Details

The gtk-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 widgets, including the gtk-spin-button, gtk-viewport, and gtk-range widget, which is a base class for the gtk-scrollbar, and gtk-scale widgets.

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