Question

我有一个flex的对象 - 我希望在点击一个按钮时出现，10秒后消失或对象关闭，如果按下相同的按钮则重新出现。

我尝试过这样的事情：

public class my_obj
{
  private var _myTimer: Timer;

     public function my_obj()
     {
           _myTimer = new Timer(10000);

     }
     private function init(): void
     {
           _myTimer.addEventListener(TimerEvent.TIMER, onTimeout);
            _myTimer.start();
     }

     private function onTimerTimeOut(event: TimerEvent): void
     {
        dispatchEvent(new Event(CLOSE_EVENT));
     }
}

我错过了什么？谢谢！
