我开发了一个python程序。以下代码是我的程序。问题是当我单击调用self.restartClicked（）方法的self.ui.Restart_Btn并单击self.ui.B11时，它会调用self.boardClicked（）方法两次（它应该只调用一次）。此外，点击self.ui.Restart_Btn第3，第4，第5，...次后，它会反复调用3,4,5 ......次，然后点击self.ui.B11
我不知道我的程序会发生什么。

答案 0 :(得分：1)
原因相对简单，你误解了连接在Qt中是如何工作的。
在每次调用某些方法时，您似乎都在将信号连接到插槽。这似乎与你（理所当然）想要的东西相冲突。
您有针对此问题的解决方法和解决方案。
使用唯一连接（type=Qt.UniqueConnection）。
将这些连接调用移至初始化阶段或至少在重新连接之前断开连接。前者是一般惯例，但您的里程可能会有所不同。
