Transparent background #782

How can I set the background to be `transparent? The following is not working

func runApp() {
    mw := new(MyMainWindow)
    MainWindow{
        Title:    "Transparent Background",
        Visible:  false,
        MinSize:  Size{800, 600},
        Layout:   VBox{MarginsZero: true},
        AssignTo: &mw.MainWindow,
        Functions: map[string]func(args ...interface{}) (interface{}, error){
            "icon": func(args ...interface{}) (interface{}, error) {
                if strings.HasPrefix(args[0].(string), "https") {
                    return "check", nil
                }

                return "stop", nil
            },
        },
    }.Create()

    win.SetBkMode(win.HDC(mw.Handle()), win.TRANSPARENT
    win.ShowWindow(mw.Handle(), win.SW_SHOW)
    mw.Run()
}
