``GtkATContext`` is an abstract class provided by GTK to communicate to
platform-specific assistive technologies API.

Each platform supported by GTK implements a ``GtkATContext`` subclass, and
is responsible for updating the accessible state in response to state
changes in ``GtkAccessible``\.

   .. classmethod:: create(accessible_role: ~gi.repository.Gtk.AccessibleRole, accessible: ~gi.repository.Gtk.Accessible, display: ~gi.repository.Gdk.Display) -> ~gi.repository.Gtk.ATContext | None

      Creates a new ``GtkATContext`` instance for the given accessible role,
      accessible instance, and display connection.

      The ``GtkATContext`` implementation being instantiated will depend on the
