QVTKInteractorAdapter::ProcessEvent shall reject the event if not swallowed
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When typing Enter or Escape in QVTKWidget or QVTKWidget2, the key might not be used by the interactor style. Therefore QVTKWidget[2]::keyPressEvent must propagate the event to its parent (or at least call reject on the event object) as defined in the API documentation of QWidget::keyPressEvent: """If you reimplement this handler, it is very important that you call the base class implementation if you do not act upon the key."""
