I'm trying to check if the key "q" is pressed whilst running a tkinter loop. Is there a way to do this?

from tkinter import *
import keyboard

def DetectKeyPress():
     if keyboard.read_key() == "p":
         print("you pressed p!")

root = Tk()
DetectKeyPress()
root.mainloop()

CodePudding user response：

Focused tkinter window

To detect if a key is pressed you can use root.bind('', function). Please be aware that pressing shift and some other keys do count as an independent event.

from tkinter import *


def detect_key_press(event):
    if event.char == "p":
         print("you pressed p!")


root = Tk()
root.bind('<Key>', detect_key_press)
root.mainloop()

Not focused

To detect if a key is pressed while the window is not focused, you have to use keyboard (pip3 install keyboard). On Linux, this requires sudo privileges.

import keyboard

keyboard.add_hotkey('p', print, args=('you pressed p!',))
keyboard.wait('esc')
