Question

如何命令预加载器跟踪下载进度？

 public function loadImage(filename:String):void
        {
            // show the preloader
            preloader.visible = true;

    // set the source to the UILoader to the full size image to load and display

            addChild(preloader);

            // 
            var loadWindow:UILoader;    
        preloader.trackLoading("LOADING: " + (loader*100).toFixed(0) + "%");


        }
