You cannot add a ScrollBar to the view that the scrollbar is supposed to
scroll. Just think about it! :-)
In any case, for questions such as these, I would suggest to take any
random Haiku application or preflet that has a list view with scroll bars,
and just look at the code. The Sounds preflet seems like a good choice.
