stage.addEventListener包里面？ [英] stage.addEventListener inside a package?

问题描述

我试图做这样的事情：

package com.clicker{
    import flash.display.*;
    import flash.events.MouseEvent;

    public class Stager extends MovieClip {

        public function clicker():void {
            stage.addEventListener(MouseEvent.CLICK, do_stage);
        }
        function do_stage(e:MouseEvent):void {
            trace("stage clicked");
        }

    }
}

不过，我得到了1009的错误。

But, I get the 1009 error.

当我这样做：

import com.clicker.*;

var test:Stager = new Stager();
test.clicker();
addChild(test); 

请帮助我。非常感谢你提前和节日快乐。

Please help me. Thank you very much in advance, and Happy Holidays.

推荐答案

阶段访问只有当你的组件添加到舞台上。如果你想知道的话，你可以使用ADDED_TO_STAGE事件。

stage is accessible only when your component is added to the stage. If you want to know it, you can use the ADDED_TO_STAGE event.

所以，你可以这样做：

package com.clicker{
    import flash.display.*;
    import flash.events.*;

    public class Stager extends MovieClip {

        public function clicker():void {
            addEventListener(Event.ADDED_TO_STAGE, init);
        }
        private function init(e:Event):void {
            removeEventListener(Event.ADDED_TO_STAGE, init);
            stage.addEventListener(MouseEvent.CLICK, do_stage);
        }
        function do_stage(e:MouseEvent):void {
            trace("stage clicked");
        }

    }
}
