flex自定义按钮肌肤

先看效果图：

其中Test.mxml为：

<?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:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">	                          			
	<fx:Declarations>
		<!-- 将非可视元素（例如服务、值对象）放在此处 -->
	</fx:Declarations>
	<mx:HBox horizontalCenter="0" verticalCenter="1">
		<s:Button id="rightButton"  skinClass="components.RightButtonSkin" />
		<s:Button id="cancelButton"  skinClass="components.CancelButtonSkin" />
		<s:Button id="newStyleButton"   skinClass="components.NewStyleButtonSkin"/>	
		<s:Button id="StyleButton"   skinClass="components.StyleButtonSkin"/>
	</mx:HBox>
</s:Application>

RightButtonSkin.mxml(确定按钮皮肤)：

	</s:states>

	<!-- border and fill -->
	<s:Rect id="rect" radiusX="4" radiusY="4" top="0" right="0"

		</s:stroke>
	</s:Rect>
	
	<!-- highlight on top -->
	<s:Rect radiusX="4" radiusY="4" top="2" right="2" left="2"
