All Implemented Interfaces:
-
AncestorListener, java.util.EventListener,
Handle,
IFigure, java.beans.PropertyChangeListener

- public abstract class ConnectionHandle
- extends
SquareHandle
- implements java.beans.PropertyChangeListener
The base implementation for handles used with editparts whose figure is a
Connection . This class adds an additional listener to the owner's
connection figure to receive notification whenever the owner's connection's points are
changed. Changing the points of a connection does not fire "figure moved", it only
fires "points" property as changing.
