Flex中TabNavigator设置Tabs样式思路及源码

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：

复制代码 代码如下:

<?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%"
>
<fx:Declarations>
<!-- Define custom colors for use as fills. -->
<mx:SolidColor color="0xADFF2F" alpha=".8"/>
<mx:SolidColor color="0xADD8E6" alpha=".6"/>

<!-- Define custom Strokes for the columns. -->
<mx:SolidColorStroke color="0xADFF2F" weight="2"/>
<mx:SolidColorStroke 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"},

]);

//教师数据绑定

{tno:"2013010109",tscore:"80"},
{tno:"2013010110",tscore:"79"}
]);
]]>
</fx:Script>

</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
