'Ui_MainWindow' object has no attribute



  • 'Ui_MainWindow' object has no attribute 'lbl_Question_No_denary' is the error I keep getting I import UI code for a GUI made in QT Designer. The GUI has 3 tabs. the first tabs widgets are recognised, but the second is not?
    the code is below:
    class MainWindow_EXEC():

    def init(self):
    app = QtWidgets.QApplication(sys.argv)

    MainWindow = QtWidgets.QMainWindow()
    self.ui = Ui_MainWindow()
    self.ui.setupUi(MainWindow)
    
    # Binary Game instantiation
    self.ui.lbl_DenarytoBinary_Question_No.setText(str(1))
    self.ui.lbl_BinarytoDenary_currentScore.setText(str(0))
    self.ui.progressBar_BinarytoDenary.setValue(0)
    self.ui.lbl_BinarytoDenary_result.setText("")
    self.ui.lbl_BinarytoDenary_result_2.setText("")
    
    self.ui.spinBox_BinarytoDenary.setValue(0)
    self.createRandomBinaryNumber()
    self.ui.btn_BinarytoDenary_Answer.clicked.connect(self.getAnswerBinary)
    
    # Denary Game instantiation
    

    self.ui.lbl_Question_No_denary.setText(str(1))

    self.ui.lbl_random_number_denary.setText(str(00))
    self.ui.self.spinBox_16_denary.setValue(0)
    self.ui.self.spinBox_8_denary.setValue(0)
    self.ui.self.spinBox_4_denary.setValue(0)
    self.ui.self.spinBox_2_denary.setValue(0)
    self.ui.self.spinBox_1_denary.setValue(0)
    self.progressBar_denary.setValue(0)

    self.createRandomDenaryNumber()
    self.btn_Answer_denary.clicked.connect(self.getAnswerDenary)

    MainWindow.show()
    sys.exit(app.exec_())

    @Steve-Horton said in 'Ui_MainWindow' object has no attribute:

    lbl_Question_No_denary

    Is the name really correct?



  • yes, its. I have checked. It does not recognise any of the widgets from the second tab.

    Hi
    How do you import it ?
    as far as i understand one has to run pyuic5 on the ui file to generate ?
