Display fullscreen mode on Tkinter

Question

How can I make a frame in Tkinter display in fullscreen mode? I saw this code, and it's very useful…:

>>> import Tkinter >>> root = Tkinter.Tk() >>> root.overrideredirect(True) >>> root.geometry("{0}x{1}+0+0".format(root.winfo_screenwidth(), root.winfo_screenheight())) 

…but is it possible to edit the code so that hitting Esc automatically makes the window "Restore down"?

I think this is what you're looking for:

Tk.attributes("-fullscreen", True)  # substitute `Tk` for whatever your `Tk()` object is called 

You can use wm_attributes instead of attributes, too.

Then just bind the escape key and add this to the handler:

Tk.attributes("-fullscreen", False) 

An answer to another question alluded to this (with wm_attributes). So, that's how I found out. But, no one just directly went out and said it was the answer for some reason. So, I figured it was worth posting.

Here's a working example (tested on Xubuntu 14.04) that uses F11 to toggle fullscreen on and off and where escape will turn it off only:

import sys if sys.version_info[0] == 2:  # Just checking your Python version to import Tkinter properly.     from Tkinter import * else:     from tkinter import *   class Fullscreen_Window:      def __init__(self):         self.tk = Tk()         self.tk.attributes('-zoomed', True)  # This just maximizes it so we can see the window. It's nothing to do with fullscreen.         self.frame = Frame(self.tk)         self.frame.pack()         self.state = False         self.tk.bind("<F11>", self.toggle_fullscreen)         self.tk.bind("<Escape>", self.end_fullscreen)      def toggle_fullscreen(self, event=None):         self.state = not self.state  # Just toggling the boolean         self.tk.attributes("-fullscreen", self.state)         return "break"      def end_fullscreen(self, event=None):         self.state = False         self.tk.attributes("-fullscreen", False)         return "break"  if __name__ == '__main__':     w = Fullscreen_Window()     w.tk.mainloop() 

If you want to hide a menu, too, there are only two ways I've found to do that. One is to destroy it. The other is to make a blank menu to switch between.

self.tk.config(menu=self.blank_menu)  # self.blank_menu is a Menu object 

Then switch it back to your menu when you want it to show up again.

self.tk.config(menu=self.menu)  # self.menu is your menu.
