13.10 Specifying additional properties for CLOS classes

Some properties are not exposed through GObject introspection facilities, but are rather present as a pair of functions (class_get_property, class_set_property). gobject-class metaclass supports such properties. For these properties to be included in automatically generated class definitions, they should be made known to the generator.

Definitions generator uses variable *additional-properties* to get this information.

Variable *additional-properties* contains a plist that maps GType names to a list of properties definitions (See define-g-object-class for syntax of properties definitions).

To supply the bindings generator with this information, bind *additional-properties* to such list when the generator is run.
