How do I execute a function when the UI tabs have been tabified?


What I really would like is for the jQuery UI "tabsshow" event
(alternatively a tabsinitialized event) to fire when the tabs have
been initialized (we are showing a tab after all, aren't we?).
But since it doesn't, is there another way to execute some kind of
init function when the tabs have loaded?
Best regards,
