这是一个对话框gui 框里只有一个按钮pushButton  现在想实现的就是  鼠标点击这个pushButton 会弹出一个提示
可是当鼠标点击这个pushButton 时，会出错误提示：
e:\pytest>python mytest.py
Traceback (most recent call last):
  File "mytest.py", line 29, in ps_bt
    reply = QMessageBox.information(Dialog,  'Message',"Are you sure to quit?",  QMessageBox.Yes|QMessageBox.No,QMessageBox.Yes)
TypeError: information(QWidget, str, str, buttons: Union[QMessageBox.StandardButtons, QMessageBox.StandardButton] = QMessageBox.Ok, defaultButton: QMessageBox.StandardButton = QMessageBox.NoButton): argument 1 has unexpected type 'bool'

e:\pytest>

搞定：
reply = QMessageBox.information(self.pushButton,  "消息","确认吗",  QMessageBox.Yes|QMessageBox.No,QMessageBox.Yes)

源错误代码：
reply = QMessageBox.information(Dialog,  'Message',"Are you sure to quit?",  QMessageBox.Yes|QMessageBox.No,QMessageBox.Yes)
