-/**
- * An extension of java.awt.Event, specifically designed for
- * ImageButton events.<p>
- *
- * ImageButtonEvents are constructed with 3 arguments:
- * <dl>
- * <dd> ImageButton in which the event occurred
- * <dd> The AWT event that triggered the image button event
- * <dd> The id of the event.
- * </dl>
- *
- * An ImageButtonEvent's id (the constructor's 3rd argument),
- * must be one of the following:
- *
- * <dl>
- * <dd> ImageButtonEvent.ARM
- * <dd> ImageButtonEvent.DISARM
- * <dd> ImageButtonEvent.ACTIVATE
- * </dl>
- *
- * ImageButtonEvent has only a constructor and a paramString()
- * method. Containers that contain ImageButtons should check
- * for ImageButtonEvents like so: <p>
- *
- * <pre>
- * // handleEvent(Event) method of a container that
- * // contains ImageButtons.
- *
- * public boolean handleEvent(Event event) {
- * if(event instanceof ImageButtonEvent) {
- * ImageButtonEvent ibevent =
- * (ImageButtonEvent)event;
- *
- * if(ibevent.isArmed()) {
- * // do something for arming
- * }
- * if(ibevent.isDisarmed()) {
- * // do something for disarming
- * }
- * if(ibevent.isActivated()) {
- * // do something for activation
- * }
- * }
- * }
- * </pre>
- *
- * ImageButtonController is the only GJT class that creates
- * ImageButtonEvents.
