flex tabnavigator tabs click event

Question

I have a <mx:TabNavigator> which has some <s:NavigatorContent> tags as children . I want the tabs to dispatch an event when I click them . I tried the "click" event in NavigatorContent but it didn't do anything . anyone has any experience with it? thanks

Answer 1

I believe you want the change event.

It is inherited from the ViewStack container: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/mx/containers/ViewStack.html#event:change

Answer 2

Hi i believe using the show event might do what you want?

i wanted an event triggered when the particular is shown, and i wanted a different action for each navigatorcontent of my tabnavigator.

hope it helps someone :)
