-- * Detail
--
-- | The 'Scrollbar' widget is an abstract base class for
-- 'Graphics.UI.Gtk.Scrolling.HScrollbar' and
-- 'Graphics.UI.Gtk.Scrolling.VScrollbar'. It is not very useful in itself.
--
-- The position of the thumb in a scrollbar is controlled by the scroll
-- adjustments. See 'Graphics.UI.Gtk.Misc.Adjustment' for the fields in an
-- adjustment - for
-- 'Scrollbar', the \"value\" field represents the position of the scrollbar,
-- which must be between the \"lower\" field and \"upper - page_size.\" The
-- \"page_size\" field represents the size of the visible scrollable area. The
-- \"step_increment\" and \"page_increment\" fields are used when the user asks
-- to step down (using the small stepper arrows) or page down (using for
-- example the PageDown key).
