public interface Accessible : Object
GtkAccessible provides an interface for describing a UI element, like a Widget, in a way that can be consumed by Assistive Technologies, or “AT”.
Every accessible implementation has:
- a “role”, represented by a value of the AccessibleRole enumeration
- an “attribute”, represented by a set of AccessibleState, AccessibleProperty and AccessibleRelation values
The role cannot be changed after instantiating a 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 Widget visibility changes, the gtk_accessible_state_hidden state will also change to reflect the visible property.
