Hello NGs,
after the releases of wxPython 2.5 and above, wxVTKRWI stopped to work
with my wxPython application. Now, after the good job that Charles has done
on wxVTKThings, I was expecting no problems. However, now wxPython has stopped
to work with VTK.
I keep getting Windows error with the big red cross announcing that python.exe
has crashed due to some internal error etc etc etc...
It is highly probable that I am doing some stupid mistake, but my app is
becoming quite huge (about 50000 lines of code), and it is more and more
difficult to find such errors. I have however reduced the problem on a small
sample, that I attach at the end of the mail.
My configuration:
1) Windows 2000/XP
2) Python 2.3.4/2.3.5
3) wxPython 2.6.1.0
4) VTK from yesterday's CVS compiled with MSVC 7 .NET or NMake
I will really appreciate every comment/suggestion.
Thank you a lot.
Andrea.

Hi there Andrea,
after the releases of wxPython 2.5 and above, wxVTKRWI stopped to work
with my wxPython application. Now, after the good job that Charles has done

to work with VTK.

It's great that you made a small sample... I can reproduce the crash
on my Windows laptop. It shouldn't crash, but the reason that it's
doing this is because you're explicitly calling Render()s BEFORE the
window has been displayed. If you remove the Render()s that get
called as part of your initialisation before you've Show()n any
windows, it seems to work (except that actors disappear, but I believe
that's another problem altogether).
My advice would be to follow the sequence of actions in the NEW
wxVTKRWI embedded example. Especially look at the way that the
wxVTKRWI is now in a toplevel sizer.
At the moment I'm swamped with work, but I'll look at making
pre-Show() Render()s safe ASAP.
Good luck,
Charl
