UtopiaGio

Only coded and running on Windows OS.

Work is proceeding on Linux OS versions, but help is required to port to MacOS.

UtopiaGio is a Go framework library built on top of the Gio library module. Gio is a cross-platform immediate mode GUI.

The GoApplication class/structure maintains a list of GoWindows and manages the control of the GoWindows and their running threads.

Each GoWindow runs it's own message loop, but it will be possible to send and receive communications over channels between windows.

The framework allows the building of more complex programs without the necessity to access the Gio backend. In turn this means reduced calls to Gio directly, but the ability to write specific Gio routines still remains. It is also possible to use all of the Gio widget classes by encapsulating within the GioObject structure inside the Layout function.

Inheritance is achieved using the new GioObject, and the user interface is provided by the new GioWidget.

New layout methods have been introduced requiring a very small change to the Gio package layout module. The Gio widget module is still used on some of the widgets, but the intention is to move any relevant code for GioWidgets to the internal/widget package.

Access to the underlying OS Screen and Main Window has been provided through the desktop package, making it possible to retrieve position, size and scaling of gio windows. The Pos function has been added to the Gio package, which along with the Size function allows positioning and sizing of the gio window. Also available at run time using GoWindowObj SetPos() and SetSize() functions.

A simple GoMainWindow
    package main

    import (
        ui "github.com/utopiagio/utopia"
    )

    var mainwin *ui.GoWindowObj

    func main() {
        // create application instance before any other objects
        app := ui.GoApplication("GoMainWindowDemo")
	
        // create application window
        mainwin = ui.GoMainWindow("GoMainWindow Demo - UtopiaGio Package")
	
        // set the window layout style to stack widgets vertically
        mainwin.SetLayoutStyle(ui.VFlexBoxLayout)
        mainwin.SetMargin(10,10,10,10)
        mainwin.SetBorder(ui.BorderSingleLine, 2, 10, ui.Color_Blue)
        mainwin.SetPadding(10,10,10,10)
	
        // show the application window
        mainwin.Show()

        // run the application
        app.Run()
    }

Every GoWindowObj uses a main layout to allow the positioning of child controls (GioWidgets). The main layout is accessible through the GoWindowObj.Layout() function.

All child controls are created by passing the parent control as the first parameter.

    lblHello := ui.GoLabel(mainwin.Layout(), "Hello")
GoLayout

Usually the main window will be constructed using multiple layouts to allow the positioning of child controls into regions within the main window.

    ....
    layoutTop := ui.GoHFlexBoxLayout(mainwin.Layout())
    layoutBottom := ui.GoHFlexBoxLayout(mainwin.Layout())
    ....

GoLayout has four possible configurations.

1 GoHBoxLayout aligns the child controls horizontally within the layout. No attempt is made to constrain the child controls to fit within the bounds of the layout control. However if the chid controls exceed the horizontal extents of the layout a horizontal scroll bar will be displayed and the layout can be scrolled.

2 GoVBoxLayout aligns the child controls vertically within the layout. No attempt is made to constrain the child controls to fit within the bounds of the layout control. However if the chid controls exceed the vertical extents of the layout a vertical scroll bar will be displayed and the layout can be scrolled.

3 GoHFlexBoxLayout aligns the child controls horizontally and attempts to constrain the child control widths to fit within the layout.

4 GoVFlexBoxLayout aligns the child controls vertically and attempts to constrain the child control heights to fit within the layout.

The sizing method of each child control is determined by the child control's GoSizePolicy.

All controls (GioWidgets), including layouts, have margin, border and padding (GoMargin ,GoBorder, GoPadding) properties, which can be set at run time. Defaults are provided for controls where possible. These are the main windows layout properties

    ....
    mainwin.SetMargin(10,10,10,10)
    mainwin.SetBorder(ui.BorderSingleLine, 2, 10, ui.Color_Blue)
    mainwin.SetPadding(10,10,10,10)
    ....

Usually the main window will only have padding.

    mainwin.SetPadding(10,10,10,10)

Then to add child layouts to the main window and set parameters

    ....
    layoutTop := ui.GoHFlexBoxLayout(mainwin.Layout())
    layoutTop.SetMargin(0,0,0,0)                          // Same as default layout margin
    layoutTop.SetBorder(ui.BorderSingleLine, 2, 10, ui.Color_Blue)
    layoutTop.SetPadding(10,10,10,10)

    ui.GoSpacer(win.Layout(), 10)                         // Add spacer in between layouts

    layoutBottom := ui.GoHFlexBoxLayout(mainwin.Layout())
    layoutBottom.SetSizePolicy(ui.ExpandingWidth, ui.PreferredHeight)    // GoSizePolicy
    layoutBottom.SetMargin(0,0,0,0)                       // Same as default layout margin
    layoutBottom.SetBorder(ui.BorderSingleLine, 2, 10, ui.Color_Blue)
    layoutBottom.SetPadding(0,0,0,0)
    ....
GoSizePolicy

GioWidget sizing can be controlled using a sizing policy. There are basically six settings available FixedWidth and FixedHeight, PreferredWidth and PreferredHeight, ExpandingWidth and ExpandingHeight.

1 Fixed restrains the widget to its Width and Height parameters.

2 Preferred restrains the widget to the dimensions of its children.

3 Expanding expands the widget to use all the available remaining space.

The default for layouts is ExpandingWidth, ExpandingHeight.

GoTextEdit

Add a GoTextEdit control to the top layout and set its SizePolicy and Font.

    txtPad := ui.GoTextEdit(layoutTop, "Enter text here.")
    txtPad.SetSizePolicy(ui.ExpandingWidth, ui.ExpandingHeight)
    txtPad.SetFont("Go", ui.Regular, ui.Bold)

Notice the parent object layoutTop. This declaration renders the TextEdit as a child of this layout.

GoButton

Add a GoButtonObj to the bottom layout and set its border and padding along with the onClick action function.

    btnClose := ui.GoButton(layoutBottom, "Close")
    btnClose.SetBorder(ui.BorderSingleLine, 1, 6, ui.Color_Blue)
    btnClose.SetPadding(4,4,4,4)
    btnClose.SetOnClick(ActionExit_Clicked)

Notice the parent object layoutBottom. This declaration renders the Button as a child of this layout. Also because the layout has a SizePolicy of ui.PreferredHeight, the layout will size to contain the button object and not expand.

The GoButtonObj also has the default SizePolicy of ui.PreferredWidth and ui.PreferredWidth resulting in a button just big enough to display the caption of the button plus some default padding.

The function ActionExit_Clicked() must be declared outside the package main() function as an external function.

    func ActionExit_Clicked() {
        log.Println("ActionExit_Clicked().......")
        os.Exit(0)
    }

Functions

func Collection added in v0.0.2 

func Collection() []font_gio.FontFace

Regular returns a collection of all available Go font faces.

func ColorToRGB 

func ColorToRGB(color GoColor) (r uint8, g uint8, b uint8)

func DisabledBlend 

func DisabledBlend(c color.NRGBA) (d color.NRGBA)

Disabled blends color towards the luminance and multiplies alpha. Blending towards luminance will desaturate the color. Multiplying alpha blends the color together more with the background.

func HoveredBlend 

func HoveredBlend(c color.NRGBA) (h color.NRGBA)

Hovered blends dark colors towards white, and light colors towards black. It is approximate because it operates in non-linear sRGB space.

func MulAlpha 

func MulAlpha(col color.NRGBA, alpha uint8) color.NRGBA

MulAlpha applies the alpha to the color.

func PaintRect 

func PaintRect(gtx layout_gio.Context, size image.Point, fill GoColor)
