136 GtkScrollbar

Base class for GtkHScrollbar and GtkVScrollbar

136.1 Overview

The <gtk-scrollbar> widget is an abstract base class for <gtk-hscrollbar> and <gtk-vscrollbar>. It is not very useful in itself.

The position of the thumb in a scrollbar is controlled by the scroll adjustments. See <gtk-adjustment> for the fields in an adjustment - for <gtk-scrollbar>, 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).

136.2 Usage
