GrafEdit - ContinueInteration

ContinueInteration

The MouseMoved event calls ContinueInteraction only when you are not in the process of drawing a selection rectangle. This happens when you click and drag a graphic in one operation. Again, this is similar to the TCanvasGraphicTranslatingInteractor.

  void        
  TCanvasSelectionInteractor::ContinueInteraction ()
  {
      unsigned long n = GetNumberOfPoints ();
      if ( n >= 2 ) {
          fCommand->SetOffset (GetPoint(n-1)-GetPoint(n-2));
          DoIncrement (*(fBinding.GetObject()));
          }
  }
