[PyQt] Error when attempting to use load UI files into Python

[Scott Lanahan]

Hi,

I'm desperately trying to use uic.loadUi to load my main window into
Python. I cannot get it to work for the main window, but it works fine for
various widgets that are in the same Qt project. When I try to load the .ui
file, I get the following error:
Traceback (most recent call last):

TypeError: __init__() takes exactly 1 argument (2 given)


Here is the code I am trying to run:

class mainWindow(QtGui.QMainWindow):
    def __init__(self,parent=None):
        QtGui.QMainWindow.__init__(self, parent)
        self.ui = uic.loadUi('mainwindow.ui', self)


if __name__ == "__main__":
    QtGui.QApplication.setStyle(QtGui.QStyleFactory.create("Cleanlooks"))

QtGui.QApplication.setPalette(QtGui.QApplication.style().standardPalette())
    app = QtGui.QApplication(sys.argv)
    myapp = mainWindow()
    myapp.show()
    sys.exit(app.exec_())

My google-fu is usually very strong, but I have been unable to determine
the root of this problem. I have worked and worked on it, but still no
luck. Please help!

Thanks,
Scott
