如何从另一个类触发ActionScript 3.0中的自定义事件

package {
    import flash.events.Event;
    
    public class CustomEvent extends Event {
        public static const CUSTOM_EVENT:String = "customEvent";
        public var customData:Object;
        
        public function CustomEvent(data:Object) {
            super(CUSTOM_EVENT);
            this.customData = data;
        }
        
        override public function clone():Event {
            return new CustomEvent(customData);
        }
    }
}

package {
    import flash.events.EventDispatcher;
    
    public class MyClass extends EventDispatcher {
        public function triggerCustomEvent(data:Object):void {
            var event:CustomEvent = new CustomEvent(data);
            dispatchEvent(event);
        }
    }
}

package {
    import flash.events.Event;
    
    public class AnotherClass {
        public function AnotherClass() {
            var myClass:MyClass = new MyClass();
            myClass.addEventListener(CustomEvent.CUSTOM_EVENT, handleCustomEvent);
        }
        
        private function handleCustomEvent(event:CustomEvent):void {
            var data:Object = event.customData;
            // 处理自定义事件数据
        }
    }
}
