В Qt можно распечатать список методов, поддерживаемых объектом, причем сделать это "на лету", во время выполнения программы.
Пример кода:
int i,n = qApp->staticMetaObject.methodCount();
for(i=0;i<n;i++)
qDebug() << "App method" << i << qApp->staticMetaObject.method(i).methodSignature();
Данный код выводит список методов объекта приложения. Вывод будет примерно таким:
01:34:23 [DBG] App method 0 "destroyed(QObject*)"
01:34:23 [DBG] App method 1 "destroyed()"
01:34:23 [DBG] App method 2 "objectNameChanged(QString)"
01:34:23 [DBG] App method 3 "deleteLater()"
01:34:23 [DBG] App method 4 "_q_reregisterTimers(void*)"
01:34:23 [DBG] App method 5 "aboutToQuit()"
01:34:23 [DBG] App method 6 "organizationNameChanged()"
01:34:23 [DBG] App method 7 "organizationDomainChanged()"
01:34:23 [DBG] App method 8 "applicationNameChanged()"
01:34:23 [DBG] App method 9 "applicationVersionChanged()"
