AttributeError: объект 'module' не имеет атрибута 'QMainWindowWindowWidget'

Question

, поэтому я создаю приложение Windows с Python и PyQt4. Я использую Python 2.7.6. Пользовательский интерфейс файла преобразования I с помощью pyuic4 form_window.ui -o form_window.py

from PyQt4 import QtCore, QtGui 
import sys 

try: 
    _fromUtf8 = QtCore.QString.fromUtf8 
except AttributeError: 
    def _fromUtf8(s): 
     return s 

try: 
    _encoding = QtGui.QApplication.UnicodeUTF8 
    def _translate(context, text, disambig): 
     return QtGui.QApplication.translate(context, text, disambig, _encoding) 
except AttributeError: 
    def _translate(context, text, disambig): 
     return QtGui.QApplication.translate(context, text, disambig) 

class Ui_MainWindow(QtGui.QMainWindowWidget): 
    def __init__(self): 
     QtGui.QMainWindow.__init__(self) 
     self.setupUi(self) 

    def setupUi(self, MainWindow): 
     MainWindow.setObjectName(_fromUtf8("MainWindow")) 
     MainWindow.resize(623, 359) 
     self.centralWidget = QtGui.QWidget(MainWindow) 
     self.centralWidget.setObjectName(_fromUtf8("centralWidget")) 
     self.textEdit = QtGui.QTextEdit(self.centralWidget) 
     self.textEdit.setGeometry(QtCore.QRect(230, 40, 371, 281)) 
     self.textEdit.setObjectName(_fromUtf8("textEdit")) 
     self.lineEdit = QtGui.QLineEdit(self.centralWidget) 
     self.lineEdit.setGeometry(QtCore.QRect(10, 40, 191, 23)) 
     self.lineEdit.setObjectName(_fromUtf8("lineEdit")) 
     self.lineEdit_2 = QtGui.QLineEdit(self.centralWidget) 
     self.lineEdit_2.setGeometry(QtCore.QRect(10, 80, 191, 23)) 
     self.lineEdit_2.setObjectName(_fromUtf8("lineEdit_2")) 
     self.lineEdit_3 = QtGui.QLineEdit(self.centralWidget) 
     self.lineEdit_3.setGeometry(QtCore.QRect(10, 120, 191, 23)) 
     self.lineEdit_3.setObjectName(_fromUtf8("lineEdit_3")) 
     self.label = QtGui.QLabel(self.centralWidget) 
     self.label.setGeometry(QtCore.QRect(240, 20, 59, 15)) 
     self.label.setObjectName(_fromUtf8("label")) 
     self.label_2 = QtGui.QLabel(self.centralWidget) 
     self.label_2.setGeometry(QtCore.QRect(10, 20, 59, 15)) 
     self.label_2.setObjectName(_fromUtf8("label_2")) 
     self.label_3 = QtGui.QLabel(self.centralWidget) 
     self.label_3.setGeometry(QtCore.QRect(10, 60, 59, 21)) 
     self.label_3.setObjectName(_fromUtf8("label_3")) 
     self.label_4 = QtGui.QLabel(self.centralWidget) 
     self.label_4.setGeometry(QtCore.QRect(10, 100, 111, 21)) 
     self.label_4.setObjectName(_fromUtf8("label_4")) 
     self.zapisz_btm = QtGui.QPushButton(self.centralWidget) 
     self.zapisz_btm.setGeometry(QtCore.QRect(20, 270, 80, 23)) 
     self.zapisz_btm.setObjectName(_fromUtf8("zapisz_btm")) 
     MainWindow.setCentralWidget(self.centralWidget) 
     self.menuBar = QtGui.QMenuBar(MainWindow) 
     self.menuBar.setGeometry(QtCore.QRect(0, 0, 623, 20)) 
     self.menuBar.setObjectName(_fromUtf8("menuBar")) 
     self.menuForm = QtGui.QMenu(self.menuBar) 
     self.menuForm.setObjectName(_fromUtf8("menuForm")) 
     MainWindow.setMenuBar(self.menuBar) 
     self.mainToolBar = QtGui.QToolBar(MainWindow) 
     self.mainToolBar.setObjectName(_fromUtf8("mainToolBar")) 
     MainWindow.addToolBar(QtCore.Qt.TopToolBarArea, self.mainToolBar) 
     self.statusBar = QtGui.QStatusBar(MainWindow) 
     self.statusBar.setObjectName(_fromUtf8("statusBar")) 
     MainWindow.setStatusBar(self.statusBar) 
     self.menuBar.addAction(self.menuForm.menuAction()) 

     self.retranslateUi(MainWindow) 
     QtCore.QMetaObject.connectSlotsByName(MainWindow) 

    def retranslateUi(self, MainWindow): 
     MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow", None)) 
     self.label.setText(_translate("MainWindow", "Opis", None)) 
     self.label_2.setText(_translate("MainWindow", "Adres", None)) 
     self.label_3.setText(_translate("MainWindow", "Tytul", None)) 
     self.label_4.setText(_translate("MainWindow", "Slowa kluczowe", None)) 
     self.zapisz_btm.setText(_translate("MainWindow", "Zapisz", None)) 
     self.menuForm.setTitle(_translate("MainWindow", "Form", None)) 

if __name__ == '__main__': 
    app = QtGui.QApplication(sys.argv) 
    ex = Ui_MainWindow() 
    ex.show() 
    sys.exit(app.exec_()) 

Когда я запускаю мой код у меня есть ошибка

Traceback (most recent call last): 
    File "/home/develop/PycharmProjects/untitled/form_window.py", line 18, in <module> 
    class Ui_MainWindow(QtGui.QMainWindowWidget): 
AttributeError: 'module' object has no attribute 'QMainWindowWidget' 

Я понятия не имею, что я делаю неправильно

Answer 1

Не знаю class QMainWindowWidget в api: http://pyqt.sourceforge.net/Docs/PyQt4/qtgui.html

Вы действительно не намереваетесь унаследовать своего от QMainWindow?
