我如何从另一个类的QLineEdit小部件访问信息？

Question

PYQT5在PYCHARM上

目前，我有一个MainWindow（mainwindow.py）类和一个DialogWindow（dialog.py）类。另外，我有一个main.py文件，它为两个类运行代码。我想将dialog.py中标签的文本设置为来自mainwindow.py，QLineEdit，inputedit的信息。我可以知道怎么做吗？感谢提供的任何帮助。谢谢！

mainwindow.py

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        self.inputedit = QtWidgets.QLineEdit(self.centralwidget)
        self.inputedit.setGeometry(QtCore.QRect(80, 80, 311, 21))
        self.inputedit.setPlaceholderText("Input company name in ALL CAPITAL LETTERS")
        self.inputedit.setObjectName("inputedit")

dialog.py

class Ui_Dialog(object):
    def setupUi(self, Dialog):
        self.label = QtWidgets.QLabel(Dialog)
        self.label.setGeometry(QtCore.QRect(30, 40, 351, 91))
        self.label.setObjectName("label")
    def retranslateUi(self, Dialog):
        self.label.setText(_translate("Dialog", "ASD"))

main.py

class MyDialog(QDialog):
    def __init__(self):
        super().__init__()
        self.ui  = Ui_Dialog()
        self.ui.setupUi(self)


class MyWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)

    def dialogbox(self):
        self.hide()
        self.myDialog = MyDialog()
        self.myDialog.show()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    w = MyWindow()
    w.show()
    sys.exit(app.exec_())

考虑到以上解决方案，该想法是访问在一个共享对话框的范围内的两个对象，在这种情况下，它是对话框。

def dialogbox(self):
    self.hide()
    self.myDialog = MyDialog()
    self.myDialog.ui.label.setText(self.ui.inputedit.text())
    self.myDialog.show()
