Flex 动态换肤

    可能很多人在写Flex程序的时候为了界面的美化，都会用到css，这里有一个动态换肤的实现。

 

    原理就是将各种不同的css文件先编译成swf,然后用StyleManager类的loadStyleDeclarations方法加载换肤的swf。代码如下：

 

 

<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" 
	 width="100" height="16" >
	<mx:LinkButton width="16" height="16" color="#ff0000" icon="@Embed('assets/png/springbt.png')"
		 click="onChangeStyle(event)" x="0" id="spring" toolTip="春季主题"/>
	<mx:LinkButton width="16" height="16" color="#ff0000" icon="@Embed('assets/png/summerbt.png')"
		 click="onChangeStyle(event)" x="17" id="summer" toolTip="夏季主题"/>
	<mx:LinkButton width="16" height="16" color="#00ff00" icon="@Embed('assets/png/autumnbt.png')"
		 click="onChangeStyle(event)" x="34" id="autumn" toolTip="秋季主题"/>
	<mx:LinkButton width="16" height="16" color="#ff0000" icon="@Embed('assets/png/winterbt.png')"
		 click="onChangeStyle(event)" x="51" id="winter" toolTip="冬季主题"/>
	<mx:LinkButton width="16" height="16" color="#ff0000" icon="@Embed('assets/png/default.PNG')"
		 click="onChangeStyle(event)" x="68" id="defult" toolTip="默认主题"/>
	<mx:Script>
		<![CDATA[
			import com.yyhy.webgis.model.ModelLocator;
		
			private var __model:ModelLocator = ModelLocator.getInstance();
			
			private function onChangeStyle(event:MouseEvent):void
			{
				if(event.currentTarget == spring)
				{
					__model.selectskin = "Spring";
					StyleManager.loadStyleDeclarations("assets/skins/color/Spring.swf");
				}
				else if(event.currentTarget == summer)
				{
					__model.selectskin = "Summer";
					StyleManager.loadStyleDeclarations("assets/skins/color/summer.swf");
				}
				else if(event.currentTarget == autumn)
				{
					__model.selectskin = "Autumn";
					StyleManager.loadStyleDeclarations("assets/skins/color/autumn.swf");
				}					
				else if(event.currentTarget == winter)
				{
					__model.selectskin = "Winter";
					StyleManager.loadStyleDeclarations("assets/skins/color/winter.swf");
				}
				else if(event.currentTarget == defult)
				{
					__model.selectskin = "Start";
					StyleManager.loadStyleDeclarations("assets/skins/color/start.swf");
				}
				else
				{
					__model.selectskin = null;
					return;
				}
			}			
		]]>
	</mx:Script>
</mx:Canvas>

嗯，是的，这个类应该是继承cairngorm框架的

ModelLocator是自己定义的么？
