Embed vtk window in a QTabWidget

[Kene Meniru]

Hi:

I know this may not be the right place to post this but I found some other
PyQt questions and I am desperate.

My app is the Window class object below and I am trying to embed a
QVTKRenderWindowInteractor class called ConeWindow in its QTabWidget. First
of all running ConeWindow gives out QPainter::begin:, QPainter::save:,
QPainter::setClipRegion:, and QPainter::restore: messages. This may be what
is crashing the Window class when I embed it.

Can somebody help me here? Thanks.
