FLEX3组件定制

组件中，所有的ID都是可以对外访问的。但是组件中的子控件，是无法提供对外事件支持的，这时需要做事件的转发功能，如下：

<?xml version="1.0" encoding="utf-8"?>
<mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" width="292" height="226">
 <mx:Metadata>
  [Event(name="myComponentTextChange", type="flash.events.Event" )]
 </mx:Metadata>

<mx:Script>
 <![CDATA[
  [Bindable("text")]
  [Inspectable(defaultValue="hello word")] 
  public function set myComponentText(value:String):void
  {
  inputText.text=value
  }
  public function get myComponentText():String{
  return inputText.text
  }
  
 ]]>
</mx:Script>
 <mx:TextArea id="inputText" change="this.myComponentText=inputText.text; this.dispatchEvent(new Event('myComponentTextChange'))" width="264" height="183" />
</mx:TitleWindow>

 

--------------------------------------------------------------

 <?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:wxsr="components.*" xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
 <wxsr:TestComponent id="testComponent" enterFrame="trace(testComponent.myComponentText)" myComponentTextChange="trace('------')">
  
 </wxsr:TestComponent>
</mx:Application>
