Here is the error message:

Pylint raised this on something like this in Python code:

...
from PyQt4 import QtGui, QtCore
from PyQt4.QtCore import Qt

class GenericWidget(QtGui.QWidget):
    def __init__(self, parent=None, title = '', attributes=Qt.Widget):
...
or
...
from PyQt4 import QtGui, QtCore
from PyQt4.QtCore import Qt

class GenericWindow(QtGui.QMainWindow):
    def __init__(self, parent=None, title='', attributes=Qt.Window):
...

Reason of this error is "attributes=Qt.Widget" and 
"attributes=Qt.Window" expressions in given source code, which is 
absolutely regular!?
Where is the problem?

Regards,
Stojan
