Kenny -
Your component needs to be an EventDispatcher... if it is extending an
existing DisplayObjects, then it already is. If not, you can just
extend EventDispatcher yourself. Then your component can notify parents
etc. by creating an event of the appropriate type and dispatching. For
instance here is an event you could dispatch on change:
//create a change event and notify...
var evt:Event = new Event(Event.CHANGE, true, false);
this.dispatchEvent(evt);
Note: You may or may not want the event to bubble... that will depend on
whether or not the listener is attached directly to your component (or
one of its ancestors).
If you want to send data out with the click you can create a new custom
event (extend Event) and add your data property... then instantiate your
custom event type and dispatch one of those instead. Example:
public class MyEvent extends Event
{
public static const TYPE:String = "myEvent";
public var eventData:Object = null;
public function MyEvent(data:Object, bubbles:Boolean = false,
cancellable:Boolean = false)
{
super(MyEvent.TYPE, bubbles, cancellable);
this.eventData = data;
}
}
and in your click handler:
var evt:MyEvent = new MyEvent(myData, true);
this.dispatchEvent(evt);
The code that listens for this custom event can just do something like:
//attach to the component and listen for a MyEvent type event
myComponent.addEventListener(MyEvent.TYPE, handleMyEvent, false, 0, true);
public function handleMyEvent(event:MyEvent):void
{
//handle the event...
}
