Class mxRotationHandler

java.lang.Object

com.mxgraph.swing.util.mxMouseAdapter

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!
