我的闪光自定义事件不会触发 [英] My flash custom event doesn't trigger

问题描述

还有就是我的自定义事件的无痕输出，为什么？

与价值属性自定义事件类：

 包{

    进口对象类型：flash.events.Event;

     公共类自定义事件扩展事件
     {
        公共静态常量ON_CUSTOM_EVENT：字符串=onCustomEvent;
        公共VAR值：数字;

        公共功能自定义事件（类型：字符串，气泡：布尔=假，取消：布尔=假）：无效
        {
           超（类型，泡沫，取消）;
        }

     }

}
 

测试采用了滑盖刚刚重新调度滑块事件类：

 包{

    导入flash.display使用*。
    进口flash.net *。
    进口flash.events *。
    进口fl.events.SliderEvent;
    进口fl.controls.Slider;

    公共类TestCustomEvent扩展影片剪辑{

      私人VAR CEvent的：自定义事件;

      公共职能TestCustomEvent（）{

        的addEventListener（Event.ADDED_TO_STAGE，INIT）;

      }

      公共职能的init（五：事件）：无效{

        removeEventListener（Event.ADDED_TO_STAGE，INIT）;

        this.addEventListener（CustomEvent.ON_CUSTOM_EVENT，OnCustomEvent）;
        slider.addEventListener（SliderEvent.CHANGE，OnSliderEventChange）;

      }



      公共职能OnCustomEvent（事件：自定义事件）：无效{

            跟踪（event.value）;
      }


      公共职能OnSliderEventChange（事件：的SliderEvent）{

            CEvent的=新的自定义事件（OnCustomEvent）;
            cEvent.value = event.value;
            则dispatchEvent（CEvent的）;
                    跟踪（你好）;

      }

    }
}
 

解决方案

ON_CUSTOM_EVENT：字符串= onCustomEvent

与的

CEvent的=新的自定义事件（ OnCustomEvent ）;

（案例题）

您不应写入字符串第二次，但使用 CustomEvent.ON_CUSTOM_EVENT

There is no trace output of my custom event why ?

CustomEvent class with value property:

package {

    import flash.events.Event;

     public class CustomEvent extends Event
     {
        public static const ON_CUSTOM_EVENT:String = "onCustomEvent";
        public var value:Number;

        public function CustomEvent(type:String, bubbles:Boolean=false, cancelable:Boolean=false):void
        {
           super(type, bubbles, cancelable);
        }

     }

}

Test class with a slider which just re-dispatches the slider event:

package {

    import flash.display.*;
    import flash.net.*;
    import flash.events.*;
    import fl.events.SliderEvent;
    import fl.controls.Slider;

    public class TestCustomEvent extends MovieClip {        

      private var cEvent: CustomEvent;

      public function TestCustomEvent() {   

        addEventListener( Event.ADDED_TO_STAGE, init);  

      }

      public function init( e:Event ):void {

        removeEventListener( Event.ADDED_TO_STAGE, init );

        this.addEventListener(CustomEvent.ON_CUSTOM_EVENT,OnCustomEvent);
        slider.addEventListener(SliderEvent.CHANGE,OnSliderEventChange);

      } 



      public function OnCustomEvent(event:CustomEvent): void {

            trace(event.value);
      }


      public function OnSliderEventChange(event:SliderEvent) {

            cEvent = new CustomEvent("OnCustomEvent");
            cEvent.value = event.value;
            dispatchEvent(cEvent);
                    trace("hello");

      }

    }       
}

解决方案

ON_CUSTOM_EVENT:String = "onCustomEvent"

versus

cEvent = new CustomEvent("OnCustomEvent");

(case problem)

You shouldn't write the string the second time but use CustomEvent.ON_CUSTOM_EVENT
