subscribe to the TabNavigators "click" event. From here, execute a validation routine based on the last known tab clicked (ie default is tab0, then if user clicks tab1, then update a var to indicate such).
Validate that tab, if it fails, then simply fire an exception routine (ie popup) and selectedIndex = failedTab. The end-user may experience a "flicker" between the two tabs based on how long it takes to compute the validation routine. this is the "quick and easy" way. If you want to prevent a user from accessing the tab, then you may have to extend the TabNavigator and over-ride the various methods associated to that class. I can't remember off the top of my head what the TabNavigator uses in terms of click, but i'd bet the farm it uses SimpleButton. I'd love to post the code for code, line by line here but i'm a bit swamped at present but the above is based on theory (especially if it works similiar to the Accordion) On 6/21/05, Mika Kiljunen <[EMAIL PROTECTED]> wrote: > > > > Hi, > > I could use some help with tabnavigator.
