Tkinter 页面未加载
Tkinter page not loading
我的 Tkinter 程序中的一个页面没有加载。我不确定为什么
我的 InsertOperation class 中有一个 get() 方法，它用于从前一个 class 中检索所选单选按钮的值并执行适当的部分我的代码。然而，这个 get() 方法似乎并没有这样做。有替代方案吗？

没有错误信息
所有 类 都是在开始时创建的，因此 __init__ 中的所有代码甚至在您看到 window 和 get() 之前就开始执行 select元素.
您必须在函数中使用 get()，当您更改 pages/frames 时将执行该函数。
您可以在所有页面中添加功能即。 update_page（不要使用名称 update() 因为 tkinter 已经使用了这个名称）并在 show frame 中执行为 my_ops.update_page()
现在您可以将 get() 移动到 update_page()
