Hi, I want to write an interface with glib-object. The situation is a parent object implements the interface, but the subclass should overwrite the function pointers in the interface. The parent class contains the following code in the function ags_recall_get_type: ... static const GInterfaceInfo ags_connectable_interface_info = { (GInterfaceInitFunc) ags_recall_connectable_interface_init, NULL, /* interface_finalize */ NULL, /* interface_data */ }; ... g_type_add_interface_static(ags_type_recall, AGS_TYPE_CONNECTABLE, &ags_connectable_interface_info); ... AgsRecall has subclasses which should overwrite the functions, but I don't know what's the proper way in the subclass to do so. How do I tell GInterface to call a function of the subclass to overwrite? One more, is it correct to make an object cast on the interface e.g. (where AgsConnectable is an interface which is implemented by AgsRecall): void ags_recall_connect(AgsConnectable connectable) { AGS_RECALL(connectable); ... } _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
