first of all, thank you very very much for your answers,, it is really very
helpful ...I 'am hapyy
so, here in the function changed i can do this :
private function changed(evt:IndexChangedEvent):void{
trace("Tab changed from (" + evt.oldIndex + ") to (" +
evt.newIndex + ")");
if(oldIndex ==0){ // when we clik in
the second tab (tab which has index1) Alert.show(we
cliked in the tab1) } else
Alert.show(we cliked in the tab0)
}
Give me your opinion please ?????
Thanks :)
Nice afternoon :)

The oldIndex is the tab that was current before you click on another tab. So
if you have two tabs (like in the demo) with the indices of 0 and 1 and you
click on the second tab, the oldIndex will be zero (0) and the new tab will be
one (1). If you then click on tab 1, oldIndex will be 1 and newIndex will be 0.
The demo app. posted outputs that information in the trace window.
