from tkinter import *
from tkinter import ttk
def forward(event):
print("forward")
def stop(event):
print("stop")
root = Tk()
root.bind("<w>", forward)
root.bind("<KeyRelease-w>", stop)
root.mainloop()
Output when w is held:
forward
Stop
forward
Stop
forward
Stop
forward
Stop
forward
Stop
How do i make it do something like this?
forward
Stop
Or this:
forward
forward
forward
forward
forward
Stop
Im on linux if that helps.

It already kind of does that for me, because of key repeat (on windows). One other option to get what you want is to store the key state in a different place, so key down and key up events only modify the stored state, and if you need to check when it's down you can do something like state.w_pressed

Turning off key repeat seems to fix it, but i dont find this to be an ideal fix, the problem is that key repeat seems to also release the key before triggering it again.

what's your goal with this? If you're trying to detect if the key is held, you need some sort of function called on a timer
stable cipher
I dont understand.

Try replacing <w> with <KeyPress-w>, since ideally you should only subscribe to either <key> or both press and release.

What are you ultimately trying to do?
Call a function when a key is pressed and call another one once its released.

ok ill try

Yo that worked! Thanks :D
stable cipher
just once?
yeah
stable cipher
oh
wide onyx
wouldn't that imply it should call multiple times if held?
stable cipher
wait your right
stable cipher
Yo that worked! Thanks :D
wait it didnt work nvm :(

uhh this isnt the ideal result but it would work for me
wide onyx
That's why I'm trying to ask what exactly you're trying to do
wide onyx
Checking if a key is being held requires a timer
What are you trying to do with these forward/stop functions?
stable cipher
send a signal over a socket to a robot
wide onyx
I don't know much about sockets, but you could create some sort of function that gets called on a "tick", like a frame update you'd have on a game
so let's say this function gets called once per second (or more depending on needs)
You can track which keys are being held by storing them in something like a set, and then each tick, just check which buttons are being held by seeing what's in the set
wide onyx
import tkinter as tk
def tick():
pressed_label['text'] = ' '.join(pressed)
root.after(1000, tick)
def add_pressed(event):
pressed.add(event.keysym)
def remove_pressed(event):
pressed.discard(event.keysym)
pressed = set()
root = tk.Tk()
root.bind_all('<KeyPress>', add_pressed)
root.bind_all('<KeyRelease>', remove_pressed)
pressed_label = tk.Label(font=('consolas', 16))
pressed_label.pack()
root.after(1000, tick)
root.mainloop()
here's a basic implementation you can test
