我想在单击按钮后显示QMessage.information框。我试图实现它但它似乎没有工作。这是我的代码和堆栈跟踪的副本。我做错了什么，在点击按钮后显示消息框的正确方法是什么。

Stack Trace

 canonical_message_box = QMessageBox.information(w, "Message",'Canonical Address Data Generated')
TypeError: QMessageBox.information(QWidget, str, str, QMessageBox.StandardButtons buttons=QMessageBox.Ok, QMessageBox.StandardButton defaultButton=QMessageBox.NoButton): argument 1 has unexpected type 'PyQt5.QtCore.pyqtWrapperType'

答案 0 :(得分：1)

问题是您正在创建一个空窗口小部件（w = QWidget），然后将其指定为QMessageBox对话框的父窗口。这需要是您的MainWindow类的实例。像这样：

self.canonicalAddressesButton.clicked.connect(lambda: self.select_canonical_data(MainWindow))
# The lambda is necessary in this circumstance to supply the MainWindow instance to your method

def select_cannonical_data(self):
    os.system('CanonicalAddressesParser.py')
    canonical_message_box = QMessageBox.information(w, "Message",'Canonical Address Data Generated')
    # Your indention is wrong on the above line in your code

此代码将为您打开对话框，但这实际上并不是设置此对话框的理想方式。您似乎在使用此特定代码时遇到了很多麻烦。我已经看到了几个关于这段完全相同代码的问题。我建议您花一些时间学习一些PyQt5教程，以便更多地了解如何正确使用它，并在此处提出这么多问题之前再研究一下。通过极少的研究，您可以很容易地找到您提出的大部分内容。
