None

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 widgets, 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.

The "changed" signal

lambda (adjustment)    :no-recurse      

Emitted when one or more of the adjustment properties have been changed, other than the value property.

The "value-changed" signal
