com.tensegrity.graph.event
Class VisualGraphEvent

java.lang.Object
  com.tensegrity.graph.event.AbstractVisualGraphEvent
      com.tensegrity.graph.event.VisualGraphEvent

All Implemented Interfaces:: VisualGraphRootEvent

public class VisualGraphEvent
extends com.tensegrity.graph.event.AbstractVisualGraphEvent

A visualgraph event. This class encapsulates event information for both VisualGraphViews and for VisualSubgraphs. It is possible to add a VisualGraphListener or a VisualGraphEventMediator to the two previously mentioned types, which in turn will be invoked when events occur. The information that is associated with a single event is packaged into an instance of this class.

If an instance of this class was triggered by an action inside of a VisualGraphView then a reference to the actual instance can be obtained by invoked the method AbstractVisualGraphEvent.getVisualGraph()

If an instance of this class was triggered by an action inside of a VisualSubgraph then a reference to the actual instance can be obtained by invoked the method AbstractVisualGraphEvent.getVisualSubgraph()

Since the source of the event can be only either one of the two types, one of the two methods will return null and the other one will return the event source.
