public interface GraphicBagHierarchyEventReceiver

Objects that can receive graphic bag hierarchy events should implement this interface. Currently, IlvManager, IlvGraphicSet and IlvGraphicHandleBag can send and receive hierarchy events, hence they implement this interface.

Since:

JViews 8.1

Method Summary

Modifier and Type	Method and Description
void	addGraphicBagHierarchyListener(GraphicBagHierarchyListener listener) Adds the specified listener to receive events from ancestors and from this object when the hierarchy of graphic bags has changed.
void	enableGraphicBagHierarchyEventForwarding() Enables forwarding of GraphicBagHierarchyEvent events, since the subobjects contained in this object need to receive the events.
void	fireGraphicBagHierarchyEvent(GraphicBagHierarchyEvent event) Fires a graphic bag hierarchy event to this object and all contained objects.
boolean	needsGraphicBagHierarchyEvent() Returns whether the object needs to receive GraphicBagHierarchyEvent events, either from itself or from its ancestors.
void	removeGraphicBagHierarchyListener(GraphicBagHierarchyListener listener) Removes the specified listener so that it no longer receives events from ancestors and from this object when the hierarchy of graphic bags has changed.

Method Detail

addGraphicBagHierarchyListener

void addGraphicBagHierarchyListener(GraphicBagHierarchyListener listener)

Adds the specified listener to receive events from ancestors and from this object when the hierarchy of graphic bags has changed. The hierarchy event is generated by an object (a manager or graphic set) when it is added to or removed from another graphic bag, and passed down the hierarchy. The event is dispatched to every receiver that is contained in the object whose graphic bag has changed.

Parameters:

listener - The listener.

removeGraphicBagHierarchyListener

void removeGraphicBagHierarchyListener(GraphicBagHierarchyListener listener)

Removes the specified listener so that it no longer receives events from ancestors and from this object when the hierarchy of graphic bags has changed.

Parameters:

listener - The listener.

addGraphicBagHierarchyListener(ilog.views.event.GraphicBagHierarchyListener)

enableGraphicBagHierarchyEventForwarding

void enableGraphicBagHierarchyEventForwarding()

Enables forwarding of GraphicBagHierarchyEvent events, since the subobjects contained in this object need to receive the events.

needsGraphicBagHierarchyEvent

boolean needsGraphicBagHierarchyEvent()

Returns whether the object needs to receive GraphicBagHierarchyEvent events, either from itself or from its ancestors.

fireGraphicBagHierarchyEvent

void fireGraphicBagHierarchyEvent(GraphicBagHierarchyEvent event)

Fires a graphic bag hierarchy event to this object and all contained objects.
