Class GraphicBagHierarchyEvent

java.lang.Object
  java.util.EventObject
      ilog.views.event.GraphicBagHierarchyEvent

All Implemented Interfaces:

Serializable

public class GraphicBagHierarchyEvent
extends EventObject

An GraphicBagHierarchyEvent event is fired when the hierarchy of graphic bags changed. This event is generated by a graphic bag (manager or graphic set) when the graphic bag is added to or removed from another graphic bag, and passed down the hierarchy. The event is dispatched to every IlvManager IlvGraphicBag and IlvGraphicHandleBag that is contained in the graphic bag whose own bag has changed.

Note: not all graphic bags support GraphicBagHierarchyEvent. Graphic bags that cannot be contained in other graphic bags don't need to support this event. Only IlvManager, IlvGraphicBag and IlvGraphicHandleBag support this event, i.e. they are able to fire the event and also able to receive the event.
