SetScrollBar()

    USAGE

        void SetScrollBar(ListInfo)

    FUNCTION

        This modifies and redraw the scroll bar for the list defined by the ListInfo
        structure. This is necessary when the list size has changed, or the position
        of the TopDisplayItem has moved.
        DrawList, ScrollList, SizeList, ClickList, InsertListItem, and RemoveListItem
        all readjust the scroll bar, so you need not call SetScrollBar when these
        functions are called.

    INPUTS

        ListInfo = Pointer to ListInfo structure that describes the list.

    RESULT

        none (void)
