public class Adjustment : InitiallyUnowned

The Adjustment object represents a value which has an associated lower and upper bound, together with step and page increments, and a page size.

It is used within several GTK+ widgets, including SpinButton, Viewport, and Range (which is a base class for Scrollbar and Scale).

The Adjustment object does not update the value itself. Instead it is left up to the owner of the Adjustment to control the value.
