在Flash CS4中使用加载程序组件时出现问题。

var req : URLRequest = new URLRequest(\"Gallery.swf\");
var loader : Loader = new Loader( );
loader.load(req);
addChild(loader);

loader.scaleX = 0.5;
loader.scaleY = 0.5;
loader.x = 100;
loader.y = 100;

var req : URLRequest = new URLRequest(\"Test2.swf\");
var loader : Loader = new Loader( );
loader.contentLoaderInfo.addEventListener(Event.COMPLETE , swfLoaded);
loader.load(req);

function swfLoaded( ev: Event ):void
{
  addChild(loader); 
}

function swfLoaded( ev: Event ):void
{
  var swf : MovieClip = MovieClip(loader.content);
  swf.play();   
}
