[vtkusers] GUISupport python wrappers?

Sat Nov 30 13:21:04 EST 2013

Hi

thanks for the feedback. I will update the examples to have the imports done with Pyside in a try/except block.

I can make a request to add the two examples to VTK/Examples/GUI/Qt (or to the Python GUI folder ?) Don’t know what the best place would be ?

I had just assumed from the class name that QVTKRenderWindowInteractor wasn't a Qt widget, and that in order to add VTK to my Qt app I needed a "proper" widget. But seeing EmbedPyQt, I don't think I need that anymore because the segfaults I was experiencing seem to be gone...
