如何从golang fyne容器中删除对象

import (
    "fyne.io/fyne/v2"
    "fyne.io/fyne/v2/app"
)

func main() {
    myApp := app.New()
    myWindow := myApp.NewWindow("Fyne Container Example")
    // 创建并显示窗口
    myWindow.Show()
}

import (
    "fyne.io/fyne/v2/container"
)

func main() {
    // ...
    content := container.NewVBox()
    myWindow.SetContent(content)
    // ...
}

import (
    "fyne.io/fyne/v2/widget"
)

func main() {
    // ...
    label := widget.NewLabel("Hello, World!")
    content.Add(label)
    // ...
}

func main() {
    // ...
    content.Remove(label)
    // ...
}

package main

import (
    "fyne.io/fyne/v2"
    "fyne.io/fyne/v2/app"
    "fyne.io/fyne/v2/container"
    "fyne.io/fyne/v2/widget"
)

func main() {
    myApp := app.New()
    myWindow := myApp.NewWindow("Fyne Container Example")

    content := container.NewVBox()
    myWindow.SetContent(content)

    label := widget.NewLabel("Hello, World!")
    content.Add(label)

    myWindow.Show()

    // 在需要删除对象的地方
    content.Remove(label)
}
