Question

我知道这是一个典型的pyqt4到pyqt5移植问题，但到目前为止，现有的问题并没有帮助我找到解决当前问题的方法：我可以推动吗？

以下是生成以下错误的类

AttributeError: type object 'QObject' has no attribute 'connect'

        self.feedbacks = []

        self.setFeedbackController(bcinetwork.LOCALHOST, bcinetwork.FC_PORT)

通常将操作连接到此处的方法

时会出现问题

        QtCore.QObject.connect(self.actionChangeFeedbackController, QtCore.SIGNAL("triggered()"), self.changeFeedbackController)

这让我得到了提及的错误

AttributeError: type object 'QObject' has no attribute 'connect'

我理解代码的这一部分是典型的Pyqt4问题，它在Pyqt5中不再起作用。所以我看到了针对特定小部件的新信号的许多解释，但我没有看到一般的动作的解决方案。有人能给我一个解释吗？

好吧我认为我通过以下方式实现了它：

#QtCore.QObject.connect(self.actionChangeFeedbackController, QtCore.SIGNAL("triggered()"), self.changeFeedbackController)
 self.actionChangeFeedbackController.triggered.connect(self.changeFeedbackController)

将操作连接到方法时出现pyqt5移植错误：AttributeError：type object＆＃39; QObject＆＃39;没有属性＆＃39; connect＆＃39;
