Enabling/disabling fullscreen and maximize window with a keypress in Python 3.x

I need to enable/disable fullscreen and maximized window (--zoomed) in Python 3.x using Tkinter. This is my code

from tkinter import *
tk = Tk()

def fullscreen_on(event):
  tk.attributes(--fullscreen, True), repr.event.F11

def fullscreen_off(event):
 tk.attributes(--fullscreen, False), repr.event.Escape


photo = PhotoImage(file="image.GIF")
image_label=Label(tk, image=photo)
image_label.grid(row=0, column=2)


tk.mainloop()

It shows the image, but i can't zoom/enable fullscreen.

You are defining callbacks not binding them to anything in your application. To get a callback to react it needs to be bound to an event (e.g. tk.bind ("<Key>", callback) )

Please have a look on the documentation of event / event-binding.

You can bind the event like shown in this SO question.

What is it you want to do using repr.event.F11 / repr.event.Escape? print something?

Please make sure to fix your indentation.

You can also bind F11 and Escape to your callbacks using

  • tk.bind("<F11>", fullscreen_on)
  • tk.bind("<Escape>", fullscreen_off)
