private var _width:int;
private var _text:TextField;
private var _loader:Loader;
private var _progressbar:Sprite
public function LoaderFriut()
{
trace(123132);
this.graphics.beginFill(0x000000);
this.graphics.drawRect(100,200,300,22);
this.graphics.endFill();
var f:TextFormat=new TextFormat();
f.color=0xFF0000;
f.font="华文彩云";
f.bold=true;
f.blockIndent=5;
f.size=15;
_text=new TextField()
_text.type=TextFieldType.DYNAMIC;
_text.setTextFormat(f);
_text.x=403;
_text.y=201;
_text.textColor=0xFF0000;
_loader=new Loader();
_loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS,drawProgess);
_loader.contentLoaderInfo.addEventListener(Event.COMPLETE,loaderOver)
_loader.load(new URLRequest("Friut.swf"));

}

private function drawProgess(evt:ProgressEvent):void{
this._progressbar = new Sprite();
this._progressbar.graphics.beginFill(0xFF0000);
var width:int=Math.round((evt.bytesLoaded/evt.bytesTotal)*300);
trace(width);
trace("你好 我现在 好像 可以监听进度"+evt.bytesLoaded+" "+evt.bytesTotal);
this._progressbar.graphics.drawRect(100,201,width,20);
this.addChild(this._progressbar);
this._text.text=evt.bytesLoaded*100/evt.bytesTotal+"%";
this.addChild(_text);
}

private function loaderOver(evt:Event):void{
this.loaderInfo.removeEventListener(ProgressEvent.PROGRESS,drawProgess);
this.loaderInfo.removeEventListener(Event.COMPLETE,loaderOver);
this.addChild(_loader);

}
}
}
我的代码执行后 没有播放Friut flash文件
