自定义组件中的事件问题
我刚刚开始使用自定义组件中的自定义事件。我还不太掌握它的窍门。
我有一个带有按钮的组件。单击时，我想调用主应用程序中的函数。
自定义组件：
<mx:Panel xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute" >
<mx:Metadata>
[Event(name="goClick", type="mx.events.Event")]
</mx:Metadata>
<mx:Script>
<![CDATA[
private function onButtonClickHandler(event:MouseEvent):void {
dispatchEvent(new Event("goClick"));
}
]]>
</mx:Script>
<mx:Button id="myGoButton" label="Go"
click="onButtonClickHandler(MouseEvent)" />
</mx:Panel>
主应用程序：
<myFolder:MyComponent
goClick="MyCoolFunction()">
不幸的是，我做错了。它说事件类型不可用。我需要更改或添加什么？我的猜测是我需要以某种方式声明 goClick？
谢谢你！

I'm just getting started with custom events in a custom component. And I don't quite have the hang of it, yet.
I've got a component with a button in it. When it's clicked, I want to call a function in the main app.
Custom Component:
<mx:Panel xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute" >
<mx:Metadata>
[Event(name="goClick", type="mx.events.Event")]
</mx:Metadata>
<mx:Script>
<![CDATA[
private function onButtonClickHandler(event:MouseEvent):void {
dispatchEvent(new Event("goClick"));
}
]]>
</mx:Script>
<mx:Button id="myGoButton" label="Go"
click="onButtonClickHandler(MouseEvent)" />
</mx:Panel>
Main App:
<myFolder:MyComponent
goClick="MyCoolFunction()">
Unfortunately, I'm doing something wrong. It says that the Event type is unavailable. What do I need to change or add? My guess is that I need to declare goClick in some way?
Thank you!

除非您创建了 mx.events.Event 这样的类，否则没有此类。将其更改为 flash.events.Event 就可以了。
如果您确实创建了“mx.events.Event”类，请确保您的调度事件是创建自定义类的实例，而不是 flash.events.Event。
No such class as mx.events.Event unless you created one. Change that to flash.events.Event and you'll be good to go.
If you did create an 'mx.events.Event" class, make sure that your dispatch event is create an instance of your custom class and not the flash.events.Event.
