Interfaces

GtkScrollbar implements AtkImplementorIface, GtkBuildable and GtkOrientable.

Detailed 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).
