    • notifyPainting

      public void notifyPainting(Rectangle damage, Map<IFigure,Rectangle> dirtyRegions)
      Description copied from interface: UpdateListener
      Notifies the listener that the listened to object is painting. The damage rectangle may be null or empty. This indicates the dirty regions were clipped or not visible. But for objects such as the Thumbnail, notification still needs to occur. The map of dirty regions is passed to allow the listener to determine if it needs to update, for instance when a particular figure is painting.
      Specified by:
      notifyPainting in interface UpdateListener
      Parameters:
      damage - The area being painted
      dirtyRegions - a Map of figures to their dirty regions
