[flexcoders] Flex 2 - Event after a screen is fully constructed, but before it can be seen

[Libby]

Hello flexSperts  : )

I want to do some prep work within my screen that requires all parts
of it to be constructed first. Is there a built-in event that fires
just before the screen is visible, but guarantees all parts are
constructed, that I could listen for? Maybe it occurs right after I
addChild() to my viewStack? If so, what would that event be? If not,
how do you guys handle this situation?

Thanks,
Libby
