Class mxConnectionHandler

  • All Implemented Interfaces:
    java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.util.EventListener
    public class mxConnectionHandler
extends mxMouseAdapter
    Connection handler creates new connections between cells. This control is used to display the connector icon, while the preview is used to draw the line. mxEvent.CONNECT fires between begin- and endUpdate in mouseReleased. The cell property contains the inserted edge, the event and target properties contain the respective arguments that were passed to mouseReleased.
