Python Sleep Function:

[mattyd]

Hello:

I am trying to use the Python Sleep Function via import time; I get results but not the results I am looking for.

What I am trying to do is rather simple and only for visual effect in a Python GUI: Display GIF --> Sleep (pause) 5-seconds --> Display next GUI --> Repeat. Such as:

[B].[/B]
[B].[/B]
[B].[/B]
 
image3 = "pic1.GIF"
photo3 = PhotoImage(file=image3)
 
time.sleep(5)
 
image4 = "pic2.GIF"
photo4 = PhotoImage(file=image4)
 
[B].[/B]
[B].[/B]
[B].[/B]

What seems to happen is that I do note a pause, in this case roughly 5-seconds, but it happens before the GUI appears at all upon the screen; the canvas should display, then 1-by-1 each GIF should appear 5-seconds apart. Instead the pause occurs approximately 5-seconds after I initiate "RUN" and the entire thing is rendered without pause between GIFs

Any, hints, ideas, or direction would be greatly appreciated.

Hi!

You are using Tkinter, right? Try this: after the time.sleep(), update the GUI with e.g. root.update() (if root is your main window).
I'm not sure if other GUI's need this too.
