Enclosing class:

CStateMachine

public abstract class CStateMachine.EventOnShape
extends EventOnPosition

A transition triggered on a CShape in the canvas. OnShape transitions allow developpers to retrieve the shape in the canvas where this transition has been fired:

        Transition tshape = new EventOnShape ("anEvent") {
                public void action() {
                        // colors in red the shape on which the transition has been fired
                        getShape().setFillPaint(Color.RED);
                }
        }
