Class ConnectionStartHandle

java.lang.Object
  org.jhotdraw.draw.AbstractHandle
      org.jhotdraw.draw.AbstractConnectionHandle
          org.jhotdraw.draw.ConnectionStartHandle

All Implemented Interfaces:

public class ConnectionStartHandle
extends AbstractConnectionHandle

Handle to reconnect the start of a connection to another figure.

Version:

3.0 2007-05-18 Changed due to changes in the canConnect methods of the ConnectionFigure interface. Shortened the name from ChangeConnectionStartHandle to ConnectionStartHandle.
2006-01-14 Changed to support double precision coordinates.
1.0 2003-12-01 Derived from JHotDraw 5.4b1.
