我的問題是運行一個執行緒，以便我的 GUI 不會凍結，這與window.perform_long_operation. 但是當我希望在運行執行緒時顯示一個彈出視窗然后等待來自彈出視窗的用戶輸入以繼續該功能時，就會出現問題。我正在粘貼我完整 GUI 代碼的一小部分。

如果我在頂級 GUI 的主“while”回圈中運行該函式，則可以克服該解決方案，但我希望它在單擊單選按鈕后打開的子 GUI 中運行。
為簡單起見，我僅在出現問題時提供了最少的 GUI 代碼。還有更多單選按鈕可以打開執行其他功能的子 GUI。只有“New WO”單選按鈕的功能需要在腳本結束前彈出。我再次用 google_search() 函式替換了 long 函式以簡化一切。希望這將允許其他人更快地閱讀和理解代碼。
uj5u.com熱心網友回復：
也許您可以將一個執行緒中的代碼拆分到不同的執行緒。
