[vtkusers] QT and vtkMouse interaction

[Alex Malyushytskyy]

Override interactor style most suitable for you and set it to
QVTKWidget  interactor

If you need to get pointer to interactor,
use QVTKWidget GetRenderWindow()->GetInteractor():

	this->GetRenderWindow()->GetInteractor()->SetInteractorStyle(
m_ViewModelInteractorStyle );


You may find vtkEventQtSlotConnect useful if you want qt slot be
called as a result of vtk event

	vtkSmartPointer<vtkEventQtSlotConnect> Connections;
....

	Connections = vtkSmartPointer<vtkEventQtSlotConnect>::New();
	// connect window enter event to radio button slot

	Connections->Connect( this->GetRenderWindow()->GetInteractor(),
             vtkCommand::EndPickEvent, this, SLOT(  onEndPickEvent() ));
	Connections->Connect( this->GetRenderWindow()->GetInteractor(),
             vtkCommand::StartPickEvent, this, SLOT(  onStartPickEvent() ));

	Connections->Connect(
this->GetRenderWindow()->GetInteractor()->GetInteractorStyle(),
             InteractionModeSetStartEvent, this, SLOT(
onInteractionModeChangedByInteractor() ));
	Connections->Connect(
this->GetRenderWindow()->GetInteractor()->GetInteractorStyle(),
             BoxZoomEndEvent, this, SLOT(  onEndZoomEvent() ));

Or you can use callbacks if you prefer non C++ mechanics as usually.
