Thanks for your replies.

It was a bit irritating to deal with it. Something was really odd with TabNavigator class in Flex 3. I have had some issues with indexes adding children at concrete positions – “addChildAt” worked strangely for me. Anyway, thanks for your help in this particular case.

Hi. Good post. My problem is that i nned to capture the IndexChangedEvent.CHANGE but at enter, look this line:
tabNav.addEventListener(IndexChangedEvent.CHANGE, functionTest, true);
The last boolean value, indicate that i need to capture before change the tab, but don’t work, because the function “functionTest” receive a Event (not a IndexChangedEvent) and the parameters newIndex, oldIndex are lost. Anyone know how to do this, without an MouseEvent.CLICK ?
Thanks

@JC, It would help if we have some sample code to look at. Cheers.

Can you put a simplified example up with the source?

I have run into an issue with the CHANGE event for the TabNavigator.

I have a TabNavigator with several Canvas children that each contain form elements. When the user clicks to go to the next tab, the CHANGE handler calls some validation. If the validation returns false, then the SelectedIndex is set back to the previous tab. This works fine, but once the user fixes his mistakes and clicks to go to the next tab again, the CHANGE event does not fire. For example, they are on tab 0 and click on tab 1, if they didn’t fill out everything on tab 0, the CHANGE event sets the SelectedIndex back to 0 and displays an Alert. This works. However, once they fill out everything on tab 0 and click on tab 1 again, tab 1 is displayed, but the CHANGE event does not fire.

Any ideas?

Thanks,
JC

Thanks for your post. I had a same problem. I used ‘TabIndexChange’ event, but it didn’t work. So, appreciating to your post, I use ‘Chang’ event and solve my problem.

I have seen more than a few people getting confused with this. Many wouldnt realize in first instance that which event they should cast to when they pick it up. It would have been better if the event was called indexChanged or something on those lines rather than a duplicate name CHANGE.

definitely best off typing it as…

IndexChangedEvent.CHANGE

It’s confusing like anything else you don’t know or haven’t used before. Once used it makes perfect sense. when the Index in your TabNavigator changes it fires a ‘IndexChangedEvent.CHANGE’. That makes perfect sense to me.
