MainLoop starts running event loop on main thread (must be called from the main thread).

func (*App) MonitorChange 

func (a *App) MonitorChange(monitor *glfw.Monitor, event glfw.PeripheralEvent)

MonitorChange is called when a monitor is connected to or disconnected from the system.

func (*App) NewWindow

func (*App) SaveScreenInfo 

func (a *App) SaveScreenInfo(sc *system.Screen) bool

SaveScreenInfo saves a copy of given screen info to screensAll list if unique based on name. Returns true if added a new screen.

func (*App) SendEmptyEvent 

func (a *App) SendEmptyEvent()

SendEmptyEvent sends an empty, blank event to global event processing system, which has the effect of pushing the system along during cases when the event loop needs to be "pinged" to get things moving along..

type Clipboard 

type Clipboard struct{}

Clipboard is the system.Clipboard implementation for Linux

func (*Clipboard) Clear 

func (cl *Clipboard) Clear()

func (*Clipboard) IsEmpty 

func (cl *Clipboard) IsEmpty() bool

func (*Clipboard) Read 

func (cl *Clipboard) Read(types []string) mimedata.Mimes

func (*Clipboard) Write 

func (cl *Clipboard) Write(data mimedata.Mimes) error

type Cursor 

type Cursor struct {
	system.CursorBase

	// Cursors are the cached glfw cursors
	Cursors map[enums.Enum]map[int]*glfw.Cursor

	// Mu is a mutex protecting access to the cursors
	Mu sync.Mutex

	// PrevSize is the cached previous size
	PrevSize int
}

Cursor is the [cursor.Cursor] implementation for the desktop platform

func (*Cursor) Set 

func (cu *Cursor) Set(cursor enums.Enum) error

type Window 

type Window struct {
	base.WindowMulti[*App, *gpudraw.Drawer]

	// Glw is the glfw window associated with this window
	Glw *glfw.Window

	// ScreenName is the name of the last known screen this window was on
	ScreenWindow string
}

Window is the implementation of system.Window for the desktop platform.

func (*Window) Activate 

func (w *Window) Activate() bool

Activate() sets this window as the current render target for gpu rendering functions, and the current context for gpu state (equivalent to MakeCurrentContext on OpenGL). If it returns false, then window is not visible / valid and nothing further should happen. Must call this on app main thread using system.TheApp.RunOnMain 

system.TheApp.RunOnMain(func() {
   if !win.Activate() {
       return
   }
   // do GPU calls here
})

func (*Window) CharEvent 

func (w *Window) CharEvent(gw *glfw.Window, char rune, mod glfw.ModifierKey)

char input

func (*Window) Close 

func (w *Window) Close()

func (*Window) ConstrainFrame added in v0.3.6

func (w *Window) CursorPosEvent(gw *glfw.Window, x, y float64)

func (*Window) DeActivate 

func (w *Window) DeActivate()

DeActivate() clears the current render target and gpu rendering context. Generally more efficient to NOT call this and just be sure to call Activate where relevant, so that if the window is already current context no switching is required. Must call this on app main thread using system.TheApp.RunOnMain

func (*Window) DropEvent 

func (w *Window) DropEvent(gw *glfw.Window, names []string)

func (*Window) FbResized

func (w *Window) Focused(gw *glfw.Window, focused bool)

func (*Window) GetScreenOverlap 

func (w *Window) GetScreenOverlap() *system.Screen

GetScreenOverlap gets the monitor for given window based on overlap of geometry, using limited glfw 3.3 api, which does not provide this functionality. See: https://github.com/glfw/glfw/issues/1699 This is adapted from slawrence2302's code posted there.
