I don't think you will be able to update the scroll-bar positions. The scroll functionality that is implemented for panel objects is limited to automatic scrolling and the racket GUI code would have to be updated to allow changing it programmatically. BTW, I am looking forward to being proven wrong on this, as I could use the functionality myself :-) Alex. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
