org.eclipse.gef.handles
Class ConnectionHandle

java.lang.Object
  extended by

org.eclipse.draw2d.Figure
      extended by

org.eclipse.gef.handles.AbstractHandle
          extended by

org.eclipse.gef.handles.SquareHandle
              extended by
org.eclipse.gef.handles.ConnectionHandle
All Implemented Interfaces:
AncestorListener, java.util.EventListener, Handle, IFigure, java.beans.PropertyChangeListener
Direct Known Subclasses:
BendpointHandle, ConnectionEndpointHandle

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.
