[pygtk] win32 filechooser

[LH]

I'm trying to use a native win32 file chooser dialog in a PyGTK
application on Windows. I've followed example 21.13 on the FAQ, which
mostly works. My problem is that while the win32 file chooser is
showing, no PyGTK windows get repainted, no timeouts run, etc. I found
this earlier post on the issue:

I haven't been able to get a win32 timer working to periodically run GTK
main loop iterations, and John mentions that he knew how it was done
from C but not Python. Does anyone have an example of how to do this, or
is there another approach that would refresh PyGTK windows while a win32
file chooser is showing?

Thanks,

Lloyd.
