我知道 TKinter 在執行緒中運行時不會保存。沒關系，我創建了一個程式，我在執行緒中啟動 tkinter 模塊。在我將主題設定添加到代碼之前，它對我來說很好。

如果我在此版本或其他版本中運行此代碼，則會收到錯誤代碼：主執行緒不在主回圈中。我嘗試在主回圈中配置一次主題并在函式中使用全域匯入它，我嘗試在函式中使用相同或不同的變數名對其進行配置。
我希望我的代碼不是那么難讀。我希望你能幫我解決這個問題。謝謝！
uj5u.com熱心網友回復：
我通過撰寫測驗代碼找到了解決方案，因此更容易閱讀。我不知道為什么代碼必須那么復雜，但我想分享我最近幾天的經驗。以下代碼對用戶具有幾乎相同的功能。由于樣式線，第二個代碼不起作用。由于我的代碼中有一個名為“screenmanager”的額外函式，第三個再次起作用

最后但并非最不重要的一點是，我不確定它為什么會這樣作業，但我認為當我直接在 threadstarter 呼叫新螢屏時，我會為新螢屏提供一些變數，這些變數將在錯誤訊息主執行緒中結束，而不是在第二個主回圈中代碼。最終有人知道第二個代碼中的真正錯誤是什么。
