    Question A Widget is not updated

    I am having a hard time to find why the widget is not updated in my project.
    Because the project is too big to upload in this post, I made a simplified code.



    Qt Code: 
    1. from PyQt5 import QtCore, QtGui, QtWidgets
    2. class Ui_Form(object):
    3.     def setupUi(self, Form):
    4.         Form.setObjectName("Form")
    5.         Form.resize(191, 223)
    6.         self.verticalLayoutWidget = QtWidgets.QWidget(Form)
    7.         self.verticalLayoutWidget.setGeometry(QtCore.QRect(0, 170, 191, 21))
    8.         self.verticalLayoutWidget.setObjectName("verticalLayoutWidget")
    9.         self.verticalLayout = QtWidgets.QVBoxLayout(self.verticalLayoutWidget)
    10.         self.verticalLayout.setContentsMargins(55, 0, 55, 0)
    11.         self.verticalLayout.setObjectName("verticalLayout")
    12.         self.saveButton = QtWidgets.QPushButton(self.verticalLayoutWidget)
    13.         self.saveButton.setStyleSheet("background-color: rgb(200, 200, 200)")
    14.         self.saveButton.setFlat(False)
    15.         self.saveButton.setObjectName("saveButton")
    16.         self.verticalLayout.addWidget(self.saveButton)
    17.         self.layoutWidget = QtWidgets.QWidget(Form)
    18.         self.layoutWidget.setGeometry(QtCore.QRect(0, 20, 191, 22))
    19.         self.layoutWidget.setObjectName("layoutWidget")
    20.         self.threadcountLayout = QtWidgets.QHBoxLayout(self.layoutWidget)
    21.         self.threadcountLayout.setContentsMargins(5, 0, 0, 0)
    22.         self.threadcountLayout.setObjectName("threadcountLayout")
    23.         self.label = QtWidgets.QLabel(self.layoutWidget)
    24.         sizePolicy = QtWidgets.QSizePolicy(QtWidgets.QSizePolicy.Preferred, QtWidgets.QSizePolicy.Preferred)
    25.         sizePolicy.setHorizontalStretch(0)
    26.         sizePolicy.setVerticalStretch(0)
    27.         sizePolicy.setHeightForWidth(self.label.sizePolicy().hasHeightForWidth())
    28.         self.label.setSizePolicy(sizePolicy)
    29.         self.label.setObjectName("label")
    30.         self.threadcountLayout.addWidget(self.label)
    31.         self.threadcountLineEdit = QtWidgets.QLineEdit(self.layoutWidget)
    32.         sizePolicy = QtWidgets.QSizePolicy(QtWidgets.QSizePolicy.Fixed, QtWidgets.QSizePolicy.Fixed)
    33.         sizePolicy.setHorizontalStretch(0)
    34.         sizePolicy.setVerticalStretch(0)
    35.         sizePolicy.setHeightForWidth(self.threadcountLineEdit.sizePolicy().hasHeightForWidth())
    36.         self.threadcountLineEdit.setSizePolicy(sizePolicy)
    37.         self.threadcountLineEdit.setMinimumSize(QtCore.QSize(25, 20))
    38.         self.threadcountLineEdit.setMaximumSize(QtCore.QSize(1, 20))
    39.         self.threadcountLineEdit.setMaxLength(3)
    40.         self.threadcountLineEdit.setObjectName("threadcountLineEdit")
    41.         self.threadcountLayout.addWidget(self.threadcountLineEdit)
    42.         self.label_2 = QtWidgets.QLabel(self.layoutWidget)
    43.         sizePolicy = QtWidgets.QSizePolicy(QtWidgets.QSizePolicy.Preferred, QtWidgets.QSizePolicy.Preferred)
    44.         sizePolicy.setHorizontalStretch(0)
    45.         sizePolicy.setVerticalStretch(0)
    46.         sizePolicy.setHeightForWidth(self.label_2.sizePolicy().hasHeightForWidth())
    47.         self.label_2.setSizePolicy(sizePolicy)
    48.         self.label_2.setObjectName("label_2")
    49.         self.threadcountLayout.addWidget(self.label_2)
    50.         self.retranslateUi(Form)
    51.         QtCore.QMetaObject.connectSlotsByName(Form)
    52.  
    53.     def retranslateUi(self, Form):
    54.         _translate = QtCore.QCoreApplication.translate
    55.         Form.setWindowTitle(_translate("Form", "Form"))
    56.         self.saveButton.setText(_translate("Form", "save"))
    57.         self.label.setText(_translate("Form", "HTTP thread count"))
    58.         self.threadcountLineEdit.setText(_translate("Form", "0"))
    59.         self.label_2.setText(_translate("Form", "s"))
    60.  
    61.  
    62. class Ui_MainWindow(object):
    63.     def setupUi(self, MainWindow):
    64.         MainWindow.setObjectName("MainWindow")
    65.         MainWindow.resize(331, 351)
    66.         sizePolicy = QtWidgets.QSizePolicy(QtWidgets.QSizePolicy.Fixed, QtWidgets.QSizePolicy.Fixed)
    67.         sizePolicy.setHorizontalStretch(0)
    68.         sizePolicy.setVerticalStretch(0)
    69.         sizePolicy.setHeightForWidth(MainWindow.sizePolicy().hasHeightForWidth())
    70.         MainWindow.setSizePolicy(sizePolicy)
    71.         MainWindow.setMinimumSize(QtCore.QSize(331, 351))
    72.         MainWindow.setMaximumSize(QtCore.QSize(331, 351))
    73.         MainWindow.setStyleSheet("background-color:rgb(250, 255, 151)")
    74.  
    75.  
    76. if __name__ == "__main__":
    77.     import sys
    78.     app = QtWidgets.QApplication(sys.argv)
    79.     MainWindow = QtWidgets.QMainWindow()
    80.     ui = Ui_MainWindow()
    81.     ui.setupUi(MainWindow)
    82.     MainWindow.show()
    83.     ui = Ui_Form()
    84.     ui.setupUi(MainWindow)
    85.     sys.exit(app.exec_())
    To copy to clipboard, switch view to plain text mode 

    setupUi function of Ui_MainWindow is properly applied, but the one of Ui_Form is not applied.
    How can I solve this problem?

    Try "ui.setupUi( Form )".
