目前常用的Flex4的导航容器有TabNavigator,Accordion,ViewStack,目前Flex4的大部分可视UI组件都被替换为<s:开头【也通常叫Spark组件】取代了Flex3的<mx:标签
首先来说下TabNavigator

如果想要换成是如下图的这种导航
只需要将<mx:TabNavigator换成<mx:Accordion对应的标签即可
最后要说明的是ViewStack可不一样,如果我们直接将<mx:TabNavigator换成<mx:ViewStack那么只能显示一项的内容并且也没有导航条,需要添加一行导航条代码即可
在<mx:TabNavigator代码块之前加上<mx:LinkBar dataProvider="{mynavigator}" />
或者是<mx:TabBar dataProvider="{mynavigator}" />或者是
<s:ButtonBar dataProvider="{mynavigator}" />
或者是<mx:ToggleButtonBar dataProvider="{mynavigator}"/>
都会显示出很好的导航条效果,这个mynavigator指的是<mx:ViewStack id="navigator"的这个ID了

ButtonBar和ToggerButtonBar和的效果图一样
