大师帮助怎么在flex程序中现实插入一个延长时间呢?

Java code

            import mx.controls.Label;            import mx.containers.VBox;            import mx.managers.PopUpManager;            private var vbopenoff:Boolean=false;            private var vboxrs:VBox=new VBox();            private function openvbox():void            {             vbopenoff=true;             if(vbopenoff){                 vboxrs.removeAllChildren();             var textrs:Label=new Label();             textrs.text="gaowena";                          vboxrs.addChild(textrs);             PopUpManager.addPopUp(vboxrs,this,false);              movtophed(vboxrs,200,1500);                  }            }                           //如下是我的问题处            private function corso():void            {             if(vbopenoff){                      movtophed(vboxrs,-200,1500);//问题：我点corso是关上前面打开的vboxrs，这里看不到movtophed执行效果，请问在这里怎么现movtophed完整执行后再执行PopUpManager.removePopUp             PopUpManager.removePopUp(vboxrs);             }            }    import mx.effects.Move;    import mx.effects.easing.*; //移动特效上要用到的    //往上移动效果    private var moverss:Move;    private function movtophed(boxid:Object,yby:int,duration:int):void    {     moverss=new Move();     moverss.end();     moverss.target=boxid;     moverss.yBy=yby;     moverss.duration=duration;     moverss.play();    }-------------------------<mx:LinkButton label="open" click="openvbox()"/><mx:LinkButton label="coros" click="corso()"/>
