title: Flex 4: Determining the index (not the selectedIndex) for a TabBar mouseOver
body: <p>I have an application where I'm trying to update the String for a Label's text property, based on the tab which user has the mouse over. I've constructed a simple example displaying how I would process the eventHandler function if I <em>was</em> going to use the selectedIndex property, however it's the tab that has mouse focus, which may or may not be the selectedItem, that I'd like to reference and I haven't been able to figure out a way to do it.</p>
  
  <p>So here is the example:
     
      
      
          
      
      
          
      </p>
  
  <pre><code>&lt;s:Label 
      id="descriptionLabel"
      /&gt;
  &lt;s:TabBar 
      id="audioTB"
      dataProvider="{audioVS}"
      mouseOver="audioTB_mouseOverHandler(event)"
      rollOut="audioTB_rollOutHandler(event)"
      /&gt;
  &lt;mx:ViewStack 
      id="audioVS"
      &gt;
      &lt;!--- Menu1 --&gt;
      &lt;s:NavigatorContent
          id="audioNC1"
          label="Audio Menu 1"
          &gt;
          &lt;mx:DataGrid
              id="audioDG1"
              /&gt;
      &lt;/s:NavigatorContent&gt;
      &lt;!--- Menu2 --&gt;
      &lt;s:NavigatorContent
          id="audioNC2"
          label="Audio Menu 2"
          &gt;
          &lt;mx:DataGrid
              id="audioDG2"
              /&gt;
      &lt;/s:NavigatorContent&gt;
      &lt;!--- Menu3 --&gt;
      &lt;s:NavigatorContent
          id="audioNC3"
          label="Audio Menu 3"
          &gt;
          &lt;mx:DataGrid
              id="audioDG3"
              /&gt;
      &lt;/s:NavigatorContent&gt;
  &lt;/mx:ViewStack&gt;
  &lt;/s:Application&gt;
  </code></pre>
  
  <p>Any suggestions would be greatly appreciated.</p>
  
  <p>Thanks,
