I am confused, do you want to use the scrollbar for scrolling or the
mouse wheel?
I want to use the scrollbar because it provides visual feedback about
the location of the section of the visible data in a larger buffer of
displayable data.
You may hit the scrollbar position limits with really large data sets.
I prefer that the scrollbar perform this function
regardless of whether the mouse wheel is moved (with the mouse pointer
hovering over the scrollbar) or the scrollbar handle is dragged with the
mouse or the arrow or page up/down buttons are used. All methods should
to the same thing; move the data display in response to scrollbar events.
You can implement a common MoveTo method, which is called by both the
scrollbar and wheel events, optionally by key events. For non-scrollbar
events you should update the scrollbar position - what for itself may
trigger the scrollbar event (don't remember).
