Tkinter in thread hangs on windows but not on Linux

[Philippe C. Martin]

Hi,

I need to pop-up in a "modless" manner some windows from an existing
Tkinter loop. The following code works OK under Linux: the second window
opens, shows the information, and quits cleanly when destroyed. However,
under windows, I get the second window without the content (so I hang in
run I guess), and both the thread and the calling process hang.

Any clue ?

Thanks
Philippe

This example worked for me on Windows 2000, after inserting

import threading
from Tkinter import *
import ScrolledText


at the top.

Re: Tkinter in thread hangs on windows but not on Linux

Well this is what is on the top of my script:
from Tkinter import *
import threading
from ScrolledText import *

I still hang under XP .... wish I had 2K to test.

I almost sounds like tkinter does not get refresh events anymore.

I'll keep at it

Actually, the following link:

http://www.astro.washington.edu/owen/TkinterSummary.html

seems to say my code is illegal - so I'm now just launching a modless
window from the main thread - _seems_ to work
