MouseMoved

The MouseMoved event draws the selection feedback (through the inherited DrawFeedback function) or continues moving a graphic that had been clicked on. 

      bool
  TCanvasSelectionInteractor::MouseMoved (TMouseMovedEvent& theEvent)
  {
      TGPoint p = theEvent.GetEventPosition ();
      
      if ( p != GetLastPoint() ) {
          RecordPoint (p);
          if ( fRectSelecting ) DrawFeedback ();
          else
              ContinueInteraction ();
          }
          
      return true;
  }
