     The 'GtkScrollbar' widget is an abstract base class for
     'GtkHScrollbar' and 'GtkVScrollbar'. It is not very useful in
     itself.

     The position of the thumb in a scrollbar is controlled by the
     scroll adjustments. See 'GtkAdjustment' for the fields in an
     adjustment - for 'GtkScrollbar', 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).
