Change color of a row of a QTableView?

[panoss]

I changed the 'QtCore.Qt.red' to 'QBrush(Qt.red)' and works!

Here is a small working example:

from PyQt4 import QtGui, QtCore
from PyQt4.QtCore import *
from PyQt4.QtGui import *
import sys

def main():
   app = QApplication(sys.argv)
   w = MyWindow()
   w.show()
   sys.exit(app.exec_())

class MyWindow(QTableView):
   def __init__(self, *args):
       QTableView.__init__(self, *args)

       model = QtGui.QStandardItemModel(0, 2)
       self.setModel(model)

       for i in range(0,6):
           newRow = model.rowCount();
           model.insertRow(newRow);

       # paint first two rows
       for i in range(0, 2):
           model.setData(model.index(i, 0), QBrush(Qt.red), QtCore.Qt.BackgroundRole)
           model.setData(model.index(i, 1), QBrush(Qt.red), QtCore.Qt.BackgroundRole)


if __name__ == "__main__":
   main()

But I do have a question:
when I comment out the line 'from PyQt4.QtCore import *', I get an error 'Qt unresolved reference' even though I have the line 'from PyQt4 import QtGui, QtCore'.
So, what is the proper way to import QtCore without having to import it twice?
