About Walk
==========

Walk is a "Windows Application Library Kit" for the Go Programming Language.

Its primarily useful for Desktop GUI development, but there is some more stuff.

Fork from original module
=========================

This is a fork from the [original module](https://github.com/lxn/walk).

Setup
=====

Make sure you have a working Go installation.
See [Getting Started](http://golang.org/doc/install.html)

##### Note
Walk currently requires Go 1.21 or later.

##### To Install
Now run `go get github.com/tailscale/walk`

Using Walk
==========

A Walk application must always begin with a call to `walk.InitApp()`.

The preferred way to create GUIs with Walk is to use its declarative sub package,
as illustrated in this small example:

##### `test.go`

```go
package main

import (
	"log"
	"strings"

	"github.com/tailscale/walk"
	. "github.com/tailscale/walk/declarative"
)

func main() {
	app, err := walk.InitApp()
		if err != nil {
		log.Fatal(err)
	}

	var inTE, outTE *walk.TextEdit

	MainWindow{
		Title:   "SCREAMO",
		MinSize: Size{600, 400},
		Layout:  VBox{},
		Children: []Widget{
			HSplitter{
				Children: []Widget{
					TextEdit{AssignTo: &inTE},
					TextEdit{AssignTo: &outTE, ReadOnly: true},
				},
			},
			PushButton{
				Text: "SCREAM",
				OnClicked: func() {
					outTE.SetText(strings.ToUpper(inTE.Text()))
				},
			},
		},
	}.Create()

	app.Run()
}
```

##### Create Manifest `test.manifest`

```xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
    <assemblyIdentity version="1.0.0.0" processorArchitecture="*" name="SomeFunkyNameHere" type="win32"/>
    <dependency>
        <dependentAssembly>
            <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="*" publicKeyToken="6595b64144ccf1df" language="*"/>
        </dependentAssembly>
    </dependency>
    <application xmlns="urn:schemas-microsoft-com:asm.v3">
        <windowsSettings>
            <dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2, PerMonitor</dpiAwareness>
            <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">True</dpiAware>
        </windowsSettings>
    </application>
</assembly>
```

Then either compile the manifest using the [rsrc tool](https://github.com/akavel/rsrc), like this:

	go get github.com/akavel/rsrc
	rsrc -manifest test.manifest -o rsrc.syso

or rename the `test.manifest` file to `test.exe.manifest` and distribute it with the application instead.

##### Build app

In the directory containing `test.go` run

	go build
	
To get rid of the cmd window, instead run

	go build -ldflags="-H windowsgui"

##### Run app
	
	test.exe
	
##### Sample Output (Windows 7)

##### More Examples
There are some [examples](examples) that should get you started.

Application Manifest Files
==========================
Walk requires Common Controls 6. This means that you must put an appropriate
application manifest file either next to your executable or embedded as a
resource.

You can copy one of the application manifest files that come with the examples.

To embed a manifest file as a resource, you can use the [rsrc tool](https://github.com/akavel/rsrc).

IMPORTANT: If you don't embed a manifest as a resource, then you should not launch
your executable before the manifest file is in place.
If you do anyway, the program will not run properly. And worse, Windows will not
recognize a manifest file, you later drop next to the executable. To fix this,
rebuild your executable and only launch it with a manifest file in place.

Functions ¶

func AllocWindowClassMessage ¶

func AllocWindowClassMessage(className string) (uint32, error)

AllocWindowClassMessage allocates a user-defined message that is only valid within the context of windows sharing the same window class. It returns ErrWindowClassNotRegistered if className is not registered with walk, or ErrNoMoreMessages if the class's message numbering space is exhausted.

AllocWindowClassMessage must be called from the main goroutine.

func AltDown ¶

func AltDown() bool

func AppDataPath ¶

func AppDataPath() (string, error)

func AppendToWalkInit ¶

func AppendToWalkInit(fn func())

AppendToWalkInit enqueues fn to be executed by walk during InitApp. AppendToWalkInit will panic if called after InitApp has already run.

func CommonAppDataPath ¶

func CommonAppDataPath() (string, error)

func ControlDown ¶

func ControlDown() bool

func DefaultModalPreTranslate ¶

func DefaultModalPreTranslate(m Modal, msg *win.MSG) bool

DefaultModalPreTranslate contains common code that Modals should invoke in order to correctly implement their PreTranslateHandler. m must be the Modal itself, and msg must be the pointer that was passed into m's OnPreTranslate implementation. Its return value must also be returned by the PreTranslateHandler.

func DriveNames ¶

func DriveNames() ([]string, error)

func FormatFloat ¶

func FormatFloat(f float64, prec int) string

func FormatFloatGrouped ¶

func FormatFloatGrouped(f float64, prec int) string

func InitWidget ¶

func InitWidget(widget Widget, parent Window, className string, style, exStyle uint32) error

InitWidget initializes a Widget.

func InitWindow ¶

func InitWindow(window, parent Window, className string, style, exStyle uint32) error

InitWindow initializes a window.

Widgets should be initialized using InitWidget instead.

func InitWrapperWindow ¶

func InitWrapperWindow(window Window) error

InitWrapperWindow initializes a window that wraps (embeds) another window.

Calling this method is necessary, if you want to be able to override the WndProc method of the embedded window. The embedded window should only be used as inseparable part of the wrapper window to avoid undefined behavior.

func IntFrom96DPI ¶

func IntFrom96DPI[I constraints.Integer](value I, dpi int) I

IntFrom96DPI converts from 1/96" units to native pixels.

func IntTo96DPI ¶

func IntTo96DPI[I constraints.Integer](value I, dpi int) I

IntTo96DPI converts from native pixels to 1/96" units.

func LocalAppDataPath ¶

func LocalAppDataPath() (string, error)

func LogErrors ¶

func LogErrors() bool

func MARGINSFrom96DPI ¶

func MARGINSFrom96DPI(value win.MARGINS, dpi int) win.MARGINS

MARGINSFrom96DPI converts from 1/96" units to native pixels.

func MakeARGB ¶

func MakeARGB(a byte, r byte, g byte, b byte) win.ARGB

MakeARGB creates a win.ARGB representing a 32-bit color from alpha, red, green, and blue components.

func MouseWheelEventDelta ¶

func MouseWheelEventDelta(button MouseButton) int

func MouseWheelEventKeyState ¶

func MouseWheelEventKeyState(button MouseButton) int

func MsgBox deprecated

func MsgBox(owner Form, title, message string, style MsgBoxStyle) int

MsgBox shows a simple modal dialog box.

Deprecated: Use TaskDialog instead.

func MustRegisterWindowClass ¶

func MustRegisterWindowClass(className string)

MustRegisterWindowClass registers the specified window class.

MustRegisterWindowClass must be called once for every window type that is not based on any system provided control, before calling InitChildWidget or InitWidget. Calling MustRegisterWindowClass twice with the same className results in a panic.

func MustRegisterWindowClassWithStyle ¶

func MustRegisterWindowClassWithStyle(className string, style uint32)

func MustRegisterWindowClassWithWndProcPtr ¶

func MustRegisterWindowClassWithWndProcPtr(className string, wndProcPtr uintptr)
