[vtkusers] Qt and keyboard events

[Shakes]

Hi Jon,

VTK uses observers to look out for events. Use the RemoveObservers() 
members of the interactor to unbind the ones u want. You can find the 
list of events in vtkCommand class docs. For example:

///Unbind the right mouse button events as Qt uses context menu.
QVTKWidget::GetRenderWindow()->GetInteractor()->RemoveObservers(vtkCommand::RightButtonPressEvent);
QVTKWidget::GetRenderWindow()->GetInteractor()->RemoveObservers(vtkCommand::RightButtonReleaseEvent);

As for getting Qt and VTK to do things simultaneously, u could use the 
vtkCallbackCommand or vtkEventForwarderCommand to redirect the events 
and call Qt stuff. I haven't done this, so perhaps someone else knows a 
better way.

Hope that helps
Cheers
Shakes
