module Gtk::Accessible

Overview

Gtk::Accessible is an interface for describing UI elements for Assistive Technologies.

Every accessible implementation has:

• a “role”, represented by a value of the Gtk::AccessibleRole enumeration
• an “attribute”, represented by a set of Gtk::AccessibleState, Gtk::AccessibleProperty and Gtk::AccessibleRelation values

The role cannot be changed after instantiating a Gtk::Accessible implementation.

The attributes are updated every time a UI element's state changes in a way that should be reflected by assistive technologies. For instance, if a Gtk::Widget visibility changes, the %GTK_ACCESSIBLE_STATE_HIDDEN state will also change to reflect the Gtk::Widget#visible property.
