我的建议是如果你想回到主页，那么你不应该破坏框架或小部件，相反，你应该使用
place_forget()或@987654323隐藏框架@ 或grid_forget()如果您分别使用过.place,.pack或.grid -
你没有提供
back_menu -
我希望函数“def openMenu(self):”在我按下此按钮时运行“self.back_button2 = Button(self.myFrame4, image = self.back_menu, command = self.openMenu, bd = 0)" 我不是已经这样做了吗？它可以工作并将我带回主页，但主页外观看起来像我在帖子中发送的第三张图片，我希望它看起来像第一张图片。

我不明白你为什么要破坏框架。你应该使用
pack_forget()而不是for widget in root.winfo_children()和widget.destroy()然后frame.destroy() -
从
self.self.myFrame2 = Frame(root, bg = '')中删除bg = ''。
