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
Walk currently requires Go 1.11.x or later.

##### To Install
Now run `go get github.com/chai2010/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/chai2010/walk"
	. "github.com/chai2010/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()
}
```

##### 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.

CGo Optimizations
=================

The usual default message loop includes calls to win32 API functions, which incurs a decent amount
of runtime overhead coming from Go. As an alternative to this, you may compile Walk using an
optional C implementation of the main message loop, by passing the `walk_use_cgo` build tag:

   go build -tags walk_use_cgo

Functions

func AltDown

func AltDown() bool

func AppDataPath

func AppDataPath() (string, error)

func AppendToWalkInit

func AppendToWalkInit(fn func())

func CommonAppDataPath

func CommonAppDataPath() (string, error)

func ControlDown

func ControlDown() bool

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(value, dpi int) int

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

func IntTo96DPI

func IntTo96DPI(value, dpi int) int

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

func LocalAppDataPath

func LocalAppDataPath() (string, error)

func LogErrors

func LogErrors() bool

func MouseWheelEventDelta

func MouseWheelEventDelta(button MouseButton) int

func MouseWheelEventKeyState

func MouseWheelEventKeyState(button MouseButton) int

func MsgBox

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

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)

func MustRegisterWindowClassWithWndProcPtrAndStyle

func MustRegisterWindowClassWithWndProcPtrAndStyle(className string, wndProcPtr uintptr, style uint32)

func PanicOnError

func PanicOnError() bool

func ParseFloat

func ParseFloat(s string) (float64, error)

func RegistryKeyString

func RegistryKeyString(rootKey *RegistryKey, subKeyPath, valueName string) (value string, err error)

func RegistryKeyUint32

func RegistryKeyUint32(rootKey *RegistryKey, subKeyPath, valueName string) (value uint32, err error)

func SetLogErrors

func SetLogErrors(v bool)

func SetPanicOnError

func SetPanicOnError(v bool)

SetBindingMember sets the member from the model of the ComboBox that is bound to a field of the data source managed by an associated DataBinder.

This is only applicable to walk.ReflectListModel models and simple slices of pointers to struct.

For a model consisting of items of type S, data source field of type T and bindingMember "Foo", this can be one of the following:

A field		Foo T
A method	func (s S) Foo() T
A method	func (s S) Foo() (T, error)

If bindingMember is not a simple member name like "Foo", but a path to a member like "A.B.Foo", members "A" and "B" both must be one of the options mentioned above, but with T having type pointer to struct.

A field		Foo T
A method	func (s S) Foo() T
A method	func (s S) Foo() (T, error)

If displayMember is not a simple member name like "Foo", but a path to a member like "A.B.Foo", members "A" and "B" both must be one of the options mentioned above, but with T having type pointer to struct.
