Event triggering from a class to parent

Question

Hi,
             I am trying to write a custom class for image loading.
public function imageLoader(url:String, mc:MovieClip):void {
                              loader = new Loader();
                              loader.load(new URLRequest(url));
                              mc.addChild(loader);
                              loader.contentLoaderInfo.addEventListener(Event.INIT, initListener);
                              loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, progressListener);
                              loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadListener);
                    public function initListener(e:Event):void {
                    public function progressListener(e:ProgressEvent):void {
                    public function loadListener(e:Event):void {
I ll get the events in these listeners in the loadImage class. But i want to trigger a function in the calling class or root or stage, when these loader events are fired.
How this can be done?

Answer 1

the ImageLoader class should extend EventDispatcher
you cna then redispatch the events wihtin the ImageLoader class
e.g.
public function initListener(e:Event):void {
     dispatchEvent(e);
then in the parent class you will have a reference to the ImageLoader class and you can add event listeners there
e.g.
var imageLoader:ImageLoader = new ImageLoader();
imageLoader.addEventListener(Event.INIT, somefunction);
imageLoader.load("image", this);
or something alone these lines depending on how you want to structure things
