AS3 dispatchEvent 在课堂上不起作用

Question

我创建了这个事件类：

package com.site {
    import flash.events.Event;

    public class clientEvent extends Event {
        public static const connectionSucceeded: String = "connectionSucceeded";

        public var prams: Object;

        public function clientEvent(type: String, prams: Object) {
            super(type);
            this.prams = prams;
        }
        override public function clone(): Event {
            return new clientEvent(type, prams);
        }
    }
}

在我写的其他类（非主类）上：

dispatchEvent(new clientEvent(clientEvent.connectionSucceeded, new Object()));

我导入该类并返回此错误： 1180: 调用一个可能未定义的方法 dispatchEvent。

Answer 1

另一个类应该扩展EventDispatcher类。
