Interface

GtkAccessible

Description [src]

interface Gtk.Accessible : GObject.Object

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

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 GtkWidget:visible property.

Prerequisite

In order to implement Accessible, your type must inherit from GObject.
