python GUI关闭一个框架并打开另一个

Question

我正在编写一个程序，为曲棍球队使用两个类（团队类和联盟类）。图形用户界面正在模拟8支球队的单轮淘汰赛“季后赛”。我希望GUI允许用户输入第一轮4场比赛的比分，然后点击提交按钮。当按下此按钮时，我想弹出一个消息框列出获胜者，然后在该框关闭时关闭原始框架，并弹出第二个输入字段。我真的不确定如何做到这一点。 我有很多代码，所以我没有包含团队和联盟课程的代码，因为我不认为这个问题是必要的，但是如果有人愿意，我可以发布它。

所以基本上，有没有办法关闭帧/改变一个框架的外观到一个新的框架与点击一个按钮？

是的，有一种方法可以改变框架看按钮的方式。任何属性在创建帧（borderwidth，background等）可以设置可以在任何时候使用configure方法来设置：

import Tkinter as tk 
... 
f = tk.Frame(..., background="green", ...) 
... 
f.configure(background="red") 
... 

至于“关闭”的帧 - 帧不能被“关闭“，但您可以使用destroy方法删除它们。这将摧毁框架及其所有子部件：

f.destroy()
