项目采用的是walk技术方案
一、初始化项目
创建一个文件夹比如demo，然后进入demo执行
go mod init demo二、安装walk模块
go get github.com/lxn/walk
go get github.com/lxn/win三、安装rsrc
安装：
go install github.com/akavel/rsrc生成*.syso文件
rsrc -manifest main.manifest -o rsrc.syso四、编写代码
main.go
var logger *log.Logger
var mainWindow *walk.MainWindow
var isLogin boolfunc init() {logger = service.CreateLogService()isLogin = service.CheckLoginStatus(logger)
}
func main() {ui.CreateGUI(logger, mainWindow, isLogin)
}
ui
var loginGUIWidth, loginGUIHeight intfunc init() {loginGUIWidth = 400loginGUIHeight = 100
}func CreateGUI(logger *log.Logger, mw *walk.MainWindow, isLogin bool) {if !isLogin {LoginGUI(logger, mw)} else {MainGUI(logger)}
}func LoginGUI(logger *log.Logger, mw *walk.MainWindow) {var username, password *walk.LineEditmw, err := walk.NewMainWindow()if err != nil {panic(err)logger.Fatalln("LoginUI create error")return}MainWindow{AssignTo: &mw,Title: "登录",Size: Size{Width: loginGUIWidth, Height: loginGUIHeight},Layout: VBox{},Children: []Widget{Composite{Layout: Grid{Columns: 2},Children: []Widget{Label{Text: " 用户名：",},LineEdit{AssignTo: &username,MaxSize: Size{Width: 150, Height: 40},},},},Composite{Layout: Grid{Columns: 2},Children: []Widget{Label{Text: " 密 码：",},LineEdit{AssignTo: &password,MaxSize: Size{Width: 150, Height: 40},PasswordMode: true,},},},Composite{Layout: HBox{},Children: []Widget{PushButton{Text: "登录",MaxSize: Size{Width: 50, Height: 40},OnClicked: func() {flag := service.LoginService(username.Text(), password.Text())if flag {service.SaveLoginStatus(logger)mw.Close()MainGUI(logger)} else {walk.MsgBox(mw, "错误", "用户名或密码错误", walk.MsgBoxIconError)}},},},},},}.Create()setWindowMaxDisable(mw)setWindowSizeDisable(mw)setWindowIcon(logger, mw)setOriginLocation(mw, loginGUIWidth, loginGUIHeight)setSysTray(logger, mw)// setSysNotification(logger, mw, "syscloud", "正在连接中")

}// 设置窗口初始位置
func setOriginLocation(mw *walk.MainWindow, width int, height int) {mw.SetX(int(win.GetSystemMetrics(win.SM_CXSCREEN))/2 - width/2)mw.SetY(int(win.GetSystemMetrics(win.SM_CYSCREEN))/2 - height/2)
}// 设置icon
func setWindowIcon(logger *log.Logger, mw *walk.MainWindow) {icon := getIcon(logger)mw.SetIcon(icon)
}// 获取icon
func getIcon(logger *log.Logger) walk.Image {icon, err := walk.Resources.Image("resource/icon.ico")if err != nil {logger.Println("ERROR:获取icon失败", err)}return icon
}// 设置系统托盘
func setSysTray(logger *log.Logger, mw *walk.MainWindow) {notifyIcon, err := walk.NewNotifyIcon(mw)if nil != err {logger.Println("ERROR:设置提醒图标失败")}defer notifyIcon.Dispose()icon := getIcon(logger)err = notifyIcon.SetIcon(icon)if nil != err {logger.Println("ERROR:设置图标失败")}notifyIcon.SetVisible(true)if err := notifyIcon.SetToolTip("syscloud客户端"); err != nil { // 设置系统托盘悬浮信息logger.Println("ERROR:设置悬浮信息失败", err)}setConnectMenu(logger, notifyIcon)setDisconnectMenu(logger, notifyIcon)setExitMenu(logger, notifyIcon)notifyIcon.ShowInfo("syscloud", "正在连接中")// notifyIcon.ShowInfo("syscloud", "连接成功")mw.Run()
}// 系统托盘右键菜单(退出)
func setExitMenu(logger *log.Logger, ni *walk.NotifyIcon) {exitAction := walk.NewAction()if err := exitAction.SetText("退出"); err != nil {logger.Println(err)}//Exit 实现的功能exitAction.Triggered().Attach(func() { walk.App().Exit(0) })if err := ni.ContextMenu().Actions().Add(exitAction); err != nil {logger.Println(err)}
