mxGraph 1.10.4.0


com.mxgraph.swing.handler
Class mxRotationHandler

java.lang.Object
  extended by com.mxgraph.swing.util.mxMouseAdapter
      extended by com.mxgraph.swing.handler.mxRotationHandler
All Implemented Interfaces:
MouseListener, MouseMotionListener, EventListener

public class mxRotationHandler
extends mxMouseAdapter

Basic example of implementing a handler for rotation. This can be used as follows: new mxRotationHandler(graphComponent) Note that the Java core does actually not support rotation for the selection handles, perimeter points etc. Feel free to contribute a fix!
