鼠标经过延时出现Hint

舞台上有个影片剪辑mc

库中有个元件hint由bg元件和文本txt组成

import flash.events.MouseEvent;



var time:int = 500;

var dyid:int;

var flag:Boolean;



mc.addEventListener(MouseEvent.ROLL_OVER,_onRollOver);

mc.addEventListener(MouseEvent.ROLL_OUT,_onRollOut);



function _onRollOver(e:MouseEvent):void

{

	dyid = setTimeout(delayed,time,e);

}

function delayed(e:MouseEvent):void

{

	flag = true;

	Hint.addHint(e,"延时"+time+"毫秒");

}

function _onRollOut(e:MouseEvent):void

{

	if (flag)

	{

		flag = false;

		Hint.removeHint();

	}

	clearTimeout(dyid);

}
