Hi, look up the Q_DECLARE_INTERFACE macro definition. The docs describe this as "Use the Q_DECLARE_INTERFACE() macro to tell Qt's meta-object system about the interface." -- Regards Samuel _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
