golang windows 桌面程序库 gui lxn walk

安装依赖：

go get github.com/akavel/rsrc
go get github.com/lxn/win
go get github.com/lxn/walk

代码实例：main.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()
}

创建清单文件 main.manifest

main.manifest 是应用程序配置元数据的清单文件，保存在 main.go 的同级目录下，直接复制即可，没特殊情况不用修改

<?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>

编译运行：

将 main.manifest 生成为 main.syso（只需编译一次，可在其他项目重复使用）

rsrc -manifest main.manifest -o main.syso

编译成独立的 exe 文件

go build

go build -ldflags="-H windowsgui"

双击运行 main.exe文件，无法使用 go run main.go 直接运行
