Windows GUI Library (wui)

A pure Go library to create native Windows GUIs. This project is a modified and enhanced version of the original gonutz/wui library.

See the online documentation for API details.

Credits

This project is based on the excellent work by gonutz who created the original wui library. We've extended it with additional features and improvements while maintaining compatibility with the original API.

Original library: github.com/gonutz/wui

Self-contained

The former third-party packages are now part of this module, so there are no external dependencies and no network access is needed to build:

github.com/2dprototype/wui/w32 (Win32 bindings, from gonutz/w32 v2, extended)
github.com/2dprototype/wui/check (test helper, from gonutz/check)

New Controls

GroupBox - captioned frame for visually grouping controls
TabControl - tab headers with SetOnChange; show/hide Panels per tab (use ContentBounds() to place them)
StatusBar - bottom status bar, optional multiple parts via SetParts / SetPartText
Window.AddTimer(ms, f) - periodic Timer running on the GUI thread (Start, Stop, SetInterval)
DatePicker - date / long date / time chooser with Value, SetValue, SetOnChange
ColorDialog - system color chooser (SetColor, Execute(parent), Color)
ClipboardText() / SetClipboardText(text) - read and write unicode text on the clipboard

Centering Windows

window.SetCenterOnShow(true) - centers on the screen when shown with Show, and over the parent window when shown with ShowModal
window.Center(), window.CenterOnScreen(), window.CenterOnParent() - center at any time

Examples

The examples folder has one small program for each new feature: group_box, tab_control, status_bar, timer, center_window, clipboard, color_dialog, date_picker, canvas_drawing, canvas_mouse, tree_view, context_menu, tooltip and toolbar. Run one with go run ./examples/timer.

Canvas Drawing (PaintBox)

New Canvas functions, all work inside PaintBox.SetOnPaint:

Strokes: SetStroke(wui.Stroke{Width, Style, Cap, Join}), SetLineWidth, SetLineStyle - width, dash styles (LineDash, LineDot, ...), round/square/flat caps, round/bevel/miter joins. They apply to every outline function (Line, DrawRect, DrawEllipse, Polyline, Arc, DrawPie, ...)
Shapes: DrawRoundRect, FillRoundRect, FillRoundRectOutline, FillRectOutline, FillEllipseOutline, DrawPolygon, FillPolygonOutline, Bezier, Curve (smooth curve through points), SetPixel, Pixel, DrawFocusRect
Helpers: RegularPolygonPoints (triangle, hexagon, ...), StarPoints, Clear
Fills: FillGradientH, FillGradientV, FillRectAlpha (transparent fill)
Images: DrawImageScaled (stretch), DrawImageAlpha (transparency)
Clipping: PushDrawEllipse, PushDrawRoundRect, PushDrawPolygon (undo with PopDrawRegion)
State: Save() / Restore() for stroke, font and clip region
Text: TextRectEllipsis (cuts long text with "...")
Mouse: PaintBox.SetOnMouseDown, SetOnMouseUp, SetOnDoubleClick (with MouseButton); dragging keeps reporting SetOnMouseMove outside the box

More Controls and Features

TreeView / TreeNode - hierarchical list (Add, Selected, SetOnSelect, SetOnDoubleClick, Expand, Collapse, ExpandAll, Remove, Tag)
PopupMenu - context menus; Window.SetContextMenu(menu) and control.SetContextMenu(menu) open on right click, or call menu.Show(window, x, y)
SetToolTip(text) - hover hint, available on every control
ToolBar - NewToolBar(parent, x, y, height) with AddButton and AddSeparator

New examples: canvas_drawing, canvas_mouse, tree_view, context_menu, tooltip, toolbar.

Window Effects, Tray, Colors and Drag and Drop

Drag and drop files: window.SetOnDropFiles(func(files []string, x, y int) {...}), and the same SetOnDropFiles on any control (the innermost control under the mouse gets the files)
Colored text: SetTextColor(color) / SetBackgroundColor(color) (and ResetTextColor, ResetBackgroundColor) on Label, CheckBox, RadioButton, GroupBox, EditLine, TextEdit, ComboBox and the fill of a Panel. Check boxes, radio buttons and group boxes drop visual styles when a text color is set because themed controls ignore it
System tray: NewTrayIcon() with SetToolTip, SetIcon, SetMenu(*PopupMenu), SetOnClick, SetOnDoubleClick, ShowBalloon(title, text, kind); attach it with window.SetTrayIcon(tray). window.SetMinimizeToTray(true), window.SetCloseToTray(true), HideToTray, RestoreFromTray, Quit. The icon comes back by itself when Explorer restarts
Transparent window: SetAlpha(0..255) for opacity, SetTransparentColor(color) / SetTransparent(true) for a color key (pixels in that color are see-through and click-through)
Headless window: SetHeadless(true) (no title bar and border) with SetDragByBackground(true) to move it, SetCornerRadius(px) for rounded corners
More window options: SetTopMost, SetShowInTaskbar, SetMinSize, SetMaxSize

New examples: drag_drop, tray, colored_text, overlay_window.

Minimal Example

This is all the code you need to create a window (which does not do much):

package main

import "github.com/2dprototype/wui"

func main() {
	wui.NewWindow().Show()
}

The Designer

A graphical designer tool is included for visually creating GUIs. It is located at github.com/2dprototype/wui/cmd/designer.

Features

Visual Layout: Drag and drop controls onto a window
Property Editor: Modify control properties in real-time
Live Preview: See your GUI as you build it
Code Generation: Export designs as Go source code
Project Management: Save and load designs as JSON project files
Font Customization: Configure fonts for individual controls
Event Handling: Define event handlers (OnPaint, etc.)
Multiple Controls: Button, Label, CheckBox, RadioButton, Slider, ProgressBar, EditLine, TextEdit, ComboBox, Panel, PaintBox, IntUpDown, FloatUpDown, GroupBox, TabControl, DatePicker, StatusBar
Full support for the new features: color pickers for text/background/key color, window options (transparency, headless via Has Border, corner radius, top most, taskbar, drag move, tray, drop files), OnClick and OnDropFiles event editors, copy / cut / paste / duplicate
Responsive: works on small screens. The toolbox and the property panel hide automatically when the window is narrow (F2 / F3 toggle them, F4 goes back to automatic), both scroll with the mouse wheel, the preview pans with the wheel (Shift for sideways) and project files can be dropped onto the designer to open them

  ]
}

WML: XML Layouts (package wml)

github.com/2dprototype/wui/wml loads window layouts from XML files at run time, similar to QML or XAML. The layout contains data only; events refer to Go functions by name.

<wml version="1">
  <Window Name="main" Title="Login" InnerSize="400,300">
    <EditLine Name="user" Bounds="80,10,300,22"/>
    <Button Text="Login" Bounds="300,260,90,26" OnClick="doLogin"/>
  </Window>
</wml>

type form struct {
	Window *wui.Window   `wml:"main"`
	User   *wui.EditLine `wml:"user"`
}

doc, err := wml.ParseFile("login.xml") // validated, with line and column in errors
var f form
_, err = doc.Build(&f, wml.Handlers{"doLogin": func() { println(f.User.Text()) }})
f.Window.Show()

See wml/README.md for the format reference. go run ./cmd/wmlcheck file.xml validates a layout without opening a window, and examples/wml_login is a complete program.

Installation

go get github.com/2dprototype/wui

Functions ¶

func ClipboardFiles ¶ added in v0.0.5

func ClipboardFiles() (files []string, ok bool)

ClipboardFiles returns the paths of the files that were copied in the file explorer (Ctrl+C on files). ok is false if the clipboard holds no files.

func ClipboardImage ¶ added in v0.0.5

func ClipboardImage() (img image.Image, ok bool)

ClipboardImage returns the picture on the clipboard (24 and 32 bit bitmaps, as put there by screenshots and most programs). ok is false if there is none.

func ClipboardText ¶ added in v0.0.2

func ClipboardText() (text string, ok bool)

ClipboardText returns the text on the system clipboard. ok is false if the clipboard does not contain text.

func EnableDPIAwareness ¶ added in v0.0.5

func EnableDPIAwareness() bool

EnableDPIAwareness tells Windows that the program scales itself on high DPI monitors, so the window is no longer blurry-stretched. Call it once at the start of main, before the first window is created. It uses per monitor v2 awareness where available (Windows 10 1703+) and falls back to system DPI awareness. It returns false if nothing could be set, e.g. because the awareness was already fixed by a manifest.

With DPI awareness on, sizes you give are real pixels. Use Window.Scale to turn design sizes (made for 96 DPI) into pixels, and SetOnDPIChanged to react when the window moves to another monitor.

func Enabled ¶

func Enabled(c EnabledControl) bool

Enabled return true if the given control and all of its parents are enabled. This is different from the control's Enabled() function which only returns the enabled state of the control itself. If it is contained in a disabled parent, c.Enabled() will return true while Enabled(c) will return false.

func InputDialog ¶ added in v0.0.5

func InputDialog(title, prompt, initial string) (text string, ok bool)

InputDialog asks the user for a line of text in a small modal window. parent is not used for placement (the dialog opens over the current top window); it is accepted so calls read naturally. ok is false if the user cancelled.

func SingleInstance ¶ added in v0.0.5

func SingleInstance(name string) bool

SingleInstance returns true for the first process that calls it with the given name and false for every later one. Use it at the start of main to stop a second copy of the program from starting. The name should be unique to your program, e.g. "com.example.myapp".

func Visible ¶

func Visible(c VisibleControl) bool

Visible return true if the given control and all of its parents are visible. This is different from the control's Visible() function which only returns the visibility of the control itself. If it is contained in an invisible parent, c.Visible() will return true while Visible(c) will return false.

Types ¶
