Description

GtkAccessible provides an interface for describing a UI element, like a GtkWidget, in a way that can be consumed by Assistive Technologies, or “AT”. Every accessible implementation has:

a “role”, represented by a value of the GtkAccessibleRole enumeration
an “attribute”, represented by a set of GtkAccessibleState, GtkAccessibleProperty and GtkAccessibleRelation 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 “visible” property.

Functions

gtk_accessible_get_accessible_role ()

gtk_accessible_get_accessible_role (GtkAccessible *self);

Retrieves the GtkAccessibleRole for the given GtkAccessible.

Parameters
