[Paraview] Python scripts with PyQt4

[Berk Geveci]

Hi Stefan,

I am afraid what you are trying to do is not supported. I am saying
"not supported" rather than "impossible" because someone smarter than
me may be able to figure it out. We never envisioned it as a use case.
I think you have two choices: use C++ to extend ParaView or use PyQt
from python/pvpython building the GUI from scratch. If you are
interested in the second case, I have some code that shows how to
embed the render window(s) into PyQt widgets.

This program works fine in Python 2.6 but fails in the ParaView python shell. Since I'm new to Qt I don't know where to look for help. Is it even possible to display custom Windows?
