Thank you Phil

After some attempts i found that this works:

db.driver().notification['QString', 'QSqlDriver::NotificationSource', 
'QVariant'].connect(notify_handle)

and this too:

db.driver().notification[str, 'QSqlDriver::NotificationSource', 
'QVariant'].connect(notify_handle)

maybe this is usefull for other people troubling with similar problems
