Accessible interface.
Gtk::Accessible provides an interface for describing a UI element, like a Gtk::Widget, in a way that can be consumed by Assistive Technologies, or “AT”. Every accessible implementation has:
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 Gtk::Widget::property_visible().
