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.-
