使用ActionScript 为MenuBar 控件的dataProvider 属性分配一个Collection 对象（例如
ArrayCollection 或者XMLListCollection）

 

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" creationComplete="initApp(event)">

<mx:MenuBar id="menu" dataProvider="{menu_dp}"/>

<mx:Script>
<![CDATA[

import mx.collections.ArrayCollection;
import mx.events.FlexEvent;

[Bindable]
private var menu_dp:ArrayCollection;

private function initApp(evt:FlexEvent):void {
 var temp:Array = new Array();
 var subNodes:ArrayCollection = new ArrayCollection([
  {label:"New"},{label:"Open"},{label:"Close",enabled:false}
 ]);
 
 temp.push({label:"File",children:subNodes});
 temp.push({label:"Edit"});
 temp.push({label:"Source"});
 
 subNodes = new ArrayCollection( [
  {label:"50%", type:"radio", groupName:"one"},
  {label:"100%", type:"radio",groupName:"one",selected:true},
  {label:"150%",type:"radio",groupName:"one"}
 ]);
 
 temp.push({label:"View",children:subNodes});
 menu_dp = new ArrayCollection(temp);
}

]]>
</mx:Script>
</mx:Application>
