tkinter中多个窗口的多个窗口大小

Question

我在这里使用代码：Switch between two frames in tkinter作为我的代码的基本框架，现在我有多个框架。我想知道是否可以根据显示的帧大小调整窗口大小。例如，我的初始页面可能是一个小而可爱的300x300窗口，只是显示一个按钮列表，但一旦点击进入另一个页面，窗口就会变为500x500.

在此先感谢！

这里是接受的答案Switch between two frames in tkinter的修改版本。我修改了show_frame方法，以便它也改变窗口的几何形状。

import tkinter as tk # python3 
#import Tkinter as tk # python 

TITLE_FONT = ("Helvetica", 18, "bold") 

class SampleApp(tk.Tk): 

    def __init__(self, *args, **kwargs): 
     tk.Tk.__init__(self, *args, **kwargs) 

     # the container is where we'll stack a bunch of frames 
     # on top of each other, then the one we want visible 
     # will be raised above the others 
     container = tk.Frame(self) 
     container.pack(side="top", fill="both", expand=True) 
     container.grid_rowconfigure(0, weight=1) 
     container.grid_columnconfigure(0, weight=1) 

     self.frames = {} 
     for F,geometry in zip((StartPage, PageOne, PageTwo), ('300x300', '500x500', '800x500')):

      frame = F(parent=container, controller=self) 
      # store the frame and the geometry for this frame 
      self.frames[page_name] = (frame, geometry) 

      # put all of the pages in the same location; 
      # the one on the top of the stacking order 
      # will be the one that is visible. 
      frame.grid(row=0, column=0, sticky="nsew") 

     self.show_frame("StartPage") 

    def show_frame(self, page_name): 
     '''Show a frame for the given page name''' 
     frame, geometry = self.frames[page_name]
