#80678 — Synchronizing a sound with a widget change

Hello, here is a small test code:

----------------
from tkinter import Tk, Frame
from winsound import Beep

root = Tk()

f = Frame(root, width=300, height=300)
f.pack()

f.config(bg='Yellow')
Beep(2000, 1000)
--------------

I intended to change the frame color to yellow (f.config(bg='Yellow'))
and at the same time to emit a sound (Beep(2000, 1000))

But I first have the sound and when the sound is over the window appears.

Is there a way to fix that ?

I have the idea to run an other thread to emit the sound, but I didn't try yet.
Is it the solution ?

Thanks

nope, still doesn't work !

from tkinter import Tk, Frame
from winsound import Beep

def mybeep():
    Beep(2000, 1000)

root = Tk()

f = Frame(root, width=300, height=300)
f.pack()

f.config(bg='Yellow')
root.after(1, mybeep)

with:

f = Frame(root, width=300, height=300)
f.pack()
f.config(bg='Yellow')
root.after(80, mybeep)

it works and with:

f = Frame(root, width=300, height=300)
f.pack()
f.config(bg='Yellow')
root.after(60, mybeep)

it doesn't work

I understand that Python takes times to create the root
window and to color the frame. It the sound arrives
before the end of the drawing, Python goes to the sound
emitting,and when finished it goes back to drawing.

This is annoying
I would like sometuhing stable if possible

thx

I don't use Windows, but from what I read,  winsound.Beep is a
 blocking call, and therefore must not be used in the main thread
 of a gui environment. 
Once the function is called, no events are
 processed. 


It seems like you need winsound.SND_ASYNC

Yes, you are right.
I have to use winsound.PlaySound(sound, flags)
with flag = winsound.SND_ASYNC

Hi,

You may try to add the sleep(5) after the color change statement. You could adjust the sleep time to let the color change and beep synchroize.

Thanks.

But sleep () doesn't have a non blocking version. You'd have to
 put it in another thread to get it out of the way.
