Gtk.Accessible – gtk4 – Vala Binding Reference

Description:

[ CCode ( type_cname = "GtkAccessibleInterface" , type_id = "gtk_accessible_get_type ()" ) ]
public interface Accessible : Object

`GtkAccessible` is an interface for describing UI elements for Assistive Technologies.

Every accessible implementation has:

a “role”, represented by a value of the [[email protected]] enumeration
an “attribute”, represented by a set of [[email protected]], [[email protected]] and [ [email protected]] values

The role cannot be changed after instantiating a `GtkAccessible` 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 `GtkWidget` visibility changes, the gtk_accessible_state_hidden state will also change to reflect the [[email protected]:visible] property.
