[wxPython] Running wxPython in other thread than main?

wxPython Users

Hello,

I am running wxPython 2.2.0 on winNT with Python 1.5.2.

Is there any way to setup a thread for wxPython with the threading
module other than the main thread?

I have tried to set up a thread which imports wxPython.wx and than
starts the wxApp object. This was indicated in earlier posts.

However, when I try to post events via wxPostEvent the program sometimes
works fine, sometimes it crashes. What might be the problem?

Thanks,

Joerg

AFAIK windows GUI is not thread safe. It must be in main thread.

Please try to make a small sample that duplicates the problem and send it to
me.

If you happen to have more than one CPU give this a try.

import win32process
import win32api
win32process.SetProcessAffinityMask(win32api.GetCurrentProcess(), 1)

My multi threaded app on Win2k crashes when run with more than one CPU.
Unless I limit it to just one.
