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.

Setup
=====

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

##### Note
`Go 1.7.x` doesn't work with walk anymore, Make sure you use `Go 1.8.x` or later.

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

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

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 (
	"github.com/lxn/walk"
	. "github.com/lxn/walk/declarative"
	"strings"
)

func main() {
	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()))
				},
			},
		},
	}.Run()
}
```

##### 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.

Program Crashes
===============
By default Go uses os threads with small stack sizes of 128KB. If your walk app crashes, it may be due
to a stack overflow. Until a [better solution is found](https://github.com/golang/go/issues/20975),
you can work around this by adding

    import _ "runtime/cgo"

somewhere in your program. If you don't have `gcc` installed and on your `PATH`,
you can alternatively add `-linkmode internal` to the `-ldflags` of your `go build` command like so:

    go build -ldflags="-H windowsgui -linkmode internal"

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.
