標題幾乎總結了這個問題。我有一個我已經編寫好的GUI，我試圖修改我的錯誤處理以更好地利用PyQt的信號和插槽。但是，我遇到了一些問題。我正在測試一個錯誤處理語句，如果用戶點擊某個特定的按鈕，會出現一個對話框，告訴他們他們還沒有輸入正確的信息。該對話框由信號和插槽控制，並在應有時出現。但是，如果我關閉對話框，然後再次單擊該按鈕，對話框將彈出兩次。這會發生疊加。也就是說，如果我第三次單擊該按鈕，則會出現三次對話框，依此類推。我不知道還有什麼要做。我試圖檢查以確保所有QThreads結束。我甚至去使用QThread.terminate（），你永遠不應該這樣做，我仍然以相同的結果結束。任何想法是什麼導致這一點？代碼snipet在下面。PyQt在每次點擊後創建添加對話框
