Creating Class for preloader.How?

programming flash

Hi!

I am new to Actionscript 3.0 and to create classes but I am trying to create a class to preload every swfFile I have on my site.How would I do this?

I was trying this:


Package
{
    public class Carregador
    {
        public function loadSwf(swfFile:String):void 
        {
            var request:URLRequest = new URLRequest(swfFile);
            var loader:Loader = new Loader();
            
            loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loadProgress);
            loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
            loader.load(request);
            addChild(loader);
        }
        
        public function loadProgress(event:ProgressEvent):void {
            var percentLoaded:Number = event.bytesLoaded/event.bytesTotal;
            percentLoaded = Math.round(percentLoaded * 100);
            trace("Loading: "+percentLoaded+"%");
        }
        
        function loadComplete(event:Event):void {
            trace("Complete");
        }
    }
}

How would I show a progress bar(MC) that is on my stage?Would I have to send the name of a bar so that my class could increment its _x property?How does It work?

And how would I load my swf file into an empty MC like usual?
