FUCK FLEX菜单的几种dataProvider

1：数组Array

<fx:Script>
??<![CDATA[
??import mx.collections.ArrayCollection;
??? [Bindable]public var menuDataTypeArray : Array =
??? [
???{label:'File',children:[ { label:'New' },{ label:'Open' } ] },
???{label:'Edit',children:[{label:'Undo'},{label:'Redo'}]}
???? ];???
??]]>
?</fx:Script>>

<mx:MenuBar dataProvider="{menuDataTypeArray}"/>

嵌套数组默认是查找名为children的嵌套数组

2：ArrayCollection

?? <fx:Script>
??<![CDATA[
??import mx.collections.ArrayCollection;
??? [Bindable]public var menuDataTypeArray : Array =
??? [
???{label:'File',{label:'Redo'}]}
???? ];???
??
??[Bindable]private var menuDataTypeArrayList:ArrayCollection = new ArrayCollection(menuDataTypeArray);
??]]>
?</fx:Script>
?<mx:MenuBar dataProvider="{menuDataTypeArrayList}" />

3:使用MXML标签<fx:Array>

<fx:Array id="menuData">
????<fx:Object label="File">
?????<fx:children>
??????<fx:Array>
???????<fx:Object label="Start"/>
??????</fx:Array>
?????</fx:children>
????</fx:Object>
???</fx:Array>

?

ArrayCollection 包装

<mx:ArrayCollection id="menuData">

<fx:Array >
????<fx:Object label="File">
?????<fx:children>
??????<fx:Array>
???????<fx:Object label="Start"/>
??????</fx:Array>
?????</fx:children>
????</fx:Object>
???</fx:Array>

</mx:ArrayCollection>

4:XML

<fx:XML id="menuDataXML">

?????<submenu label="Edit"/>
????</menuitem>
????<menuitem label="View">
