fyne-gui-demo5布局嵌套和标签文本

示例图如下:

package mainimport ("fyne.io/fyne/v2""fyne.io/fyne/v2/app""fyne.io/fyne/v2/container""fyne.io/fyne/v2/widget"
)// Layout 界面ui设计--互斥按钮
func Layout() fyne.CanvasObject {var start *widget.Buttonvar stop *widget.Buttonvar label *widget.Label// 全局的垂直布局var fullBox *fyne.Container// 第一层的水平布局var Box1 *fyne.Container// 第二层的水平布局var Box2 *fyne.Containerstart = widget.NewButton("start", func() {label.SetText("state:start")start.Disable()stop.Enable()})stop = widget.NewButton("stop", func() {label.SetText("state:stop")start.Enable()stop.Disable()})label = widget.NewLabel("")// 按钮的初始状态stop.Disable()// 标签的初始状态label.SetText("state:stop")Box1 = container.NewHBox(label,)Box2 = container.NewHBox(start,stop,)// 垂直布局fullBox = container.NewVBox(Box1,Box2,)return fullBox
}func main() {// 创建程序thisApp := app.New()// 创建窗口对象、传入窗口名w := thisApp.NewWindow("Title")// 设置窗口内容w.SetContent(Layout())// 窗口的显示和运行w.ShowAndRun()
