virtual void Enable()
Enable/Disable interactions.
virtual char * GetKeySym()
Set/get the key symbol for the key that was pressed.
virtual int InternalDestroyTimer(int platformTimerId)
Internal methods for creating and destroying timers that must be implemented by subclasses.
implements Win32 specific functions required by vtkRenderWindowInteractor.
