Declaration
void
g_object_class_override_property (
GObjectClass* oclass,
guint property_id,
const gchar* name
)
Description
Registers property_id as referring to a property with the name
name in a parent class or in an interface implemented by oclass.
This allows this class to “override” a property implementation in
a parent class or to provide the implementation of a property from
an interface.
Internally, overriding is implemented by creating a property of type
GParamSpecOverride; generally operations that query the properties of
the object class, such as g_object_class_find_property() or
g_object_class_list_properties() will return the overridden
property. However, in one case, the construct_properties argument of
the constructor virtual function, the GParamSpecOverride is passed
instead, so that the param_id field of the GParamSpec will be
correct. For virtually all uses, this makes no difference. If you
need to get the overridden property, you can call g_param_spec_get_redirect_target().
