A base class for GtkHScrollbar and GtkVScrollbar
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
page_size field represents the
size of the visible scrollable area. The
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).
