关于flex中IMXMLObject的一点心得

??? 在flex中可以通过IMXMLObject的实现来达到对纯as3类的mxml显示支持；以前没怎么了解过 今天看了下 感觉用起来还是很方便；

其实非常简单 只需要把你自己的类实现IMXMLObject 接口就可以了 。

比如：

package com
{
	import flash.display.Sprite;
	import flash.events.Event;
	
	import mx.core.IMXMLObject;

	[Event(name="result",type="flash.events.Event")]
	/**
	 *
	 * @author txiejun

	 */
	public class Remote extends Sprite implements IMXMLObject
	{
		private var document:Object;
		private var id:String;
		public function Remote()
		{
			super();
		}
		
		public function initialized(document:Object,id:String):void
		{
			this.document = document;
			this.id = id;
			this.dispatchEvent(new Event("result"));
		}
	}
}

[Event(name="result",type="flash.events.Event")]

这样就可以在mxml标签中直接通过提示打出来你想要的result事件标识了；

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
			   xmlns:s="library://ns.adobe.com/flex/spark" xmlns:com = "com.*"
			   xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

	<fx:Script>
		<![CDATA[
			protected function rt_resultHandler(event:Event):void
			{
				// TODO Auto-generated method stub
			}
		]]>
	</fx:Script>

	<fx:Declarations>
		<!-- Place non-visual elements (e.g.,services,value objects) here -->
		<com:Remote id="rt" result="rt_resultHandler(event)"/>
	</fx:Declarations>
</s:Application>
