Class CStateMachine.EventOnTag

java.lang.Object
  fr.lri.swingstates.sm.Transition
      fr.lri.swingstates.sm.transitions.Event

Direct Known Subclasses:: CStateMachine.MouseOnTag

Enclosing class:: CStateMachine

public abstract class CStateMachine.EventOnTag
extends CStateMachine.EventOnShape
extends CStateMachine.EventOnShape

A transition triggered on a tagged shape. OnTag transitions allow developpers to retrieve the shape and the tag where this transition has been fired:

  class ColorTag extends CNamedTag {
                Color color;
                public ColorTag(String tagName, Color c) {
                        super(n);
                }
  }
  ...
  CShape ellipse1 = canvas.newEllipse(100, 100, 20, 30);
  CShape ellipse2 = canvas.newEllipse(200, 200, 20, 30);
  CShape rectangle = canvas.newRectangle(300, 300, 20, 30);
  ColorTag red = new ColorTag("red", Color.RED);
  red.addTo(ellipse1).addTo(rectangle);
  ColorTag green = new ColorTag("green", Color.GREEN);
  green.addTo(ellipse2);

Transitions can be marked by a tag:

  // The transition is triggered when an event occurs on ellipse1 or on rectangle.
        Transition t = new EventOnTag (red, BUTTON1) {
                public void action() {
                        ...
                        // scale ellipse1 and rectangle
                        getTag().scaleBy(1.5);
                        // set the transparencyFill of the shape on which this transition has been triggered (ellipse1 OR rectangle)
                        getShape().setTransparency(0.5f);
                }
        }

Transitions can be marked by a class of tag:

  // The transition is triggered when an event occurs on ellipse1, ellipse2 or on rectangle (any shape tagged by an instance of ColorTag).
        Transition t = new EventOnTag (ColorTag.class, BUTTON1) {
                public void action() {
                        ...
                        getShape().setFillPaint(((ColorTag)getTag()).color));
                        ...
                }
        }

Transitions can be marked by the name of the tag (if the tag is an instance of a subclass of a CNamedTag):

  // The transition is triggered when an event occurs on ellipse2 (the only shape tagged by the instance of ColorTag having the name "green").
        Transition t = new EventOnTag ("green", BUTTON1) {
                public void action() {
                        ...
                        System.out.println("This shape is tagged by the color "+((ColorTag)getTag()).color);
                        ...
                }
        }

Method Summary
`CTag`	`getTag()` Returns the tag instance hold by the CShape on which the mouse event firing this transition has occurred.
