我需要在加载新地图之前清除窗口。但是菜单按钮必须保留。我正在尝试self.frame.destroy（），但它也会杀死我的菜单按钮。基本上我需要清除类Sokoban，但这个类不在类Window中。问题出在 def map1（自我）：和 def map2（自我）：

答案 0 :(得分：2)
代码无法使用的代码非常难以使用，因此我将尝试回答您的菜单按钮必须保留部分示例代码。 基本上你创建了两个框架，一个框架可以清除小部件，第二个框架可以容纳其他小部件和第一个框架。
import tkinter as tk
root = tk.Tk()
root.geometry("300x300")
frame1 = tk.Frame(root)
frame2 = tk.Frame(frame1)
frame1.pack()
frame2.pack()
menubar = tk.Menu(frame1)
menubar.add_command(label="Bring Back!", command=frame2.pack)
menubar.add_command(label="Quit!", command=root.destroy)
tk.Button(frame2, text="Forget only frame2", command=frame2.pack_forget).pack()
tk.Label(frame2, text="Label on frame2").pack()
root.config(menu=menubar)
root.mainloop()
