[PyQt] Is it possible to subclass QSqlDatabase?

[Mattia Borsalino]

Hi,

I'm trying to subclass QSqlDatabase, which appears to not be allowed.
The following code crashes at the first line of the main code
(addDatabase). What am I missing?

Thanks in advance,

Mattia

#!/usr/bin/python
# -*- coding: latin-1 -*-
import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.QtSql import *

class MyDatabase(QSqlDatabase):
    """
    subclasses QSqlDatabase
    """
    def __init__(self, parent=None):
        super(MyDatabase, self).__init__(parent)

if __name__ == '__main__':
    db = MyDatabase().addDatabase("QMYSQL")
    db.setHostName('localhost')
    db.setDatabaseName('mydatabase')
    db.open('root', 'mypassword')
