Flex中TabNavigator设置Tabs样式

1、设计思路

（1）设计一个TabNavigator，其中包含两个Tabs；

（2）设置Tabs样式

2、设计源码

Tabs.mxml：

<?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"
			   width="100%" height="100%"
			   >
	<fx:Declarations>
		<!-- Define custom colors for use as fills. -->
		<mx:SolidColor id="sc1" color="0xADFF2F" alpha=".8"/>
		<mx:SolidColor id="sc2" color="0xADD8E6" alpha=".6"/>
		
		<!-- Define custom Strokes for the columns. -->
		<mx:SolidColorStroke id="s1" color="0xADFF2F" weight="2"/>
		<mx:SolidColorStroke id="s2" color="0xADD8E6" weight="2"/>
	</fx:Declarations>
	
	<fx:Style>
		@namespace s "library://ns.adobe.com/flex/spark";
		@namespace mx "library://ns.adobe.com/flex/mx";
		.myTabs{
			color:#FFFFFF;
			font-weight:bold;
			background-color:#6495ED;
		}
		.myTextTabs{
			color:#8B0000;
			background-color:#97FFFF;
			font-weight:bold;
		}
		mx|TabNavigator{
			tab-style-name:"myTabs";
			first-tab-style-name:"myTabs";
			last-tab-style-name:"myTabs";
			selected-tab-text-style-name:"myTextTabs";
		}
	</fx:Style>
	
	<fx:Script>
		<![CDATA[
			import mx.collections.ArrayCollection;
			
			[Bindable]
			//学生数据绑定
			private var studentArray:ArrayCollection = new ArrayCollection([
				{sno:"2013010101",math:"96"},
				{sno:"2013010102",math:"89"},

				{sno:"2013010110",math:"89"}
			]);
			
			[Bindable]
			//教师数据绑定
			private var teacherArray:ArrayCollection = new ArrayCollection([
				{tno:"2013010101",tscore:"96"},
				{tno:"2013010102",tscore:"99"},
				{tno:"2013010103",tscore:"77"},
				{tno:"2013010104",tscore:"70"},
				{tno:"2013010105",tscore:"98"},
				{tno:"2013010106",tscore:"79"},

				{tno:"2013010109",tscore:"80"},
				{tno:"2013010110",tscore:"79"}
			]);
		]]>
	</fx:Script>
	
	<mx:VBox width="100%" height="100%" paddingBottom="10" paddingLeft="10" paddingRight="10" paddingTop="10">

					</mx:HBox>
				</mx:VBox>
			</s:NavigatorContent>
		</mx:TabNavigator>
	</mx:VBox>
</s:Application>

3、设计说明

（1）tab-style-name：设置所有tabs的样式类

（2）first-tab-style-name：设置第一个tabs的样式类

（3）last-tab-style-name：设置最后一个tabs的样式类

（4）selected-tab-text-style-name：设置选中的tabs中的text样式类

4、设计结果

（1）初始化时结果

（2）切换tabs
