Description

The BonoboArg code, and macros are designed to make the use of CORBA_Any's slightly simpler by providing a glib like binding for them. The bonobo-arg code also provides mappings between Gtk Args and CORBA_anys.

A typical use of the BonoboArg macros would be in

Example 1. Property bag implementation

static void
get_prop (BonoboPropertyBag *bag,
	  BonoboArg         *arg,
	  guint              arg_id,
	  CORBA_Environment *ev,
	  gpointer           user_data)
{
	GtkObject *clock = user_data;

	switch (arg_id) {

	case PROP_RUNNING: {
		BONOBO_ARG_SET_BOOLEAN (arg, is_it_running);
		break;
	}

	default:
		bonobo_exception_set (ev, ex_Bonobo_PropertyBag_NotFound);
		break;
	}
}
