 22deferred class GTK_SCROLLBAR
 23	-- The GTK_SCROLLBAR widget is a deferred (abstract) base class for
 24	-- GTK_HSCROLLBAR and GTK_VSCROLLBAR.
 25
 26	-- The position of the thumb in a scrollbar is controlled by the
 27	-- scroll adjustments. See GTK_ADJUSTMENT for the fields in an
 28	-- adjustment - for GtkScrollbar, the "value" field represents the
 29	-- position of the scrollbar, which must be between the "lower"
 30	-- field and "upper - page_size." The "page_size" field represents
 31	-- the size of the visible scrollable area. The "step_increment"
 32	-- and "page_increment" fields are used when the user asks to step
 33	-- down (using the small stepper arrows) or page down (using for
 34	-- example the PageDown key).
