Change the menu text after clicking it in go fyne systray menu

问题

这是我的系统托盘菜单，我需要在点击“start”按钮后将其更改为“stop”（并将其动作更改为“stop”动作）。

这个问题提到了这个问题，但我找不到“menu1”的refresh()方法。

顺便说一下，我正在macOS Big Sur 11.5.1 (20G80)上进行测试，我的Fyne版本是v2.3.3。

这是我的代码：

  1. package main
  3. import (
  4. 	"fmt"
  6. 	"fyne.io/fyne/v2"
  7. 	"fyne.io/fyne/v2/app"
  8. 	"fyne.io/fyne/v2/driver/desktop"
  9. 	"fyne.io/fyne/v2/widget"
  10. )
  12. var menu1 *fyne.MenuItem
  14. func main() {
  15. 	a := app.New()
  16. 	w := a.NewWindow("SysTray")
  18. 	if desk, ok := a.(desktop.App); ok {
  19. 		menu1 = fyne.NewMenuItem("start", func() {
  20. 			fmt.Println("started")
  22. 			// 在启动后，我将菜单标签更改为“stop”，并将Action更改为stop action，
  23. 			// 但我不知道如何将其更新到系统托盘菜单
  24. 			menu1.Label = "stop"
  25. 			menu1.Action = func() {
  26. 				fmt.Println("stopped")
  27. 			}
  28. 			// MenuItem没有Refresh()方法，只有menu1.ChildMenu有
  29. 			// menu1.ChildMenu.Refresh()
  30. 		})
  32. 		menu2 := fyne.NewMenuItem("menu1", nil)
  33. 		menu2.ChildMenu = fyne.NewMenu("",
  34. 			fyne.NewMenuItem("submenu1", func() {
  35. 				fmt.Println("submenu1")
  36. 			}),
  37. 			fyne.NewMenuItem("submenu2", func() {
  38. 				fmt.Println("submenu2")
  39. 			}),
  40. 		)
  42. 		menu3 := fyne.NewMenuItem("show2", func() {
  43. 			fmt.Println("menu2")
  44. 		})
  46. 		m := fyne.NewMenu("MyApp", menu1, menu2, menu3)
  47. 		desk.SetSystemTrayMenu(m)
  48. 	}
  50. 	w.SetContent(widget.NewLabel("Fyne System Tray"))
  51. 	w.SetCloseIntercept(func() {
  52. 		w.Hide()
  53. 	})
  54. 	w.ShowAndRun()
  55. }

Here is my systray menu, I need to change "start" button to "stop" after clicking it(and change it's action to "stop" action)
在点击go fyne systray菜单后更改菜单文本。

This issue had mentioned about this, but I can not find the refresh() method of "menu1".

BTW, I'm testing it in macOS Big Sur 11.5.1 (20G80), and my Fyne version is v2.3.3

Here's my code

  1. package main

  8. )
  9. var menu1 *fyne.MenuItem
  10. func main() {
  11. a := app.New()
  12. w := a.NewWindow("SysTray")
  13. if desk, ok := a.(desktop.App); ok {
  14. menu1 = fyne.NewMenuItem("start", func() {
  15. fmt.Println("started")
  16. // after started, I change the menu label to "stop" and change the Action to stop action,
  17. // but I don't know how to update this to the system tray menu
  18. menu1.Label = "stop"
  19. menu1.Action = func() {
  20. fmt.Println("stopped")
  21. }
  22. // There is no Refresh() method for MenuItem, only for menu1.ChildMenu
  23. // menu1.ChildMenu.Refresh()
  24. })
  25. menu2 := fyne.NewMenuItem("menu1", nil)
  26. menu2.ChildMenu = fyne.NewMenu("",
  27. fyne.NewMenuItem("submenu1", func() {
  28. fmt.Println("submenu1")
  29. }),
  30. fyne.NewMenuItem("submenu2", func() {

如今在Slack上发布的消息和GitHub问题中提到，你需要调用Menu.Refresh来刷新显示的菜单。
在你上面的代码中，应该是m.Refresh()。

英文:

As was posted on Slack earlier today, and on the GitHub issue, you need to call Menu.Refresh to refresh the menu that is shown.
In your code above that would be m.Refresh().

这是一个正常工作的代码：

  1. package main
  3. import (
  4. 	"fmt"
  6. 	"fyne.io/fyne/v2"
  7. 	"fyne.io/fyne/v2/app"
  8. 	"fyne.io/fyne/v2/driver/desktop"
  9. 	"fyne.io/fyne/v2/widget"
  10. )
  12. var menu1 *fyne.MenuItem
  13. var menu *fyne.Menu
  15. func main() {
  16. 	a := app.New()
  17. 	w := a.NewWindow("SysTray")
  19. 	if desk, ok := a.(desktop.App); ok {
  20. 		menu1 = fyne.NewMenuItem("start", func() {
  21. 			if menu1.Label == "start" {
  22. 				fmt.Println("started")
  23. 				menu1.Label = "stop"
  24. 			} else {
  25. 				fmt.Println("stopped")
  26. 				menu1.Label = "start"
  27. 			}
  28. 			// 更改菜单标签后，使用此方法刷新菜单
  29. 			// menu 是返回的
  30. 			menu.Refresh()
  31. 		})
  33. 		menu2 := fyne.NewMenuItem("menu1", nil)
  34. 		menu2.ChildMenu = fyne.NewMenu("",
  35. 			fyne.NewMenuItem("submenu1", func() {
  36. 				fmt.Println("submenu1")
  37. 			}),
  38. 			fyne.NewMenuItem("submenu2", func() {
  39. 				fmt.Println("submenu2")
  40. 			}),
  41. 		)
  43. 		menu3 := fyne.NewMenuItem("show2", func() {
  44. 			fmt.Println("menu2")
  45. 		})
  47. 		menu = fyne.NewMenu("MyApp", menu1, menu2, menu3)
  49. 		desk.SetSystemTrayMenu(menu)
  50. 	}
  52. 	w.SetContent(widget.NewLabel("Fyne System Tray"))
  53. 	w.SetCloseIntercept(func() {
