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;
	}
}

bonobo_arg_new ()

BonoboArg*  bonobo_arg_new                  (BonoboArgType t);

Create a new BonoboArg with the specified type the value of the BonoboArg is initially empty.

t : the BonoboArgType eg. TC_long
Returns : 

bonobo_arg_release ()

void        bonobo_arg_release              (BonoboArg *arg);

This frees the memory associated with arg

arg : the bonobo arg.

bonobo_arg_copy ()

BonoboArg*  bonobo_arg_copy                 (const BonoboArg *arg);

This function duplicates a by a deep copy

arg : the bonobo arg
Returns :a copy of arg

bonobo_arg_is_equal ()

gboolean    bonobo_arg_is_equal             (BonoboArg *a,
                                             BonoboArg *b,
                                             CORBA_Environment *opt_ev);

Compares two BonoboArgs for equivalence; will return TRUE if equivalent for all simple cases. For Object references CORBA sometimes denies 2 object references are equivalent even if they are [ this is a feature_not_bug ].

This function is commutative.

a : a bonobo arg
b : another bonobo arg
opt_ev : optional exception environment or NULL.
Returns : TRUE if a == b

bonobo_arg_type_to_gtk ()

GtkType     bonobo_arg_type_to_gtk          (BonoboArgType id);

This maps a BonoboArgType to a GtkType

id : the BonoboArgType
Returns : the mapped type or 0 on failure

bonobo_arg_type_from_gtk ()

BonoboArgType bonobo_arg_type_from_gtk      (GtkType t);

This maps a GtkType to a BonoboArgType

t : 
Returns : the mapped type or NULL on failure.

bonobo_arg_to_gtk ()

void        bonobo_arg_to_gtk               (GtkArg *a,
                                             const BonoboArg *arg);

Maps a BonoboArg to a GtkArg; a must point to a blank GtkArg.

a : pointer to a blank GtkArk
arg : the BonoboArg to copy

bonobo_arg_from_gtk ()

void        bonobo_arg_from_gtk             (BonoboArg *a,
                                             const GtkArg *arg);

This maps a GtkArg arg to a BonoboArg a; a must point to a freshly allocated BonoboArg eg. such as returned by bonobo_arg_new

a : pointer to blank BonoboArg
arg : GtkArg to copy

bonobo_arg_type_is_equal ()

gboolean    bonobo_arg_type_is_equal        (BonoboArgType a,
                                             BonoboArgType b,

This compares two BonoboArgType's in a and b. The opt_ev is an optional CORBA_Environment for exceptions, or NULL. This function is commutative.

a : a type code
b : a type code
opt_ev : optional exception environment or NULL.
