[vtkusers] Embed QVTKRenderWindowInteractor in a QTabWidget

[Kene Meniru]

Hi: 

My app is the Window class object below and I am trying to embed a 
QVTKRenderWindowInteractor class called ConeWindow below in its QTabWidget. 

First, running ConeWindow alone gives out QPainter::begin:, QPainter::save:, 
QPainter::setClipRegion:, and QPainter::restore: messages. I can't seem to 
stop these messages and it may be what is crashing the Window class when I 
embed it.

Can somebody help me here? Thanks.
