An event is just a message object. Just because one gets created
successfully does not mean it is being delivered. dispatchEvent() is a
method of the EventDispatcher class, which is a superclass of many classes,
including DisplayObject. You need to listen for the event (with
addEventListener()) on the same EventDispatcher where the event was
dispatched. (Except in the case of events that bubble, but that's another
topic.)
For example:
public class MyWindowHolder extends Sprite {
public function init(): void {
var a: MyWindow = new MyWindow();
a.addEventListener( MyEvent.EXCLAMATION, onExclamation );
}
private function onExclamation( event: MyEvent ): void {
trace("ouch!");
}
}
public class MyWindow extends Sprite {
private function injury(): void {
this.dispatchEvent( new MyEvent( MyEvent.EXCLAMATION ));
}
}
Hope this helps,
Dave
