Hi, I am new to classes and object. I have just written a class file and I need an expert opinion about my class, so that I could learn more. I would like to know if we can make some improvement in the coding or whether the class is well encapsulated etc.


package {

    import flash.display.*;
    import flash.events.*;
    import flash.net.*;

    public class ShowCompletePic extends MovieClip {

        private var imageLoader:Loader = new Loader();
        private var loadPic_mc:MovieClip = new MovieClip();
        private var url:String;

        public function ShowCompletePic(path:String) {
            url=path;
            addChild(loadPic_mc);
            imageLoader.load(new URLRequest(url));
            loadPic_mc.addChild(imageLoader);

            imageLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, imageLoading);
            imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageLoaded);

        }
        private function imageLoaded(e:Event):void {
            loadPic_mc.addChild(imageLoader);
            loadPic_mc.x=(stage.stageWidth/2)-(loadPic_mc.width/2);
            loadPic_mc.y=(stage.stageHeight/2)-(loadPic_mc.height/2);
            stage.addEventListener(MouseEvent.MOUSE_MOVE,movePicture);
            function movePicture(event:MouseEvent):void {
                if (loadPic_mc.width>stage.stageWidth) {
                    loadPic_mc.x=-(loadPic_mc.width-stage.stageWidth)*parent.mouseX/stage.stageWidth;
                }
                if (loadPic_mc.height>stage.stageHeight) {
                    loadPic_mc.y=-(loadPic_mc.height-stage.stageHeight)*parent.mouseY/stage.stageHeight;
                }
            }
        }
        private function imageLoading(e:ProgressEvent):void {

            trace((e.bytesLoaded / e.bytesTotal) * 100);

        }
    }
}

Thanks in advance
