单击按钮时未显示 Tkinter 框架

Question

我正在尝试在 tkinter 中开发一个学校应用程序。我正在为应用程序中的每个选项卡创建一个框架。我在代码中包含了我的选项卡作为页面。我为每个选项卡创建了 UI。单独运行时效果很好。

我试图通过堆叠框架来组合它。

我没有错误，但应用程序中与“主页”对应的 tkinter 框架未加载。

感谢任何帮助。

    def __init__(self,*args, **kwargs):

        super().__init__(*args, **kwargs)

        main_frame = tk.Frame(self,width=200,height=50,highlightbackground="black",highlightthickness=1)
        main_frame.pack(side='top', fill='both', expand='True')

        main_frame.grid_rowconfigure(0, weight=1)
