Capture all keypresses of the system with Tkinter-CodePudding

I'm coding a little tool that displays the key presses on the screen with Tkinter, useful for screen recording.

Is there a way to get a listener for all key presses of the system globally with Tkinter? (for every keystroke including F1, CTRL, ..., even when the Tkinter window does not have the focus)

I currently know a solution with pyHook.HookManager(), pythoncom.PumpMessages(), etc. but is there a 100% Tkinter solution?

Indeed, pyhook is only for Python 2, and pyhook3 seems to be abandoned, so I would prefer a built-in Python3 / Tkinter solution for Windows.

You can try:

from tkinter import *
 
def key_press(event):
    key = event.char
    print(f"'{key}' is pressed")
 
root = Tk()
root.geometry('640x480')
root.bind('<Key>', key_press)
mainloop()

As suggested in tkinter using two keys at the same time, you can detect all key pressed at the same time with the following:


history = []
def keyup(e):
    print(e.keycode)
    if  e.keycode in history :
        history.pop(history.index(e.keycode))

        var.set(str(history))

def keydown(e):
    if not e.keycode in history :
        history.append(e.keycode)
        var.set(str(history))

root = Tk()
root.bind("<KeyPress>", keydown)
root.bind("<KeyRelease>", keyup)
