EExtension objects can be tacked on to any GObject instance that implements the EExtensible interface. A GObject type can be made extensible in two steps:
Add the EExtensible interface when registering the GType. There are no methods to implement.
1 |
Load extensions for the class at some point during GObject initialization. Generally this should be done toward the end of the initialization code, so extensions get a fully initialized object to work with.

void
e_extensible_load_extensions (EExtensible *extensible
);
Creates an instance of all instantiable subtypes of EExtension which
target the class of extensible
. The lifetimes of these newly created
EExtension objects are bound to extensible
such that they are finalized
when extensible
is finalized.

GList * e_extensible_list_extensions (EExtensible *extensible
,GType extension_type
);
Returns a list of EExtension objects bound to extensible
whose
types are ancestors of extension_type
. For a complete list of
extension objects bound to extensible
, pass E_TYPE_EXTENSION
.
The list itself should be freed with g_list_free()
. The extension
objects are owned by extensible
and should not be unreferenced.
a list of extension objects derived from extension_type
