示例1: DynamicMouseMove

void AnnotationInterface::DynamicMouseMove( View& v, const DPoint& p, unsigned buttons, unsigned modifiers )
{
   // mouse move is processed only on active view
   if (view == 0 || v != *view)
      return;

   // get view image window
   ImageWindow w = view->Window();

   // and image coordinates of the mouse position
   int imageX = RoundI(p.x);
   int imageY = RoundI(p.y);

   // set cursor to dragging cursor if mouse is inside one of the grip rectangles
   if (annotationPlaced && textRect.Includes(imageX, imageY))
      w.SetDynamicCursor(move_all_XPM, 10, 10);
   else if (leaderPlaced && instance.annotationShowLeader && leaderRect.Includes(imageX, imageY))
      w.SetDynamicCursor(move_all_XPM, 10, 10);
   else // otherwise, reset cursor
      w.ResetDynamicCursor();

   // if we are currently dragging something
   if ( dragging != DraggingType::None )
   {
      // compute delta
      int deltaX = imageX-lastX;
      int deltaY = imageY-lastY;

      // update text position if needed
      if (dragging == DraggingType::Text || dragging == DraggingType::Both)
      {
         instance.annotationPositionX += deltaX;
         instance.annotationPositionY += deltaY;
      }

      // update leader endpoint position if needed
      if (dragging == DraggingType::Leader || dragging == DraggingType::Both)
      {
         instance.annotationLeaderPositionX += deltaX;
         instance.annotationLeaderPositionY += deltaY;
      }

      // update annotation rectangle
      UpdateAnnotationRect();

      // redraw dynamic view
      UpdateView();

      // remember current point
      lastX = imageX;

   }

   // only handle events in our active view
   if (v != *view)
      return;

   // get view image window
   ImageWindow w = view->Window();

   // and image coordinates of the click point
   int imageX = RoundI(p.x);
   int imageY = RoundI(p.y);

   // if annotation is not yet placed, place it now
   if (!annotationPlaced)

      if (instance.annotationShowLeader)
      {

      }

      // update annotation rectangle
      UpdateAnnotationRect( true );

      // redraw dynamic view
      UpdateView();

      // start dragging mode until user release the mouse
      dragging = DraggingType::Text;
      w.SetDynamicCursor(move_all_XPM, 10, 10);
   }
   // if the annotation is already placed
   else
   {
