public abstract class ConnectionHandle extends SquareHandle implements java.beans.PropertyChangeListener
The base implementation for handles used with editparts whose figure is aConnection. 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.
