@
from PyQt4 import QtSql
import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.QtSql import *
import PyQt4

app = QApplication(sys.argv)
w = QTextBrowser()

DB type, host, user, password...

db = QSqlDatabase.addDatabase("qsqlmysql4");
db.setHostName("localhost")
db.setDatabaseName("test")
db.setUserName("root")
db.setPassword("")
