## Description

The GtkScrollbar widget is a horizontal or vertical scrollbar, depending on the value of the “orientation” property.

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 properties when the user asks to step down (using the small stepper arrows) or page down (using for example the PageDown key).
