46 //! Introduction of the class is intended to implement Qt based #CreateTimer and #DestroyTimer functionality.
48 The class intendes to implement platform indepenedant subclass of vtkRenderWindowInteractor.
49 This is done by usage of Qt library.
51 The Signal/Slot mechanism used by Qt requires that QObject
52 appear as the first class when using multiple inheritance.
53 Hence the order of the two classes QObject and vtkRenderWindowInteractor
54 matters here. So, be careful, not to change the sequence of the inheritance by accident.
56 class SVTK_EXPORT QVTK_GenericRenderWindowInteractor:
58 public vtkGenericRenderWindowInteractor
63 static QVTK_GenericRenderWindowInteractor* New();
64 vtkTypeMacro(QVTK_GenericRenderWindowInteractor,vtkGenericRenderWindowInteractor);
66 //! Starts the QTimer instance on defined microseconds
71 //! Stops the QTimer instance
77 //! The slot connects to QTimer::timeout signal to invoke vtkCommand::TimerEvent
82 QVTK_GenericRenderWindowInteractor(); //!< Instatiate QTimer
83 ~QVTK_GenericRenderWindowInteractor(); //!< Destroy the instance of QTimer
85 QTimer* myTimer; //!< Qt timer device
89 //============================================================================
90 //! This class introduce SALOME specific to the base one
92 In this class new members is added (#mySelector and #myRenderWidget).
93 They are used for initialization of #SVTK_InteractorStyle by redefinition of
94 #SVTK_InteractorStyle::SetInteractor method
