在附加的執行緒tkinter巧妙示例中命名進度條

我是 python 新手，正在嘗試處理 GUI 應用程式中的執行緒部分我下載了以下示例，該示例將進度框命名為“tk”，這似乎與 self 和 parent 相關，所以我想我需要找到一個使測驗字串“progress”進入這些名稱出現的地方之一的方法。作為一個 python 新手，考慮到整個示例的構建方式非常緊湊，我還不夠聰明，無法知道正確和最緊湊的方式來做到這一點。

uj5u.com熱心網友回復：

要更改標題欄...只需使用title根小部件上的方法。在腳本的基礎上。

ROOT = tk.Tk()
ROOT.title("Anything you want it to be.")
APP = AppGUI(ROOT)
ROOT.mainloop()
