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

Here is my systray menu, I need to change "start" button to "stop" after clicking it(and change it's action to "stop" action)
enter image description here

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

package main

import (
    "fmt"

    "fyne.io/fyne/v2"
    "fyne.io/fyne/v2/app"
    "fyne.io/fyne/v2/driver/desktop"
    "fyne.io/fyne/v2/widget"
)

var menu1 *fyne.MenuItem

func main() {
    a := app.New()
    w := a.NewWindow("SysTray")

    if desk, ok := a.(desktop.App); ok {
        menu1 = fyne.NewMenuItem("start", func() {
            fmt.Println("started")

            // after started, I change the menu label to "stop" and change the Action to stop action,
            // but I don't know how to update this to the system tray menu
            menu1.Label = "stop"
            menu1.Action = func() {
                fmt.Println("stopped")
            }
            // There is no Refresh() method for MenuItem, only for menu1.ChildMenu
            // menu1.ChildMenu.Refresh()
        })

        menu2 := fyne.NewMenuItem("menu1", nil)
        menu2.ChildMenu = fyne.NewMenu("",
            fyne.NewMenuItem("submenu1", func() {
                fmt.Println("submenu1")
            }),
            fyne.NewMenuItem("submenu2", func() {
                fmt.Println("submenu2")
            }),
        )

        menu3 := fyne.NewMenuItem("show2", func() {
            fmt.Println("menu2")
        })

        m := fyne.NewMenu("MyApp", menu1, menu2, menu3)
        desk.SetSystemTrayMenu(m)
    }

    w.SetContent(widget.NewLabel("Fyne System Tray"))
    w.SetCloseIntercept(func() {
        w.Hide()
    })
    w.ShowAndRun()
}

Here's my go.mod

module go-GUI

go 1.19

Solution

  • 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().
