5 Base class for GtkHScrollbar and GtkVScrollbar
7 <!-- ##### SECTION Long_Description ##### -->
9 The #GtkScrollbar widget is an abstract base class for #GtkHScrollbar and
10 #GtkVScrollbar. It is not very useful in itself.
14 The position of the thumb in a scrollbar is controlled by the scroll
15 adjustments. See #GtkAdjustment for the fields in an adjustment - for
16 #GtkScrollbar, the "value" field represents the position of the
17 scrollbar, which must be between the "lower" field and "upper -
18 page_size." The "page_size" field represents the size of the visible
19 scrollable area. The "step_increment" and "page_increment" fields are
20 used when the user asks to step down (using the small stepper arrows)
21 or page down (using for example the PageDown key).
