Hi everyone,
I'm trying to use multiprocessing to avoid Python's GIL but with Tkinter,
instead of running my main function, it spawns new windows. In fact, my fuction
is used everytime I press a specified key, but with multiprocessing I only get
a new window when I hit a key. Does anyone have a
Sorry for my bad english.
Here's my code :
def key(event):
instance = 'Instance'
touche = event.char
instance = multiprocessing.Process(target=player, args=(hitkey,))
instance.start()
def player(hitkey):
winsound.
Well I saw this clause on most of the multiprocessing examples I saw but the
reason it was here wasn't explained so I just ignored it (yeah stupid I know).
I don't think I bypassed anything, at least not on purpose. I'm running on
Windows 7 64 bits.

My full code is :
#Import
from tkinter import *
import wave
import winsound
import multiprocessing
#Initialisation
fenetre=Tk()
frame = Frame(fenetre, width=200, height=100)
instance = 'Instance'
#Fonctions
def key(event):
instance = 'Instance'
hitkey = event.char
instance =
It definetly helped, windows don't pop up anymore, but now it doesn't make any
sound anymore. Could it be because of a local (non-global) variable ?

Yeah I did, but I globalized my variables, I've got only functions, and not
methods, and my clause seems to work so I don't know why it doesn't work.

I thought 'clause' was reffering to the 'if __name__ == "__main__":' thing in
English, but apparently not.
Well except the import and the 'globalization' of my variables, every thing is
idented.

Yeah I'm using MRAB's code, my current code is :
#Initalisation
global event
global hitkey
#Functions
def key(event):
hitkey = event.char
instance = multiprocessing.Process(target=player, args=(hitkey,))
instance.start()
def player(hitkey):
winsound

No, not a new window, but my player function doesn't play any sound anymore.
