AS3:老鼠离开舞台时不开火

我正在开发一个包含导航项的网站,从上到下覆盖整个舞台(见下面的修改图片),用户很容易用鼠标退出舞台,而不是触发 MouseEvent.MOUSE_OUT 需要“关闭”所述导航项的事件。

我应该用吗 Event.MOUSE_LEAVE 要检测鼠标何时离开舞台,并关闭任何已启用的导航项?这就是我一直想做的,但从我的听众那里得到任何输出都有困难。有什么想法吗?

对于在flash-ide中与movieclip关联的类,这是注册 event.mouse离开 倾听者?不管我做什么,它似乎都不起作用。在这种情况下,我必须将电影嵌入浏览器才能触发事件吗?

this.stage.addEventListener(Event.MOUSE_LEAVE, mouseLeaveListener);

这是我的主导航系统。

package com.redpropeller {

import com.greensock.*;
import com.greensock.plugins.*;
import flash.display.*;
import flash.text.*;
import flash.events.*;

public class MainNav extends MovieClip { // MainNav is a movieclip in the IDE

    public var colors:Array;

    public function MainNav():void {
        colors = new Array(0xee3124, 0xc72a1f, 0xa62c24, 0x912923, 0x7e221c);
        TweenPlugin.activate([TintPlugin]);

        // trying to target stage through this object
        this.stage.addEventListener(Event.MOUSE_LEAVE, mouseLeaveListener);

        for(var i:Number=0; i<this.numChildren; i++){
            var n = this.getChildAt(i);
            n.useHandCursor = true;
            n.buttonMode = true;

            n.addEventListener(MouseEvent.MOUSE_OVER, navBtnOn);
            n.addEventListener(MouseEvent.MOUSE_OUT, navBtnOff);
        }
    }
    public function mouseLeaveListener(e:Event):void {
        trace('mouseleave'); // nothing ever happens

    }
    private function navBtnOn(e:MouseEvent):void {
        TweenLite.to(e.currentTarget.bar_mc, 0.01, {tint:0x333333});
    }
    private function navBtnOff(e:MouseEvent):void {
        TweenLite.to(e.currentTarget.bar_mc, 0.01,
            {tint:uint(colors[this.getChildIndex(MovieClip(e.currentTarget))])});
            // changes color back to specific tint
    }
}

}
