链接两个QMainWindow pyqt5

Question

人们正在尝试编写一个程序，该程序从一个窗口获取详细信息并将其导入到另一个窗口的配置文件中。我希望它在同一应用程序上...我所看到的只是qdialog类，我不想使用它

am从第一个窗口获取数据，然后将其导入第二个窗口

这是我的第一个代码

def loader(self):       
    widget = QWidget()
    self.setCentralWidget(widget)
    #layouts
    self.layout = QFormLayout()
    self.descriLayout = QVBoxLayout()
    self.buttonLayout = QHBoxLayout()

    #QFormLayout dealz
    self.name = QLabel('name')
    items = ['male' , 'female' , 'none']
    self.sexchooser = QComboBox()
    for item in items:
        self.sexchooser.addItem(item)

    self.age = QLabel('age')
    self.optcourse = QLabel('Opted Course')
    self.nameEdit = QLineEdit()
    #self.nameEdit.editingFinished()
    self.nameEdit.setPlaceholderText('enter name here')
    self.coursEdit = QLineEdit()
    self.coursEdit.setPlaceholderText('Mt || Ph || St')
    self.sexLabel = QLabel('sex')
    #age selector
    self.ageSelector = QComboBox()
    for x in range(18 , 40):
        self.ageSelector.addItem(str(x))
    self.descriptor = QPlainTextEdit()

    self.descriptor.setPlaceholderText('describe yourself here')
    self.descriptor.setUndoRedoEnabled(True)
    self.layout.addRow(self.name , self.nameEdit)
    self.layout.addRow(self.optcourse , self.coursEdit)
    self.layout.addRow(QLabel('sex') , self.sexchooser)
    self.layout.addRow(QLabel('Age') , self.ageSelector)

    #buttons dealz
    self.SubmitButton = QPushButton('&Submit')
    self.SubmitButton.clicked.connect(self.detailer)
    self.cancelButton = QPushButton("Can&cel")
    self.cancelButton.clicked.connect(self.close)
    self.buttonLayout.addWidget(self.SubmitButton)
    self.buttonLayout.addWidget(self.cancelButton)


    self.descriLayout.addLayout(self.layout)
    self.descriLayout.addWidget(self.descriptor)
    self.descriLayout.addLayout(self.buttonLayout)

    self.show()
    widget.setLayout(self.descriLayout)
    self.setMinimumSize(300 , 350)
    self.setMaximumSize(300 , 350)
    self.setWindowTitle('DETAILS')
def detailer(self):
    #the second window called here
