There are several other posts about this in the same archived thread
and others. I almost think this is a FAQ.

Hello,
I have two problems in my current app that are very similar.
1. I have an NSTextView that is continuously being updated with data
(think telnet client). When the data comes in, I append it to the
text view and scroll it to visible. This is acceptable behavior IF
and only IF the user is already scrolled all the way to the bottom;
How do I tell if the user has scrolled the view up?
2. I have an NSTableView that is continuously being updated with data
(I have no analogy here, sorry). When new rows are added or delete
(in sorted order, so they could be added above or below), I maintain
the user selected row and scroll it to visible-- this is also
acceptable behavior.. The problem is when the user has a selected row
and then scrolls the table to look at other rows. When data comes in,
it automatically scrolls the table back so his original selected row
is visible.
These are both VERY annoying usability wise. So, is there a way to
tell if
1. In the case of NSTextView, the last text of the view is visible
AND/OR if the scroll bar is not at it's vertical extreme?
2. In the case of NSTableView, the currently selected row is visible?
Thanks,
Rick Bischoff
