PyQt4 trouble creating a simple GUI application

Question

so I\'m creating a simple windows application with Python and PyQt4. I\'ve designed my UI the way I want it in QtCreator and I\'ve created the necessary .py file from the .ui fi

Answer 1

You need to inherit from QMainWindow, not QWidget. setCentralWidget is a method of QMainWindow.

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

from ui_mainwindow import Ui_MainWindow

class Window(QMainWindow, Ui_MainWindow):
    def __init__(self, parent = None):

        QMainWindow.__init__(self, parent)
        # or better
        # super(Window, self).__init__(parent)

        self.setupUi(self)
