[PyKDE] PyQt4: setPaletteBackgroundColor

[Patrick Stinson]

If I change one of the to a QWidget (or QFrame) it doesn't work. Maybe we
are (or I am) missing a fundamental aspect to this 'role' concept.

        self.w2 = QFrame(self)
        self.w2.setFixedSize(100, 200)
        self.w2.setFrameStyle(QFrame.WinPanel)
