PYQT4：关键消息框
PYQT4: Critical Message Box
好的，不确定我在这里遗漏了什么。我为工作创建了一个 GUI 应用程序，其中包含一个关闭按钮。如果用户使用自定义 window 关闭按钮，我能够执行 closeEvent 函数。但是，当他们单击 GUI 上的关闭按钮时，我无法产生相同的效果。下面是我的代码、错误和展示我的问题的 GUI 图片。在此先感谢您的帮助。

您的代码生成错误，因为 QMessageBox.critical 需要传递 QObject 对象而 Ui_MainWindow 不需要。

此外，您希望按下按钮默认关闭和您的新关闭按钮具有相同的行为，您必须将发出新按钮的信号与关闭功能连接起来，因为关闭功能调用 closeEvent.
