Thinking of it, isn't the onscroll event meant to handle how the scrolled
area is repainted? I'm not talking about repainting the scrollbar itself but
the area it is supposed to control. If I want fe. to update only the record
number or page number while scrolling and repaint the full page/table when
scrolling stops, there is no reason to invalidate the whole area. Actually,
I'm still having a problem finding an example where Tscrollbar has to
invalidate the whole or part of the parent area.
