如何調用窗口小部件類框架並將其打包到主窗口應用程序類中？ tkinter

Question

我在創建數據庫GUI時遇到了麻煩。 我創建的小部件如類*（tk.Frame）： 後來我嘗試和創造，並在「MainApplication（tk.Frame）收拾他們：類 然而，小部件不會出現 我。約根，「自我」是我傳遞到MainApplication，然後從那裏進入窗口小部件類有點困惑。 如何獲得小部件顯示出來？

看起來您正在創建一個名爲actionButtonContainer的框架，並在其中放置按鈕。但是，您使用包或網格使這個框架可見，所以它和它的所有孩子都將隱形。

由於ActionButtons已經是一個框架，我不明白你爲什麼需要這個容器框架。您可能只想製作self的按鈕子項。
