Roger Whitcomb updated PIVOT-772:
---------------------------------
Attachment: Scroll2.java
Hi Noel,
If you use the new attached "Scroll2.java" and choose "Multiple Lines per
Append", you can see the behavior very clearly. Once it finishes (and the
buttons are enabled again), you will see line 34 at the bottom of the TextArea,
but if you move the scroll bar down you will see that there are lines 35-38
that are still not visible (and a blank line underneath that as well). So,
even though we are consistently getting the character bounds of the very last
character every time, the scroll doesn't quite scroll enough so that by the end
we still have five lines that are not visible and could still be scrolled into
view with the scroll bar.
Thanks!
