GtkHScrollbar, GtkVScrollbar

Description

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).

GtkScrollbar has no own method; have a look at GtkRange instead.

If you want to add scrollbars to a GtkTextView or a GtkTreeView, you should use a GtkScrolledWindow.
