginResizeDragForDevice(edge WindowEdge, device Devicer, button, rootX, rootY int, timestamp uint32)

BeginResizeDragForDevice begins a window resize operation (for a toplevel window). You might use this function to implement a “window resize grip,” for example; in fact Statusbar uses it. The function works best with window managers that support the Extended Window Manager Hints (http://www.freedesktop.org/Standards/wm-spec) but has a fallback implementation for other window managers.

The function takes the following parameters:

• edge or corner from which the drag is started.
• device used for the operation.
• button being used to drag, or 0 for a keyboard-initiated drag.
• rootX: root window X coordinate of mouse click that began the drag.
• rootY: root window Y coordinate of mouse click that began the drag.
• timestamp of mouse click that began the drag (use gdk_event_get_time()).

func (*Window) Children

func (window *Window) Children() []Windower

Children gets the list of children of window known to GDK. This function only returns children created via GDK, so for example it’s useless when used with the root window; it only returns windows an application created itself.

The returned list must be freed, but the elements in the list need not be.

The function returns the following values:

• list: list of child windows inside window.

func (*Window) ChildrenWithUserData

func (window *Window) ChildrenWithUserData(userData unsafe.Pointer) []Windower

ChildrenWithUserData gets the list of children of window known to GDK with a particular user_data set on it.

The returned list must be freed, but the elements in the list need not be.

The list is returned in (relative) stacking order, i.e. the lowest window is first.

The function takes the following parameters:

• userData (optional): user data to look for.

The function returns the following values:

• list: list of child windows inside window.

func (*Window) ClipRegion

func (window *Window) ClipRegion() *cairo.Region

ClipRegion computes the region of a window that potentially can be written to by drawing primitives. This region may not take into account other factors such as if the window is obscured by other windows, but no area outside of this region will be affected by drawing primitives.

The function returns the following values:

• region This must be freed with cairo_region_destroy() when you are done.

func (*Window) Composited

func (window *Window) Composited() bool

Composited determines whether window is composited.

See gdk_window_set_composited().

Deprecated: Compositing is an outdated technology that only ever worked on X11.

The function returns the following values:

• ok: TRUE if the window is composited.

func (*Window) ConfigureFinished

func (window *Window) ConfigureFinished()

ConfigureFinished does nothing, present only for compatiblity.

Deprecated: this function is no longer needed.

func (*Window) ConnectCreateSurface

func (window *Window) ConnectCreateSurface(f func(width, height int) (surface *cairo.Surface)) coreglib.SignalHandle

ConnectCreateSurface signal is emitted when an offscreen window needs its surface (re)created, which happens either when the window is first drawn to, or when the window is being resized. The first signal handler that returns a non-NULL surface will stop any further signal emission, and its surface will be used.

Note that it is not possible to access the window's previous surface from within any callback of this signal. Calling gdk_offscreen_window_get_surface() will lead to a crash.

func (*Window) ConnectMovedToRect

func (window *Window) ConnectMovedToRect(f func(flippedRect, finalRect unsafe.Pointer, flippedX, flippedY bool)) coreglib.SignalHandle

ConnectMovedToRect is emitted when the position of window is finalized after being moved to a destination rectangle.

window might be flipped over the destination rectangle in order to keep it on-screen, in which case flipped_x and flipped_y will be set to TRUE accordingly.

flipped_rect is the ideal position of window after any possible flipping, but before any possible sliding. final_rect is flipped_rect, but possibly translated in the case that flipping is still ineffective in keeping window on-screen.

func (*Window) ConnectPickEmbeddedChild

func (window *Window) ConnectPickEmbeddedChild(f func(x, y float64) (window Windower)) coreglib.SignalHandle

ConnectPickEmbeddedChild signal is emitted to find an embedded child at the given position.

func (*Window) CoordsFromParent

func (window *Window) CoordsFromParent(parentX, parentY float64) (x, y float64)

CoordsFromParent transforms window coordinates from a parent window to a child window, where the parent window is the normal parent as returned by gdk_window_get_parent() for normal windows, and the window's embedder as returned by gdk_offscreen_window_get_embedder() for offscreen windows.

For normal windows, calling this function is equivalent to subtracting the return values of gdk_window_get_position() from the parent coordinates. For offscreen windows however (which can be arbitrarily transformed), this function calls the GdkWindow::from-embedder: signal to translate the coordinates.

You should always use this function when writing generic code that walks down a window hierarchy.

See also: gdk_window_coords_to_parent().

The function takes the following parameters:

• parentX: x coordinate in parent’s coordinate system.
• parentY: y coordinate in parent’s coordinate system.

The function returns the following values:

• x (optional): return location for X coordinate in child’s coordinate system.
• y (optional): return location for Y coordinate in child’s coordinate system.

func (*Window) CoordsToParent

func (window *Window) CoordsToParent(x, y float64) (parentX, parentY float64)

CoordsToParent transforms window coordinates from a child window to its parent window, where the parent window is the normal parent as returned by gdk_window_get_parent() for normal windows, and the window's embedder as returned by gdk_offscreen_window_get_embedder() for offscreen windows.

For normal windows, calling this function is equivalent to adding the return values of gdk_window_get_position() to the child coordinates. For offscreen windows however (which can be arbitrarily transformed), this function calls the GdkWindow::to-embedder: signal to translate the coordinates.

You should always use this function when writing generic code that walks up a window hierarchy.

See also: gdk_window_coords_from_parent().

The function takes the following parameters:

• x: x coordinate in child’s coordinate system.
• y: y coordinate in child’s coordinate system.

The function returns the following values:

• parentX (optional): return location for X coordinate in parent’s coordinate system, or NULL.
• parentY (optional): return location for Y coordinate in parent’s coordinate system, or NULL.

func (*Window) CreateGLContext

func (window *Window) CreateGLContext() (GLContexter, error)

CreateGLContext creates a new GLContext matching the framebuffer format to the visual of the Window. The context is disconnected from any particular window or surface.

If the creation of the GLContext failed, error will be set.

Before using the returned GLContext, you will need to call gdk_gl_context_make_current() or gdk_gl_context_realize().

The function returns the following values:

• glContext: newly created GLContext, or NULL on error.

func (*Window) CreateSimilarImageSurface

func (window *Window) CreateSimilarImageSurface(format cairo.Format, width, height, scale int) *cairo.Surface

CreateSimilarImageSurface: create a new image surface that is efficient to draw on the given window.

Initially the surface contents are all 0 (transparent if contents have transparency, black otherwise.)

The width and height of the new surface are not affected by the scaling factor of the window, or by the scale argument; they are the size of the surface in device pixels. If you wish to create an image surface capable of holding the contents of window you can use:

int scale = gdk_window_get_scale_factor (window);
int width = gdk_window_get_width (window) * scale;
int height = gdk_window_get_height (window) * scale;

// format is set elsewhere
cairo_surface_t *surface =
  gdk_window_create_similar_image_surface (window,
                                           format,
                                           width, height,
                                           scale);

Note that unlike cairo_surface_create_similar_image(), the new surface's device scale is set to scale, or to the scale factor of window if scale is 0.

The function takes the following parameters:

• format for the new surface.
• width of the new surface.
• height of the new surface.
• scale of the new surface, or 0 to use same as window.

The function returns the following values:

• surface: pointer to the newly allocated surface. The caller owns the surface and should call cairo_surface_destroy() when done with it.

  This function always returns a valid pointer, but it will return a pointer to a “nil” surface if other is already in an error state or any other error occurs.

func (*Window) CreateSimilarSurface

func (window *Window) CreateSimilarSurface(content cairo.Content, width, height int) *cairo.Surface

CreateSimilarSurface: create a new surface that is as compatible as possible with the given window. For example the new surface will have the same fallback resolution and font options as window. Generally, the new surface will also use the same backend as window, unless that is not possible for some reason. The type of the returned surface may be examined with cairo_surface_get_type().

Initially the surface contents are all 0 (transparent if contents have transparency, black otherwise.).

The function takes the following parameters:

• content for the new surface.
• width of the new surface.
• height of the new surface.

The function returns the following values:

• surface: pointer to the newly allocated surface. The caller owns the surface and should call cairo_surface_destroy() when done with it.

  This function always returns a valid pointer, but it will return a pointer to a “nil” surface if other is already in an error state or any other error occurs.

func (*Window) Cursor

func (window *Window) Cursor() Cursorrer

Cursor retrieves a Cursor pointer for the cursor currently set on the specified Window, or NULL. If the return value is NULL then there is no custom cursor set on the specified window, and it is using the cursor for its parent window.

The function returns the following values:

• cursor (optional) or NULL. The returned object is owned by the Window and should not be unreferenced directly. Use gdk_window_set_cursor() to unset the cursor of the window.

func (*Window) Decorations

func (window *Window) Decorations() (WMDecoration, bool)

Decorations returns the decorations set on the GdkWindow with gdk_window_set_decorations().

The function returns the following values:

• decorations: window decorations will be written here.
• ok: TRUE if the window has decorations set, FALSE otherwise.

func (*Window) Deiconify

func (window *Window) Deiconify()

Deiconify: attempt to deiconify (unminimize) window. On X11 the window manager may choose to ignore the request to deiconify. When using GTK+, use gtk_window_deiconify() instead of the Window variant. Or better yet, you probably want to use gtk_window_present_with_time(), which raises the window, focuses it, unminimizes it, and puts it on the current desktop.

func (*Window) Destroy

func (window *Window) Destroy()

Destroy destroys the window system resources associated with window and decrements window's reference count. The window system resources for all children of window are also destroyed, but the children’s reference counts are not decremented.

Note that a window will not be destroyed automatically when its reference count reaches zero. You must call this function yourself before that happens.

func (*Window) DeviceCursor

func (window *Window) DeviceCursor(device Devicer) Cursorrer

DeviceCursor retrieves a Cursor pointer for the device currently set on the specified Window, or NULL. If the return value is NULL then there is no custom cursor set on the specified window, and it is using the cursor for its parent window.

The function takes the following parameters:

• device: master, pointer Device.

The function returns the following values:

• cursor (optional) or NULL. The returned object is owned by the Window and should not be unreferenced directly. Use gdk_window_set_cursor() to unset the cursor of the window.

func (*Window) DeviceEvents

func (window *Window) DeviceEvents(device Devicer) EventMask

DeviceEvents returns the event mask for window corresponding to an specific device.

The function takes the following parameters:

• device: Device.

The function returns the following values:

• eventMask: device event mask for window.

func (*Window) DevicePosition

func (window *Window) DevicePosition(device Devicer) (x, y int, mask ModifierType, ret Windower)

DevicePosition obtains the current device position and modifier state. The position is given in coordinates relative to the upper left corner of window.

Use gdk_window_get_device_position_double() if you need subpixel precision.

The function takes the following parameters:

• device: pointer Device to query to.

The function returns the following values:

• x (optional): return location for the X coordinate of device, or NULL.
• y (optional): return location for the Y coordinate of device, or NULL.
• mask (optional): return location for the modifier mask, or NULL.
• ret (optional): window underneath device (as with gdk_device_get_window_at_position()), or NULL if the window is not known to GDK.

func (*Window) DevicePositionDouble

func (window *Window) DevicePositionDouble(device Devicer) (x, y float64, mask ModifierType, ret Windower)

DevicePositionDouble obtains the current device position in doubles and modifier state. The position is given in coordinates relative to the upper left corner of window.

The function takes the following parameters:

• device: pointer Device to query to.

The function returns the following values:

• x (optional): return location for the X coordinate of device, or NULL.
• y (optional): return location for the Y coordinate of device, or NULL.
• mask (optional): return location for the modifier mask, or NULL.
• ret (optional): window underneath device (as with gdk_device_get_window_at_position()), or NULL if the window is not known to GDK.

func (*Window) Display

func (window *Window) Display() *Display

Display gets the Display associated with a Window.

The function returns the following values:

• display associated with window.

func (*Window) DragProtocol

func (window *Window) DragProtocol() (Windower, DragProtocol)

DragProtocol finds out the DND protocol supported by a window.

The function returns the following values:

• target (optional): location of the window where the drop should happen. This may be window or a proxy window, or NULL if window does not support Drag and Drop.
• dragProtocol: supported DND protocol.

func (*Window) EffectiveParent

func (window *Window) EffectiveParent() Windower

EffectiveParent obtains the parent of window, as known to GDK. Works like gdk_window_get_parent() for normal windows, but returns the window’s embedder for offscreen windows.

See also: gdk_offscreen_window_get_embedder().

The function returns the following values:

• ret: effective parent of window.

func (*Window) EffectiveToplevel

func (window *Window) EffectiveToplevel() Windower

EffectiveToplevel gets the toplevel window that’s an ancestor of window.

Works like gdk_window_get_toplevel(), but treats an offscreen window's embedder as its parent, using gdk_window_get_effective_parent().

See also: gdk_offscreen_window_get_embedder().

The function returns the following values:

• ret: effective toplevel window containing window.

func (*Window) EnableSynchronizedConfigure

func (window *Window) EnableSynchronizedConfigure()

EnableSynchronizedConfigure does nothing, present only for compatiblity.

Deprecated: this function is no longer needed.

func (*Window) EndDrawFrame

func (window *Window) EndDrawFrame(context *DrawingContext)

EndDrawFrame indicates that the drawing of the contents of window started with gdk_window_begin_frame() has been completed.

This function will take care of destroying the DrawingContext.

It is an error to call this function without a matching gdk_window_begin_frame() first.

The function takes the following parameters:

• context created by gdk_window_begin_draw_frame().

func (*Window) EndPaint

func (window *Window) EndPaint()

EndPaint indicates that the backing store created by the most recent call to gdk_window_begin_paint_region() should be copied onscreen and deleted, leaving the next-most-recent backing store or no backing store at all as the active paint region. See gdk_window_begin_paint_region() for full details.

It is an error to call this function without a matching gdk_window_begin_paint_region() first.

func (*Window) EnsureNative

func (window *Window) EnsureNative() bool

EnsureNative tries to ensure that there is a window-system native window for this GdkWindow. This may fail in some situations, returning FALSE.

Offscreen window and children of them can never have native windows.

Some backends may not support native child windows.

The function returns the following values:

• ok: TRUE if the window has a native window, FALSE otherwise.

func (*Window) EventCompression

func (window *Window) EventCompression() bool

EventCompression: get the current event compression setting for this window.

The function returns the following values:

• ok: TRUE if motion events will be compressed.

func (*Window) Events

func (window *Window) Events() EventMask

Events gets the event mask for window for all master input devices. See gdk_window_set_events().

The function returns the following values:

• eventMask: event mask for window.

func (*Window) Flush

func (window *Window) Flush()

Flush: this function does nothing.

Deprecated: since version 3.14.

func (*Window) Focus

func (window *Window) Focus(timestamp uint32)

Focus sets keyboard focus to window. In most cases, gtk_window_present_with_time() should be used on a Window, rather than calling this function.

The function takes the following parameters:

• timestamp of the event triggering the window focus.

func (*Window) FocusOnMap

func (window *Window) FocusOnMap() bool

FocusOnMap determines whether or not the desktop environment should be hinted that the window does not want to receive input focus when it is mapped.

The function returns the following values:

• ok: whether or not the window wants to receive input focus when it is mapped.

func (*Window) FrameClock

func (window *Window) FrameClock() FrameClocker

FrameClock gets the frame clock for the window. The frame clock for a window never changes unless the window is reparented to a new toplevel window.

The function returns the following values:

• frameClock: frame clock.

func (*Window) FrameExtents

func (window *Window) FrameExtents() *Rectangle

FrameExtents obtains the bounding box of the window, including window manager titlebar/borders if any. The frame position is given in root window coordinates. To get the position of the window itself (rather than the frame) in root window coordinates, use gdk_window_get_origin().

The function returns the following values:

• rect: rectangle to fill with bounding box of the window frame.

func (*Window) FreezeToplevelUpdatesLibgtkOnly

func (window *Window) FreezeToplevelUpdatesLibgtkOnly()

FreezeToplevelUpdatesLibgtkOnly: temporarily freezes a window and all its descendants such that it won't receive expose events. The window will begin receiving expose events again when gdk_window_thaw_toplevel_updates_libgtk_only() is called. If gdk_window_freeze_toplevel_updates_libgtk_only() has been called more than once, gdk_window_thaw_toplevel_updates_libgtk_only() must be called an equal number of times to begin processing exposes.

This function is not part of the GDK public API and is only for use by GTK+.

Deprecated: This symbol was never meant to be used outside of GTK+.

func (*Window) FreezeUpdates

func (window *Window) FreezeUpdates()

FreezeUpdates: temporarily freezes a window such that it won’t receive expose events. The window will begin receiving expose events again when gdk_window_thaw_updates() is called. If gdk_window_freeze_updates() has been called more than once, gdk_window_thaw_updates() must be called an equal number of times to begin processing exposes.

func (*Window) Fullscreen

func (window *Window) Fullscreen()

Fullscreen moves the window into fullscreen mode. This means the window covers the entire screen and is above any panels or task bars.

If the window was already fullscreen, then this function does nothing.

On X11, asks the window manager to put window in a fullscreen state, if the window manager supports this operation. Not all window managers support this, and some deliberately ignore it or don’t have a concept of “fullscreen”; so you can’t rely on the fullscreenification actually happening. But it will happen with most standard window managers, and GDK makes a best effort to get it to happen.

func (*Window) FullscreenMode

func (window *Window) FullscreenMode() FullscreenMode

FullscreenMode obtains the FullscreenMode of the window.

The function returns the following values:

• fullscreenMode applied to the window when fullscreen.

func (*Window) FullscreenOnMonitor

func (window *Window) FullscreenOnMonitor(monitor int)

FullscreenOnMonitor moves the window into fullscreen mode on the given monitor. This means the window covers the entire screen and is above any panels or task bars.

If the window was already fullscreen, then this function does nothing.

The function takes the following parameters:

• monitor: which monitor to display fullscreen on.

func (*Window) Geometry

func (window *Window) Geometry() (x, y, width, height int)

Geometry: any of the return location arguments to this function may be NULL, if you aren’t interested in getting the value of that field.

The X and Y coordinates returned are relative to the parent window of window, which for toplevels usually means relative to the window decorations (titlebar, etc.) rather than relative to the root window (screen-size background window).

On the X11 platform, the geometry is obtained from the X server, so reflects the latest position of window; this may be out-of-sync with the position of window delivered in the most-recently-processed EventConfigure. gdk_window_get_position() in contrast gets the position from the most recent configure event.

Note: If window is not a toplevel, it is much better to call gdk_window_get_position(), gdk_window_get_width() and gdk_window_get_height() instead, because it avoids the roundtrip to the X server and because these functions support the full 32-bit coordinate space, whereas gdk_window_get_geometry() is restricted to the 16-bit coordinates of X11.

The function returns the following values:

• x (optional): return location for X coordinate of window (relative to its parent).
• y (optional): return location for Y coordinate of window (relative to its parent).
• width (optional): return location for width of window.
• height (optional): return location for height of window.

func (*Window) GeometryChanged

func (window *Window) GeometryChanged()

GeometryChanged: this function informs GDK that the geometry of an embedded offscreen window has changed. This is necessary for GDK to keep track of which offscreen window the pointer is in.

func (*Window) Group

func (window *Window) Group() Windower

Group returns the group leader window for window. See gdk_window_set_group().

The function returns the following values:

• ret: group leader window for window.

func (*Window) HasNative

func (window *Window) HasNative() bool

HasNative checks whether the window has a native window or not. Note that you can use gdk_window_ensure_native() if a native window is needed.

The function returns the following values:

• ok: TRUE if the window has a native window, FALSE otherwise.

func (*Window) Height

func (window *Window) Height() int

Height returns the height of the given window.

On the X11 platform the returned size is the size reported in the most-recently-processed configure event, rather than the current size on the X server.

The function returns the following values:

• gint: height of window.

func (*Window) Hide

func (window *Window) Hide()

Hide: for toplevel windows, withdraws them, so they will no longer be known to the window manager; for all windows, unmaps them, so they won’t be displayed. Normally done automatically as part of gtk_widget_hide().

func (*Window) Iconify

func (window *Window) Iconify()

Iconify asks to iconify (minimize) window. The window manager may choose to ignore the request, but normally will honor it. Using gtk_window_iconify() is preferred, if you have a Window widget.

This function only makes sense when window is a toplevel window.

func (*Window) InputShapeCombineRegion

func (window *Window) InputShapeCombineRegion(shapeRegion *cairo.Region, offsetX, offsetY int)

InputShapeCombineRegion: like gdk_window_shape_combine_region(), but the shape applies only to event handling. Mouse events which happen while the pointer position corresponds to an unset bit in the mask will be passed on the window below window.

An input shape is typically used with RGBA windows. The alpha channel of the window defines which pixels are invisible and allows for nicely antialiased borders, and the input shape controls where the window is “clickable”.

On the X11 platform, this requires version 1.1 of the shape extension.

On the Win32 platform, this functionality is not present and the function does nothing.

The function takes the following parameters:

• shapeRegion: region of window to be non-transparent.
• offsetX: x position of shape_region in window coordinates.
• offsetY: y position of shape_region in window coordinates.

func (*Window) InvalidateMaybeRecurse

func (window *Window) InvalidateMaybeRecurse(region *cairo.Region, childFunc WindowChildFunc)

InvalidateMaybeRecurse adds region to the update area for window. The update area is the region that needs to be redrawn, or “dirty region.” The call gdk_window_process_updates() sends one or more expose events to the window, which together cover the entire update area. An application would normally redraw the contents of window in response to those expose events.

GDK will call gdk_window_process_all_updates() on your behalf whenever your program returns to the main loop and becomes idle, so normally there’s no need to do that manually, you just need to invalidate regions that you know should be redrawn.

The child_func parameter controls whether the region of each child window that intersects region will also be invalidated. Only children for which child_func returns UE will have the area invalidated.

The function takes the following parameters:

• region: #cairo_region_t.
• childFunc (optional): function to use to decide if to recurse to a child, NULL means never recurse.

func (*Window) InvalidateRect

func (window *Window) InvalidateRect(rect *Rectangle, invalidateChildren bool)

InvalidateRect: convenience wrapper around gdk_window_invalidate_region() which invalidates a rectangular region. See gdk_window_invalidate_region() for details.

The function takes the following parameters:

• rect (optional): rectangle to invalidate or NULL to invalidate the whole window.
• invalidateChildren: whether to also invalidate child windows.

func (*Window) InvalidateRegion

func (window *Window) InvalidateRegion(region *cairo.Region, invalidateChildren bool)

InvalidateRegion adds region to the update area for window. The update area is the region that needs to be redrawn, or “dirty region.” The call gdk_window_process_updates() sends one or more expose events to the window, which together cover the entire update area. An application would normally redraw the contents of window in response to those expose events.

GDK will call gdk_window_process_all_updates() on your behalf whenever your program returns to the main loop and becomes idle, so normally there’s no need to do that manually, you just need to invalidate regions that you know should be redrawn.

The invalidate_children parameter controls whether the region of each child window that intersects region will also be invalidated. If FALSE, then the update area for child windows will remain unaffected. See gdk_window_invalidate_maybe_recurse if you need fine grained control over which children are invalidated.

The function takes the following parameters:

• region: #cairo_region_t.
• invalidateChildren: TRUE to also invalidate child windows.

func (*Window) IsDestroyed

func (window *Window) IsDestroyed() bool

IsDestroyed: check to see if a window is destroyed..

The function returns the following values:

• ok: TRUE if the window is destroyed.

func (*Window) IsInputOnly

func (window *Window) IsInputOnly() bool

IsInputOnly determines whether or not the window is an input only window.

The function returns the following values:

• ok: TRUE if window is input only.

func (*Window) IsShaped

func (window *Window) IsShaped() bool

IsShaped determines whether or not the window is shaped.

The function returns the following values:

• ok: TRUE if window is shaped.

func (*Window) IsViewable

func (window *Window) IsViewable() bool

IsViewable: check if the window and all ancestors of the window are mapped. (This is not necessarily "viewable" in the X sense, since we only check as far as we have GDK window parents, not to the root window.).

The function returns the following values:

• ok: TRUE if the window is viewable.

func (*Window) IsVisible

func (window *Window) IsVisible() bool

IsVisible checks whether the window has been mapped (with gdk_window_show() or gdk_window_show_unraised()).

The function returns the following values:

• ok: TRUE if the window is mapped.

func (*Window) Lower

func (window *Window) Lower()

Lower lowers window to the bottom of the Z-order (stacking order), so that other windows with the same parent window appear above window. This is true whether or not the other windows are visible.

If window is a toplevel, the window manager may choose to deny the request to move the window in the Z-order, gdk_window_lower() only requests the restack, does not guarantee it.

Note that gdk_window_show() raises the window again, so don’t call this function before gdk_window_show(). (Try gdk_window_show_unraised().).

func (*Window) MarkPaintFromClip

func (window *Window) MarkPaintFromClip(cr *cairo.Context)

MarkPaintFromClip: if you call this during a paint (e.g. between gdk_window_begin_paint_region() and gdk_window_end_paint() then GDK will mark the current clip region of the window as being drawn. This is required when mixing GL rendering via gdk_cairo_draw_from_gl() and cairo rendering, as otherwise GDK has no way of knowing when something paints over the GL-drawn regions.

This is typically called automatically by GTK+ and you don't need to care about this.

The function takes the following parameters:

• cr: #cairo_t.

func (*Window) Maximize

func (window *Window) Maximize()

Maximize maximizes the window. If the window was already maximized, then this function does nothing.

On X11, asks the window manager to maximize window, if the window manager supports this operation. Not all window managers support this, and some deliberately ignore it or don’t have a concept of “maximized”; so you can’t rely on the maximization actually happening. But it will happen with most standard window managers, and GDK makes a best effort to get it to happen.

On Windows, reliably maximizes the window.

func (*Window) MergeChildInputShapes

func (window *Window) MergeChildInputShapes()

MergeChildInputShapes merges the input shape masks for any child windows into the input shape mask for window. i.e. the union of all input masks for window and its children will become the new input mask for window. See gdk_window_input_shape_combine_region().

This function is distinct from gdk_window_set_child_input_shapes() because it includes window’s input shape mask in the set of shapes to be merged.

func (*Window) MergeChildShapes

func (window *Window) MergeChildShapes()

MergeChildShapes merges the shape masks for any child windows into the shape mask for window. i.e. the union of all masks for window and its children will become the new mask for window. See gdk_window_shape_combine_region().

This function is distinct from gdk_window_set_child_shapes() because it includes window’s shape mask in the set of shapes to be merged.

func (*Window) ModalHint

func (window *Window) ModalHint() bool

ModalHint determines whether or not the window manager is hinted that window has modal behaviour.

The function returns the following values:

• ok: whether or not the window has the modal hint set.

func (*Window) Move

func (window *Window) Move(x, y int)

Move repositions a window relative to its parent window. For toplevel windows, window managers may ignore or modify the move; you should probably use gtk_window_move() on a Window widget anyway, instead of using GDK functions. For child windows, the move will reliably succeed.

If you’re also planning to resize the window, use gdk_window_move_resize() to both move and resize simultaneously, for a nicer visual effect.

The function takes the following parameters:

• x: x coordinate relative to window’s parent.
• y: y coordinate relative to window’s parent.

func (*Window) MoveRegion

func (window *Window) MoveRegion(region *cairo.Region, dx, dy int)

MoveRegion: move the part of window indicated by region by dy pixels in the Y direction and dx pixels in the X direction. The portions of region that not covered by the new position of region are invalidated.

Child windows are not moved.

The function takes the following parameters:

• region to move.
• dx: amount to move in the X direction.
• dy: amount to move in the Y direction.

func (*Window) MoveResize

func (window *Window) MoveResize(x, y, width, height int)

MoveResize: equivalent to calling gdk_window_move() and gdk_window_resize(), except that both operations are performed at once, avoiding strange visual effects. (i.e. the user may be able to see the window first move, then resize, if you don’t use gdk_window_move_resize().).

The function takes the following parameters:

• x: new X position relative to window’s parent.
• y: new Y position relative to window’s parent.
• width: new width.
• height: new height.

func (*Window) MoveToRect

func (window *Window) MoveToRect(rect *Rectangle, rectAnchor, windowAnchor Gravity, anchorHints AnchorHints, rectAnchorDx, rectAnchorDy int)

MoveToRect moves window to rect, aligning their anchor points.

rect is relative to the top-left corner of the window that window is transient for. rect_anchor and window_anchor determine anchor points on rect and window to pin together. rect's anchor point can optionally be offset by rect_anchor_dx and rect_anchor_dy, which is equivalent to offsetting the position of window.

anchor_hints determines how window will be moved if the anchor points cause it to move off-screen. For example, GDK_ANCHOR_FLIP_X will replace GDK_GRAVITY_NORTH_WEST with GDK_GRAVITY_NORTH_EAST and vice versa if window extends beyond the left or right edges of the monitor.

Connect to the Window::moved-to-rect signal to find out how it was actually positioned.

The function takes the following parameters:

• rect: destination Rectangle to align window with.
• rectAnchor: point on rect to align with window's anchor point.
• windowAnchor: point on window to align with rect's anchor point.
• anchorHints: positioning hints to use when limited on space.
• rectAnchorDx: horizontal offset to shift window, i.e. rect's anchor point.
• rectAnchorDy: vertical offset to shift window, i.e. rect's anchor point.

func (*Window) Origin

func (window *Window) Origin() (x, y, gint int)

Origin obtains the position of a window in root window coordinates. (Compare with gdk_window_get_position() and gdk_window_get_geometry() which return the position of a window relative to its parent window.).

The function returns the following values:

• x (optional): return location for X coordinate.
• y (optional): return location for Y coordinate.
• gint: not meaningful, ignore.

func (*Window) Parent

func (window *Window) Parent() Windower

Parent obtains the parent of window, as known to GDK. Does not query the X server; thus this returns the parent as passed to gdk_window_new(), not the actual parent. This should never matter unless you’re using Xlib calls mixed with GDK calls on the X11 platform. It may also matter for toplevel windows, because the window manager may choose to reparent them.

Note that you should use gdk_window_get_effective_parent() when writing generic code that walks up a window hierarchy, because gdk_window_get_parent() will most likely not do what you expect if there are offscreen windows in the hierarchy.

The function returns the following values:

• ret: parent of window.

func (*Window) PassThrough

func (window *Window) PassThrough() bool

PassThrough returns whether input to the window is passed through to the window below.

See gdk_window_set_pass_through() for details.

func (*Window) PeekChildren

func (window *Window) PeekChildren() []Windower

PeekChildren: like gdk_window_get_children(), but does not copy the list of children, so the list does not need to be freed.

The function returns the following values:

• list: a reference to the list of child windows in window.

func (*Window) Pointer

func (window *Window) Pointer() (x, y int, mask ModifierType, ret Windower)

Pointer obtains the current pointer position and modifier state. The position is given in coordinates relative to the upper left corner of window.

Deprecated: Use gdk_window_get_device_position() instead.

The function returns the following values:

• x (optional): return location for X coordinate of pointer or NULL to not return the X coordinate.
• y (optional): return location for Y coordinate of pointer or NULL to not return the Y coordinate.
• mask (optional): return location for modifier mask or NULL to not return the modifier mask.
• ret (optional): window containing the pointer (as with gdk_window_at_pointer()), or NULL if the window containing the pointer isn’t known to GDK.

func (*Window) Position

func (window *Window) Position() (x, y int)

Position obtains the position of the window as reported in the most-recently-processed EventConfigure. Contrast with gdk_window_get_geometry() which queries the X server for the current window position, regardless of which events have been received or processed.

The position coordinates are relative to the window’s parent window.

The function returns the following values:

• x (optional): x coordinate of window.
• y (optional): y coordinate of window.

func (*Window) ProcessUpdates

func (window *Window) ProcessUpdates(updateChildren bool)

ProcessUpdates sends one or more expose events to window. The areas in each expose event will cover the entire update area for the window (see gdk_window_invalidate_region() for details). Normally GDK calls gdk_window_process_all_updates() on your behalf, so there’s no need to call this function unless you want to force expose events to be delivered immediately and synchronously (vs. the usual case, where GDK delivers them in an idle handler). Occasionally this is useful to produce nicer scrolling behavior, for example.

Deprecated: since version 3.22.

The function takes the following parameters:

• updateChildren: whether to also process updates for child windows.

func (*Window) Raise

func (window *Window) Raise()

Raise raises window to the top of the Z-order (stacking order), so that other windows with the same parent window appear below window. This is true whether or not the windows are visible.

If window is a toplevel, the window manager may choose to deny the request to move the window in the Z-order, gdk_window_raise() only requests the restack, does not guarantee it.

func (*Window) RegisterDND

func (window *Window) RegisterDND()

RegisterDND registers a window as a potential drop destination.

func (*Window) Reparent

func (window *Window) Reparent(newParent Windower, x, y int)

Reparent reparents window into the given new_parent. The window being reparented will be unmapped as a side effect.

The function takes the following parameters:

• newParent: new parent to move window into.
• x: x location inside the new parent.
• y: y location inside the new parent.

func (*Window) Resize

func (window *Window) Resize(width, height int)

Resize resizes window; for toplevel windows, asks the window manager to resize the window. The window manager may not allow the resize. When using GTK+, use gtk_window_resize() instead of this low-level GDK function.

Windows may not be resized below 1x1.

If you’re also planning to move the window, use gdk_window_move_resize() to both move and resize simultaneously, for a nicer visual effect.

The function takes the following parameters:

• width: new width of the window.
• height: new height of the window.

func (*Window) Restack

func (window *Window) Restack(sibling Windower, above bool)

Restack changes the position of window in the Z-order (stacking order), so that it is above sibling (if above is TRUE) or below sibling (if above is FALSE).

If sibling is NULL, then this either raises (if above is TRUE) or lowers the window.

If window is a toplevel, the window manager may choose to deny the request to move the window in the Z-order, gdk_window_restack() only requests the restack, does not guarantee it.

The function takes the following parameters:

• sibling (optional) that is a sibling of window, or NULL.
• above: boolean.

func (*Window) RootCoords

func (window *Window) RootCoords(x, y int) (rootX, rootY int)

RootCoords obtains the position of a window position in root window coordinates. This is similar to gdk_window_get_origin() but allows you to pass in any position in the window, not just the origin.

The function takes the following parameters:

• x: x coordinate in window.
• y: y coordinate in window.

The function returns the following values:

• rootX: return location for X coordinate.
• rootY: return location for Y coordinate.

func (*Window) RootOrigin

func (window *Window) RootOrigin() (x, y int)

RootOrigin obtains the top-left corner of the window manager frame in root window coordinates.

The function returns the following values:

• x: return location for X position of window frame.
• y: return location for Y position of window frame.

func (*Window) ScaleFactor

func (window *Window) ScaleFactor() int

ScaleFactor returns the internal scale factor that maps from window coordiantes to the actual device pixels. On traditional systems this is 1, but on very high density outputs this can be a higher value (often 2).

A higher value means that drawing is automatically scaled up to a higher resolution, so any code doing drawing will automatically look nicer. However, if you are supplying pixel-based data the scale value can be used to determine whether to use a pixel resource with higher resolution data.

The scale of a window may change during runtime, if this happens a configure event will be sent to the toplevel window.

The function returns the following values:

• gint: scale factor.

func (*Window) Screen

func (window *Window) Screen() *Screen

Screen gets the Screen associated with a Window.

The function returns the following values:

• screen associated with window.

func (*Window) Scroll

func (window *Window) Scroll(dx, dy int)

Scroll the contents of window, both pixels and children, by the given amount. window itself does not move. Portions of the window that the scroll operation brings in from offscreen areas are invalidated. The invalidated region may be bigger than what would strictly be necessary.

For X11, a minimum area will be invalidated if the window has no subwindows, or if the edges of the window’s parent do not extend beyond the edges of the window. In other cases, a multi-step process is used to scroll the window which may produce temporary visual artifacts and unnecessary invalidations.

The function takes the following parameters:

• dx: amount to scroll in the X direction.
• dy: amount to scroll in the Y direction.

func (*Window) SetAcceptFocus

func (window *Window) SetAcceptFocus(acceptFocus bool)

SetAcceptFocus: setting accept_focus to FALSE hints the desktop environment that the window doesn’t want to receive input focus.

On X, it is the responsibility of the window manager to interpret this hint. ICCCM-compliant window manager usually respect it.

The function takes the following parameters:

• acceptFocus: TRUE if the window should receive input focus.

func (*Window) SetBackground

func (window *Window) SetBackground(color *Color)

SetBackground sets the background color of window.

However, when using GTK+, influence the background of a widget using a style class or CSS — if you’re an application — or with gtk_style_context_set_background() — if you're implementing a custom widget.

Deprecated: Don't use this function.

The function takes the following parameters:

• color: Color.

func (*Window) SetBackgroundPattern

func (window *Window) SetBackgroundPattern(pattern *cairo.Pattern)

SetBackgroundPattern sets the background of window.

A background of NULL means that the window won't have any background. On the X11 backend it's also possible to inherit the background from the parent window using gdk_x11_get_parent_relative_pattern().

The windowing system will normally fill a window with its background when the window is obscured then exposed.

Deprecated: Don't use this function.

The function takes the following parameters:

• pattern (optional) to use, or NULL.

func (*Window) SetBackgroundRGBA

func (window *Window) SetBackgroundRGBA(rgba *RGBA)

SetBackgroundRGBA sets the background color of window.

See also gdk_window_set_background_pattern().

Deprecated: Don't use this function.

The function takes the following parameters:

• rgba: RGBA color.

func (*Window) SetChildInputShapes

func (window *Window) SetChildInputShapes()

SetChildInputShapes sets the input shape mask of window to the union of input shape masks for all children of window, ignoring the input shape mask of window itself. Contrast with gdk_window_merge_child_input_shapes() which includes the input shape mask of window in the masks to be merged.

func (*Window) SetChildShapes

func (window *Window) SetChildShapes()

SetChildShapes sets the shape mask of window to the union of shape masks for all children of window, ignoring the shape mask of window itself. Contrast with gdk_window_merge_child_shapes() which includes the shape mask of window in the masks to be merged.

func (*Window) SetComposited

func (window *Window) SetComposited(composited bool)

SetComposited sets a Window as composited, or unsets it. Composited windows do not automatically have their contents drawn to the screen. Drawing is redirected to an offscreen buffer and an expose event is emitted on the parent of the composited window. It is the responsibility of the parent’s expose handler to manually merge the off-screen content onto the screen in whatever way it sees fit.

It only makes sense for child windows to be composited; see gdk_window_set_opacity() if you need translucent toplevel windows.

An additional effect of this call is that the area of this window is no longer clipped from regions marked for invalidation on its parent. Draws done on the parent window are also no longer clipped by the child.

This call is only supported on some systems (currently, only X11 with new enough Xcomposite and Xdamage extensions). You must call gdk_display_supports_composite() to check if setting a window as composited is supported before attempting to do so.

Deprecated: Compositing is an outdated technology that only ever worked on X11.

The function takes the following parameters:

• composited: TRUE to set the window as composited.

func (*Window) SetCursor

func (window *Window) SetCursor(cursor Cursorrer)

SetCursor sets the default mouse pointer for a Window.

Note that cursor must be for the same display as window.

Use gdk_cursor_new_for_display() or gdk_cursor_new_from_pixbuf() to create the cursor. To make the cursor invisible, use GDK_BLANK_CURSOR. Passing NULL for the cursor argument to gdk_window_set_cursor() means that window will use the cursor of its parent window. Most windows should use this default.

The function takes the following parameters:

• cursor (optional): cursor.

func (*Window) SetDecorations

func (window *Window) SetDecorations(decorations WMDecoration)

SetDecorations: “Decorations” are the features the window manager adds to a toplevel Window. This function sets the traditional Motif window manager hints that tell the window manager which decorations you would like your window to have. Usually you should use gtk_window_set_decorated() on a Window instead of using the GDK function directly.

The decorations argument is the logical OR of the fields in the WMDecoration enumeration. If K_DECOR_ALL is included in the mask, the other bits indicate which decorations should be turned off. If K_DECOR_ALL is not included, then the other bits indicate which decorations should be turned on.

Most window managers honor a decorations hint of 0 to disable all decorations, but very few honor all possible combinations of bits.

The function takes the following parameters:

• decorations: decoration hint mask.

func (*Window) SetDeviceCursor

func (window *Window) SetDeviceCursor(device Devicer, cursor Cursorrer)

SetDeviceCursor sets a specific Cursor for a given device when it gets inside window. Use gdk_cursor_new_for_display() or gdk_cursor_new_from_pixbuf() to create the cursor. To make the cursor invisible, use GDK_BLANK_CURSOR. Passing NULL for the cursor argument to gdk_window_set_cursor() means that window will use the cursor of its parent window. Most windows should use this default.

The function takes the following parameters:

• device: master, pointer Device.
• cursor: Cursor.

func (*Window) SetDeviceEvents

func (window *Window) SetDeviceEvents(device Devicer, eventMask EventMask)

SetDeviceEvents sets the event mask for a given device (Normally a floating device, not attached to any visible pointer) to window. For example, an event mask including K_BUTTON_PRESS_MASK means the window should report button press events. The event mask is the bitwise OR of values from the EventMask enumeration.

See the [input handling overview][event-masks] for details.

The function takes the following parameters:

• device to enable events for.
• eventMask: event mask for window.

func (*Window) SetEventCompression

func (window *Window) SetEventCompression(eventCompression bool)

SetEventCompression determines whether or not extra unprocessed motion events in the event queue can be discarded. If TRUE only the most recent event will be delivered.

Some types of applications, e.g. paint programs, need to see all motion events and will benefit from turning off event compression.

By default, event compression is enabled.

The function takes the following parameters:

• eventCompression: TRUE if motion events should be compressed.

func (*Window) SetEvents

func (window *Window) SetEvents(eventMask EventMask)

SetEvents: event mask for a window determines which events will be reported for that window from all master input devices. For example, an event mask including K_BUTTON_PRESS_MASK means the window should report button press events. The event mask is the bitwise OR of values from the EventMask enumeration.

See the [input handling overview][event-masks] for details.

The function takes the following parameters:

• eventMask: event mask for window.

func (*Window) SetFocusOnMap

func (window *Window) SetFocusOnMap(focusOnMap bool)

SetFocusOnMap: setting focus_on_map to FALSE hints the desktop environment that the window doesn’t want to receive input focus when it is mapped. focus_on_map should be turned off for windows that aren’t triggered interactively (such as popups from network activity).

On X, it is the responsibility of the window manager to interpret this hint. Window managers following the freedesktop.org window manager extension specification should respect it.

The function takes the following parameters:

• focusOnMap: TRUE if the window should receive input focus when mapped.

func (*Window) SetFullscreenMode

func (window *Window) SetFullscreenMode(mode FullscreenMode)

SetFullscreenMode specifies whether the window should span over all monitors (in a multi-head setup) or only the current monitor when in fullscreen mode.

The mode argument is from the FullscreenMode enumeration. If K_FULLSCREEN_ON_ALL_MONITORS is specified, the fullscreen window will span over all monitors from the Screen.

On X11, searches through the list of monitors from the Screen the ones which delimit the 4 edges of the entire Screen and will ask the window manager to span the window over these monitors.

If the XINERAMA extension is not available or not usable, this function has no effect.

Not all window managers support this, so you can’t rely on the fullscreen window to span over the multiple monitors when K_FULLSCREEN_ON_ALL_MONITORS is specified.

The function takes the following parameters:

• mode: fullscreen mode.

func (*Window) SetFunctions

func (window *Window) SetFunctions(functions WMFunction)

SetFunctions sets hints about the window management functions to make available via buttons on the window frame.

On the X backend, this function sets the traditional Motif window manager hint for this purpose. However, few window managers do anything reliable or interesting with this hint. Many ignore it entirely.

The functions argument is the logical OR of values from the WMFunction enumeration. If the bitmask includes K_FUNC_ALL, then the other bits indicate which functions to disable; if it doesn’t include K_FUNC_ALL, it indicates which functions to enable.

The function takes the following parameters:

• functions: bitmask of operations to allow on window.

func (*Window) SetGeometryHints

func (window *Window) SetGeometryHints(geometry *Geometry, geomMask WindowHints)

SetGeometryHints sets the geometry hints for window. Hints flagged in geom_mask are set, hints not flagged in geom_mask are unset. To unset all hints, use a geom_mask of 0 and a geometry of NULL.

This function provides hints to the windowing system about acceptable sizes for a toplevel window. The purpose of this is to constrain user resizing, but the windowing system will typically (but is not required to) also constrain the current size of the window to the provided values and constrain programatic resizing via gdk_window_resize() or gdk_window_move_resize().

Note that on X11, this effect has no effect on windows of type GDK_WINDOW_TEMP or windows where override redirect has been turned on via gdk_window_set_override_redirect() since these windows are not resizable by the user.

Since you can’t count on the windowing system doing the constraints for programmatic resizes, you should generally call gdk_window_constrain_size() yourself to determine appropriate sizes.

The function takes the following parameters:

• geometry hints.
• geomMask: bitmask indicating fields of geometry to pay attention to.

func (*Window) SetGroup

func (window *Window) SetGroup(leader Windower)

SetGroup sets the group leader window for window. By default, GDK sets the group leader for all toplevel windows to a global window implicitly created by GDK. With this function you can override this default.

The group leader window allows the window manager to distinguish all windows that belong to a single application. It may for example allow users to minimize/unminimize all windows belonging to an application at once. You should only set a non-default group window if your application pretends to be multiple applications.

The function takes the following parameters:

• leader (optional): group leader window, or NULL to restore the default group leader window.

func (*Window) SetIconList

func (window *Window) SetIconList(pixbufs []*gdkpixbuf.Pixbuf)

SetIconList sets a list of icons for the window. One of these will be used to represent the window when it has been iconified. The icon is usually shown in an icon box or some sort of task bar. Which icon size is shown depends on the window manager. The window manager can scale the icon but setting several size icons can give better image quality since the window manager may only need to scale the icon by a small amount or not at all.

Note that some platforms don't support window icons.

The function takes the following parameters:

• pixbufs: A list of pixbufs, of different sizes.

func (*Window) SetIconName

func (window *Window) SetIconName(name string)

SetIconName windows may have a name used while minimized, distinct from the name they display in their titlebar. Most of the time this is a bad idea from a user interface standpoint. But you can set such a name with this function, if you like.

After calling this with a non-NULL name, calls to gdk_window_set_title() will not update the icon title.

Using NULL for name unsets the icon title; further calls to gdk_window_set_title() will again update the icon title as well.

Note that some platforms don't support window icons.

The function takes the following parameters:

• name (optional) of window while iconified (minimized).

func (*Window) SetKeepAbove

func (window *Window) SetKeepAbove(setting bool)

SetKeepAbove: set if window must be kept above other windows. If the window was already above, then this function does nothing.

On X11, asks the window manager to keep window above, if the window manager supports this operation. Not all window managers support this, and some deliberately ignore it or don’t have a concept of “keep above”; so you can’t rely on the window being kept above. But it will happen with most standard window managers, and GDK makes a best effort to get it to happen.

The function takes the following parameters:

• setting: whether to keep window above other windows.

func (*Window) SetKeepBelow

func (window *Window) SetKeepBelow(setting bool)

SetKeepBelow: set if window must be kept below other windows. If the window was already below, then this function does nothing.

On X11, asks the window manager to keep window below, if the window manager supports this operation. Not all window managers support this, and some deliberately ignore it or don’t have a concept of “keep below”; so you can’t rely on the window being kept below. But it will happen with most standard window managers, and GDK makes a best effort to get it to happen.

The function takes the following parameters:

• setting: whether to keep window below other windows.

func (*Window) SetModalHint

func (window *Window) SetModalHint(modal bool)

SetModalHint: application can use this hint to tell the window manager that a certain window has modal behaviour. The window manager can use this information to handle modal windows in a special way.

You should only use this on windows for which you have previously called gdk_window_set_transient_for().

The function takes the following parameters:

• modal: TRUE if the window is modal, FALSE otherwise.

func (*Window) SetOpacity

func (window *Window) SetOpacity(opacity float64)

SetOpacity: set window to render as partially transparent, with opacity 0 being fully transparent and 1 fully opaque. (Values of the opacity parameter are clamped to the [0,1] range.)

For toplevel windows this depends on support from the windowing system that may not always be there. For instance, On X11, this works only on X screens with a compositing manager running. On Wayland, there is no per-window opacity value that the compositor would apply. Instead, use gdk_window_set_opaque_region (window, NULL) to tell the compositor that the entire window is (potentially) non-opaque, and draw your content with alpha, or use gtk_widget_set_opacity() to set an overall opacity for your widgets.

For child windows this function only works for non-native windows.

For setting up per-pixel alpha topelevels, see gdk_screen_get_rgba_visual(), and for non-toplevels, see gdk_window_set_composited().

Support for non-toplevel windows was added in 3.8.

The function takes the following parameters:

• opacity: opacity.

func (*Window) SetOpaqueRegion

func (window *Window) SetOpaqueRegion(region *cairo.Region)

SetOpaqueRegion: for optimisation purposes, compositing window managers may like to not draw obscured regions of windows, or turn off blending during for these regions. With RGB windows with no transparency, this is just the shape of the window, but with ARGB32 windows, the compositor does not know what regions of the window are transparent or not.

This function only works for toplevel windows.

GTK+ will update this property automatically if the window background is opaque, as we know where the opaque regions are. If your window background is not opaque, please update this property in your Widget::style-updated handler.

The function takes the following parameters:

• region (optional): region, or NULL.

func (*Window) SetOverrideRedirect

func (window *Window) SetOverrideRedirect(overrideRedirect bool)

SetOverrideRedirect: override redirect window is not under the control of the window manager. This means it won’t have a titlebar, won’t be minimizable, etc. - it will be entirely under the control of the application. The window manager can’t see the override redirect window at all.

Override redirect should only be used for short-lived temporary windows, such as popup menus. Menu uses an override redirect window in its implementation, for example.

The function takes the following parameters:

• overrideRedirect: TRUE if window should be override redirect.

func (*Window) SetPassThrough

func (window *Window) SetPassThrough(passThrough bool)

SetPassThrough sets whether input to the window is passed through to the window below.

The default value of this is FALSE, which means that pointer events that happen inside the window are send first to the window, but if the event is not selected by the event mask then the event is sent to the parent window, and so on up the hierarchy.

If pass_through is TRUE then such pointer events happen as if the window wasn't there at all, and thus will be sent first to any windows below window. This is useful if the window is used in a transparent fashion. In the terminology of the web this would be called "pointer-events: none".

Note that a window with pass_through TRUE can still have a subwindow without pass through, so you can get events on a subset of a window. And in that cases you would get the in-between related events such as the pointer enter/leave events on its way to the destination window.

The function takes the following parameters:

• passThrough: boolean.

func (*Window) SetRole

func (window *Window) SetRole(role string)

SetRole: when using GTK+, typically you should use gtk_window_set_role() instead of this low-level function.

The window manager and session manager use a window’s role to distinguish it from other kinds of window in the same application. When an application is restarted after being saved in a previous session, all windows with the same title and role are treated as interchangeable. So if you have two windows with the same title that should be distinguished for session management purposes, you should set the role on those windows. It doesn’t matter what string you use for the role, as long as you have a different role for each non-interchangeable kind of window.

The function takes the following parameters:

• role: string indicating its role.

func (*Window) SetShadowWidth

func (window *Window) SetShadowWidth(left, right, top, bottom int)

SetShadowWidth: newer GTK+ windows using client-side decorations use extra geometry around their frames for effects like shadows and invisible borders. Window managers that want to maximize windows or snap to edges need to know where the extents of the actual frame lie, so that users don’t feel like windows are snapping against random invisible edges.

Note that this property is automatically updated by GTK+, so this function should only be used by applications which do not use GTK+ to create toplevel windows.

The function takes the following parameters:

• left extent.
• right extent.
• top extent.
• bottom extent.

func (*Window) SetSkipPagerHint

func (window *Window) SetSkipPagerHint(skipsPager bool)

SetSkipPagerHint toggles whether a window should appear in a pager (workspace switcher, or other desktop utility program that displays a small thumbnail representation of the windows on the desktop). If a window’s semantic type as specified with gdk_window_set_type_hint() already fully describes the window, this function should not be called in addition, instead you should allow the window to be treated according to standard policy for its semantic type.

The function takes the following parameters:

• skipsPager: TRUE to skip the pager.

func (*Window) SetSkipTaskbarHint

func (window *Window) SetSkipTaskbarHint(skipsTaskbar bool)

SetSkipTaskbarHint toggles whether a window should appear in a task list or window list. If a window’s semantic type as specified with gdk_window_set_type_hint() already fully describes the window, this function should not be called in addition, instead you should allow the window to be treated according to standard policy for its semantic type.

The function takes the following parameters:

• skipsTaskbar: TRUE to skip the taskbar.

func (*Window) SetSourceEvents

func (window *Window) SetSourceEvents(source InputSource, eventMask EventMask)

SetSourceEvents sets the event mask for any floating device (i.e. not attached to any visible pointer) that has the source defined as source. This event mask will be applied both to currently existing, newly added devices after this call, and devices being attached/detached.

The function takes the following parameters:

• source to define the source class.
• eventMask: event mask for window.

func (*Window) SetStartupID

func (window *Window) SetStartupID(startupId string)

SetStartupID: when using GTK+, typically you should use gtk_window_set_startup_id() instead of this low-level function.

The function takes the following parameters:

• startupId: string with startup-notification identifier.

func (*Window) SetStaticGravities

func (window *Window) SetStaticGravities(useStatic bool) bool

SetStaticGravities: used to set the bit gravity of the given window to static, and flag it so all children get static subwindow gravity. This is used if you are implementing scary features that involve deep knowledge of the windowing system. Don’t worry about it.

Deprecated: static gravities haven't worked on anything but X11 for a long time.

The function takes the following parameters:

• useStatic: TRUE to turn on static gravity.

The function returns the following values:

• ok: FALSE.

func (*Window) SetSupportMultidevice

func (window *Window) SetSupportMultidevice(supportMultidevice bool)

SetSupportMultidevice: this function will enable multidevice features in window.

Multidevice aware windows will need to handle properly multiple, per device enter/leave events, device grabs and grab ownerships.

The function takes the following parameters:

• supportMultidevice: TRUE to enable multidevice support in window.

func (*Window) SetTitle

func (window *Window) SetTitle(title string)

SetTitle sets the title of a toplevel window, to be displayed in the titlebar. If you haven’t explicitly set the icon name for the window (using gdk_window_set_icon_name()), the icon name will be set to title as well. title must be in UTF-8 encoding (as with all user-readable strings in GDK/GTK+). title may not be NULL.

The function takes the following parameters:

• title of window.

func (*Window) SetTransientFor

func (window *Window) SetTransientFor(parent Windower)

SetTransientFor indicates to the window manager that window is a transient dialog associated with the application window parent. This allows the window manager to do things like center window on parent and keep window above parent.

See gtk_window_set_transient_for() if you’re using Window or Dialog.

The function takes the following parameters:

• parent: another toplevel Window.

func (*Window) SetTypeHint

func (window *Window) SetTypeHint(hint WindowTypeHint)

SetTypeHint: application can use this call to provide a hint to the window manager about the functionality of a window. The window manager can use this information when determining the decoration and behaviour of the window.

The hint must be set before the window is mapped.

The function takes the following parameters:

• hint of the function this window will have.

func (*Window) SetUrgencyHint

func (window *Window) SetUrgencyHint(urgent bool)

SetUrgencyHint toggles whether a window needs the user's urgent attention.

The function takes the following parameters:

• urgent: TRUE if the window is urgent.

func (*Window) SetUserData

func (window *Window) SetUserData(userData *coreglib.Object)

SetUserData: for most purposes this function is deprecated in favor of g_object_set_data(). However, for historical reasons GTK+ stores the Widget that owns a Window as user data on the Window. So, custom widget implementations should use this function for that. If GTK+ receives an event for a Window, and the user data for the window is non-NULL, GTK+ will assume the user data is a Widget, and forward the event to that widget.

The function takes the following parameters:

• userData (optional): user data.

func (*Window) ShapeCombineRegion

func (window *Window) ShapeCombineRegion(shapeRegion *cairo.Region, offsetX, offsetY int)

ShapeCombineRegion makes pixels in window outside shape_region be transparent, so that the window may be nonrectangular.

If shape_region is NULL, the shape will be unset, so the whole window will be opaque again. offset_x and offset_y are ignored if shape_region is NULL.

On the X11 platform, this uses an X server extension which is widely available on most common platforms, but not available on very old X servers, and occasionally the implementation will be buggy. On servers without the shape extension, this function will do nothing.

This function works on both toplevel and child windows.

The function takes the following parameters:

• shapeRegion (optional): region of window to be non-transparent.
• offsetX: x position of shape_region in window coordinates.
• offsetY: y position of shape_region in window coordinates.

func (*Window) Show

func (window *Window) Show()

Show: like gdk_window_show_unraised(), but also raises the window to the top of the window stack (moves the window to the front of the Z-order).

This function maps a window so it’s visible onscreen. Its opposite is gdk_window_hide().

When implementing a Widget, you should call this function on the widget's Window as part of the “map” method.

func (*Window) ShowUnraised

func (window *Window) ShowUnraised()

ShowUnraised shows a Window onscreen, but does not modify its stacking order. In contrast, gdk_window_show() will raise the window to the top of the window stack.

On the X11 platform, in Xlib terms, this function calls XMapWindow() (it also updates some internal GDK state, which means that you can’t really use XMapWindow() directly on a GDK window).

func (*Window) ShowWindowMenu

func (window *Window) ShowWindowMenu(event *Event) bool

ShowWindowMenu asks the windowing system to show the window menu. The window menu is the menu shown when right-clicking the titlebar on traditional windows managed by the window manager. This is useful for windows using client-side decorations, activating it with a right-click on the window decorations.

The function takes the following parameters:

• event to show the menu for.

The function returns the following values:

• ok: TRUE if the window menu was shown and FALSE otherwise.

func (*Window) SourceEvents

func (window *Window) SourceEvents(source InputSource) EventMask

SourceEvents returns the event mask for window corresponding to the device class specified by source.

The function takes the following parameters:

• source to define the source class.

The function returns the following values:

• eventMask: source event mask for window.

func (*Window) State

func (window *Window) State() WindowState

State gets the bitwise OR of the currently active window state flags, from the WindowState enumeration.

The function returns the following values:

• windowState: window state bitfield.

func (*Window) Stick

func (window *Window) Stick()

Stick: “Pins” a window such that it’s on all workspaces and does not scroll with viewports, for window managers that have scrollable viewports. (When using Window, gtk_window_stick() may be more useful.)

On the X11 platform, this function depends on window manager support, so may have no effect with many window managers. However, GDK will do the best it can to convince the window manager to stick the window. For window managers that don’t support this operation, there’s nothing you can do to force it to happen.

func (*Window) SupportMultidevice

func (window *Window) SupportMultidevice() bool

SupportMultidevice returns TRUE if the window is aware of the existence of multiple devices.

The function returns the following values:

• ok: TRUE if the window handles multidevice features.

func (*Window) ThawToplevelUpdatesLibgtkOnly

func (window *Window) ThawToplevelUpdatesLibgtkOnly()

ThawToplevelUpdatesLibgtkOnly thaws a window frozen with gdk_window_freeze_toplevel_updates_libgtk_only().

This function is not part of the GDK public API and is only for use by GTK+.

Deprecated: This symbol was never meant to be used outside of GTK+.

func (*Window) ThawUpdates

func (window *Window) ThawUpdates()

ThawUpdates thaws a window frozen with gdk_window_freeze_updates().

func (*Window) Toplevel

func (window *Window) Toplevel() Windower

Toplevel gets the toplevel window that’s an ancestor of window.

Any window type but GDK_WINDOW_CHILD is considered a toplevel window, as is a GDK_WINDOW_CHILD window that has a root window as parent.

Note that you should use gdk_window_get_effective_toplevel() when you want to get to a window’s toplevel as seen on screen, because gdk_window_get_toplevel() will most likely not do what you expect if there are offscreen windows in the hierarchy.

The function returns the following values:

• ret: toplevel window containing window.

func (*Window) TypeHint

func (window *Window) TypeHint() WindowTypeHint

TypeHint: this function returns the type hint set for a window.

The function returns the following values:

• windowTypeHint: type hint set for window.

func (*Window) Unfullscreen

func (window *Window) Unfullscreen()

Unfullscreen moves the window out of fullscreen mode. If the window was not fullscreen, does nothing.

On X11, asks the window manager to move window out of the fullscreen state, if the window manager supports this operation. Not all window managers support this, and some deliberately ignore it or don’t have a concept of “fullscreen”; so you can’t rely on the unfullscreenification actually happening. But it will happen with most standard window managers, and GDK makes a best effort to get it to happen.

func (*Window) Unmaximize

func (window *Window) Unmaximize()

Unmaximize unmaximizes the window. If the window wasn’t maximized, then this function does nothing.

On X11, asks the window manager to unmaximize window, if the window manager supports this operation. Not all window managers support this, and some deliberately ignore it or don’t have a concept of “maximized”; so you can’t rely on the unmaximization actually happening. But it will happen with most standard window managers, and GDK makes a best effort to get it to happen.

On Windows, reliably unmaximizes the window.

func (*Window) Unstick

func (window *Window) Unstick()

Unstick: reverse operation for gdk_window_stick(); see gdk_window_stick(), and gtk_window_unstick().

func (*Window) UpdateArea

func (window *Window) UpdateArea() *cairo.Region

UpdateArea transfers ownership of the update area from window to the caller of the function. That is, after calling this function, window will no longer have an invalid/dirty region; the update area is removed from window and handed to you. If a window has no update area, gdk_window_get_update_area() returns NULL. You are responsible for calling cairo_region_destroy() on the returned region if it’s non-NULL.

The function returns the following values:

• region: update area for window.

func (*Window) UserData

func (window *Window) UserData() unsafe.Pointer

UserData retrieves the user data for window, which is normally the widget that window belongs to. See gdk_window_set_user_data().

The function returns the following values:

• data (optional): return location for user data.

func (*Window) VisibleRegion

func (window *Window) VisibleRegion() *cairo.Region

VisibleRegion computes the region of the window that is potentially visible. This does not necessarily take into account if the window is obscured by other windows, but no area outside of this region is visible.

The function returns the following values:

• region This must be freed with cairo_region_destroy() when you are done.

func (*Window) Visual

func (window *Window) Visual() *Visual

Visual gets the Visual describing the pixel format of window.

The function returns the following values:

• visual: Visual.

func (*Window) Width

func (window *Window) Width() int

Width returns the width of the given window.

On the X11 platform the returned size is the size reported in the most-recently-processed configure event, rather than the current size on the X server.

The function returns the following values:

• gint: width of window.

func (*Window) WindowType

func (window *Window) WindowType() WindowType

WindowType gets the type of the window. See WindowType.

The function returns the following values:

• windowType: type of window.

func (*Window) Withdraw

func (window *Window) Withdraw()

Withdraw withdraws a window (unmaps it and asks the window manager to forget about it). This function is not really useful as gdk_window_hide() automatically withdraws toplevel windows before hiding them.

WindowAttributesType: used to indicate which fields in the WindowAttr struct should be honored. For example, if you filled in the “cursor” and “x” fields of WindowAttr, pass “GDK_WA_X | GDK_WA_CURSOR” to gdk_window_new(). Fields in WindowAttr not covered by a bit in this enum are required; for example, the width/height, wclass, and window_type fields are required, they have no corresponding flag in WindowAttributesType.

const (

	WaTitle WindowAttributesType = 0b10
	// WaX: honor the X coordinate field.
	WaX WindowAttributesType = 0b100

type WindowHints

type WindowHints C.guint

WindowHints: used to indicate which fields of a Geometry struct should be paid attention to. Also, the presence/absence of GDK_HINT_POS, GDK_HINT_USER_POS, and GDK_HINT_USER_SIZE is significant, though they don't directly refer to Geometry fields. GDK_HINT_USER_POS will be set automatically by Window if you call gtk_window_move(). GDK_HINT_USER_POS and GDK_HINT_USER_SIZE should be set if the user specified a size/position using a --geometry command-line argument; gtk_window_parse_geometry() automatically sets these flags.

const (
	// HintPos indicates that the program has positioned the window.
	HintPos WindowHints = 0b1
	// HintMinSize: min size fields are set.
	HintMinSize WindowHints = 0b10
