How to get Tabnavigator index value when I click TabControl ?

I am used Canvas on as in Tabnavigator.

mx:TabNavigator id="tnJadwal" right="10" left="10" top="10" bottom="10"
tabWidth="50">
        <mx:Canvas label="Senin" width="100%" height="100%"></mx:Canvas>
        <mx:Canvas label="Selasa" width="100%" height="100%"></mx:Canvas>
        <mx:Canvas label="Rabu" width="100%" height="100%"></mx:Canvas>
        <mx:Canvas label="Kamis" width="100%" height="100%"></mx:Canvas>
        <mx:Canvas label="Jumat" width="100%" height="100%"></mx:Canvas>
</mx:TabNavigator>
