Alright, I see. Would you mind sharing how you handle custom interactions
with a VTK rendering, if you don't use the interactor styles?
Do you directly observe events on the interactor instead? Or do you simply
handle the Qt events directly and then perform the appropriate manipulation
of VTK objects in response to those?
I'm very interested in if you use some event forwarding code similar to
that in QVTKRenderWindowInteractor, or if you are simply not bothering with
feeding input events from Qt to VTK, and handling all input on the Qt side
of the fence so to speak.
