Spark Tab bar rollover index.. flex4 problem

Hi Experts,

       I am using a the spark tabbar and gave a view stack as dataprovider.....in the view stack there are  n elements ...and each element has a panel....

 

my code would be  some thing like this....

 

 

<s:tabbar dataprovider = {viewstck-id}  height="100%" width="100%"/>

<viewstack id="viewstck-id">

    <navigatorContent >

         <s:panel title="title - 1"/>

     </navigatorContent >

     <navigatorContent >

         <s:panel title="title - 2"/>

     </navigatorContent >\

     <navigatorContent >

         <s:panel title="title - 3"/>

     </navigatorContent >

</viewstk>

 

My requirement is something like this......initially the panel of the select tab should show the its own title..suppose if we are on tab-1 the title should be title-1 ...but when we roll over our mouse on tab-2 the title of the panel in tab-1 should be changed to tittle-2  and if the mouse is on tab3 the  title of the panel in tab-3 should be changed to tittle-3  and on roll out it should be changed to selected tab's panel's title , i.e. title-1....and in similar way it should work for all the tabs.....

 

So is there any way to get the  get the rollOverIndex of the tab Or some one please provide me a solution.

Well at first I would suggest to give the navigator-content elements ids and to place the label there too.
Have a look at the sample code here:

If you want your described effect, I currently see two main options:

1.  I would suggest to create a custom TabBarSkin and within this you define your own TabBarButtonSkin. Inside this you should be able to navigate

ViewStack(ButtonBar(ButtonBarButton(hostComponent).parent).dataProvider).rawChildren.getChildAt(0).label = "hurz!";

I would debug this however, as this might not be 100% correct, It's just in order to give you the idea.

2. I would create a custom TabBarButtonSkin that fires custom events on rollover/rollout. It is important that you set the bubbling property of these events to true, so they can be caught up the component tree. You then register some listeners on the TabBar and handle the updating of tab-labels accordingly.

Note: small change
if the mouse is on tab3 the  title of the panel in tab-3 should be changed to tittle-1
