关于ObjectProxy

该类提供跟踪对此代理管理的项目进行的更改的功能。任何数量的对象都可使用 addEventListener() 方法“侦听”对此对象的更改。

此类为代理类。可以监听代理的Object对象是否进行更改:

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
creationComplete="initApp();">
<s:layout>
<s:BasicLayout/>
</s:layout>
<s:Button x="139" y="444" label="按钮" click="button1_clickHandler(event)"/>
<fx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
import mx.controls.Alert;
import mx.events.PropertyChangeEvent;
import mx.utils.ObjectProxy;
private var obj:Object;
private var o:ObjectProxy;
private function initApp():void
{
obj=new Object();
o=new ObjectProxy(obj);
o.name="@";
o.age=18;
o.aa="sa";
o.addEventListener(PropertyChangeEvent.PROPERTY_CHANGE,ChangeHandler);
}
protected function button1_clickHandler(event:MouseEvent):void
{
o.name="ok";
}
private function ChangeHandler(e:PropertyChangeEvent):void
{
trace("发生变化");
}
]]>
</fx:Script>
</s:Application>

也可以用于ArrayCollection里面的设置:

private var dataArr:ArrayCollection=new ArrayCollection
([
new ObjectProxy(Object({location:"CF",id:"data/gril.png", name:"刘德华", skill:"data/idea.png" ,fight:10000, grade:"100" ,shot:"100", onbreak:"100" ,speed:"10" ,strongth:"100", block:"100", save:"0.5"})),
new ObjectProxy(Object({location:"SS",id:"data/boy.png", name:"成龙", skill:"data/idea.png" ,fight:10000, grade:"100" ,shot:"100", onbreak:"100" ,speed:"20" ,strongth:"100", block:"100", save:"0.5"})),
new ObjectProxy(Object({location:"RMF",id:"data/gril.png", name:"李连杰", skill:"data/idea.png" ,fight:10000, grade:"100" ,shot:"100", onbreak:"100" ,speed:"30" ,strongth:"100", block:"100", save:"0.5"})),
new ObjectProxy(Object({location:"RCM",id:"data/gril.png", name:"张学友", skill:"data/idea.png" ,fight:10000, grade:"100" ,shot:"100", onbreak:"100" ,speed:"40" ,strongth:"100", block:"100", save:"0.5"})),
new ObjectProxy(Object({location:"LCM",id:"data/boy.png", name:"张国荣", skill:"data/idea.png" ,fight:10000, grade:"100" ,shot:"100", onbreak:"100" ,speed:"50" ,strongth:"100", block:"100", save:"0.5"})),
new ObjectProxy(Object({location:"LMF",id:"data/gril.png", name:"李宗盛", skill:"data/idea.png" ,fight:10000, grade:"100" ,shot:"100", onbreak:"100" ,speed:"60" ,strongth:"100", block:"100", save:"0.5"}))
]);
