\section{Interfaces}{GtkScrollbar implements
AtkImplementorIface, \code{\link{GtkBuildable}} and \code{\link{GtkOrientable}}.}
\section{Detailed Description}{The \code{\link{GtkScrollbar}} widget is an abstract base class for \code{\link{GtkHScrollbar}} and
\code{\link{GtkVScrollbar}}. It is not very useful in itself.
The position of the thumb in a scrollbar is controlled by the scroll
adjustments. See \code{\link{GtkAdjustment}} for the fields in an adjustment - for
\code{\link{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).}
\section{Structures}{\describe{\item{\verb{GtkScrollbar}}{
The \code{\link{GtkScrollbar}} struct does not contain any public data.
