标题几乎总结了这个问题。我有一个我已经编写好的GUI，我试图修改我的错误处理以更好地利用PyQt的信号和插槽。但是，我遇到了一些问题。我正在测试一个错误处理语句，如果用户点击某个特定的按钮，会出现一个对话框，告诉他们他们还没有输入正确的信息。该对话框由信号和插槽控制，并在应有时出现。但是，如果我关闭对话框，然后再次单击该按钮，对话框将弹出两次。这会发生叠加。也就是说，如果我第三次单击该按钮，则会出现三次对话框，依此类推。我不知道还有什么要做。我试图检查以确保所有QThreads结束。我甚至去使用QThread.terminate（），你永远不应该这样做，我仍然以相同的结果结束。任何想法是什么导致这一点？代码snipet在下面。PyQt在每次点击后创建添加对话框
