Python PyQt4到PyQt5：继承问题

我想转换成PyQt5。 我遇到了一个我不明白的问题：

from PyQt5 import QtWidgets
import logging

class QPlainTextEditLogger(logging.Handler):
    def __init__(self, parent):
        super().__init__(parent)


class MyDialog(QtWidgets.QDialog, QPlainTextEditLogger):
    def __init__(self, parent=None):
        super().__init__()    # <= Error here

if (__name__ == '__main__'):
    app = None
    if (not QtWidgets.QApplication.instance()):
        app = QtWidgets.QApplication([])
    dlg = MyDialog()
    dlg.show()
    dlg.raise_()
    if (app):
        app.exec_()

有人能帮我吗
