python Tkinter 全屏显示

 #! /usr/bin/env python
 # -*- coding: utf-8 -*-

 import Tkinter as tk

 class FullScreenApp(object):
     def __init__(self, master, **kwargs):
         self.root = master
         # self.tk.attributes('-zoomed', True)  # This just maximizes it so we can see the window. It's nothing to do with fullscreen.
         self.frame = tk.Frame(self.root)
         self.frame.pack()
         self.state = False
         self.root.bind("<F11>", self.toggle_fullscreen)
         self.root.bind("<Escape>", self.end_fullscreen)

     def toggle_fullscreen(self, event=None):
         self.state = not self.state  # Just toggling the boolean
         self.root.attributes("-fullscreen", self.state)
         return "break"

     def end_fullscreen(self, event=None):
         self.state = False
         self.root.attributes("-fullscreen", False)
         return "break"

 root=tk.Tk()
 app=FullScreenApp(root)
 root.mainloop()

应用场景：在使用树莓派的时候，使用的7寸屏，因此当使用的时候，肯定是希望界面能够全屏显示的。
