让mc元件随浏览器尺寸改变位置

//固定的mc
private function gudingmc() {
     comanylogo.x = stage.stageWidth -comanylogo.width;
     stage.align = "TL";
     stage.addEventListener(Event.RESIZE,stageResize);
}
private function stageResize(e:Event):void{
    //comanylogo.y =stage.stageHeight-comanylogo.height;
     comanylogo.x =stage.stageWidth-comanylogo.width;
}

　　显示在浏览器中的mc,不管浏览器大小如何改变，mc始终浮动在固定的位置。
