not quite. the correct way to control the lifecycle of *any* GtkObject
(note, _g_t_k_object, *not* _g_object) is:

o = g_object_new (GTK_TYPE_*, NULL);
gtk_object_ref (o);
gtk_object_sink (o);

/* do stuff with object, e.g. add/remove to/from containers */

gtk_object_destroy (o);
gtk_object_unref (o);
