AccessibleIF

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

Every accessible implementation has:

- a “role”, represented by a value of the [enum@Gtk.AccessibleRole] enumeration - an “attribute”, represented by a set of [enum@Gtk.AccessibleState], [enum@Gtk.AccessibleProperty] and [enum@Gtk.AccessibleRelation] 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 [property@Gtk.Widget:visible] property.

interface AccessibleIF {

GtkAccessible* getAccessibleStruct(bool transferOwnership);

void* getStruct();

static GType getType();

GtkAccessibleRole getAccessibleRole();

void resetProperty(GtkAccessibleProperty property);

void resetRelation(GtkAccessibleRelation relation);

void resetState(GtkAccessibleState state);

void updatePropertyValue(GtkAccessibleProperty[] properties, Value[] values);

void updateRelationValue(GtkAccessibleRelation[] relations, Value[] values);

void updateStateValue(GtkAccessibleState[] states, Value[] values);

}
