Qt is already capturing the events, but it delgates the processing of those events to vtkRenderWindowInteractor, which in turn works with vtkInteractorObservers.

If you want to customize event processing, it is recommended that you make a vtkInteractorStyle class to do that, so that any other vtkInteractorObservers you decide to use will also work.

Otherwise, if you really want to, just overload the normal QWidget functions for capturing events and process them yourself.  Its just like any other QWidget.
