Gtk::Adjustment Class Reference

#include <adjustment.h>

Inheritance diagram for Gtk::Adjustment:


List of all members.

Detailed Description

A class representing an adjustable bounded value.

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 gtkmm widgets, including Gtk::SpinButton, Gtk::Viewport, and Gtk::Range (which is a base class for Gtk::HScrollbar, Gtk::VScrollbar, Gtk::HScale, and Gtk::VScale).

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

The owner of the Gtk::Adjustment typically calls the value_changed() and changed() functions after changing the value and its bounds. This results in the emission of the "value_changed" or "changed" signal respectively.
