I am using a scrolllist that contains 6 items, 4 of which are visible. It is a horizontal list and non-circular. I'd like to have a couple of indicator items, one to the left and another to the right of the scrolllist to show whether there are items that are not currently visible. Maybe I'll even make these clickable and then auto-scroll left or right. I don't currently see a way to know what items are in view at the moment and someone has already asked this here:

scrollList2UpdateItem() doesn't do anything useful here because it just tells you that you need to update something that is shortly going to be visible.
