我需要帮助来创建一个新的 TKinter 窗口而不是扩展当前窗口

Question

这是我想尝试并提出的数学挑战的代码，它提出了尽可能多的问题 但它会不断扩展窗口而不是创建一个新窗口，这也不会更新 scorestr。

关于如何让它“溶解”当前画布，然后关闭并重新打开带有新问题和更新分数的更新画布的任何帮助？

另外，如果有人知道如何在其中设置一个 60 秒的计时器，那将会对我有很大帮助。

图片显示了我遇到的问题。

请注意 仅在将整数转换为字符串后参考加号部分，其他部分尚未更新，因为加号仍然不起作用。

Window Extending

Answer 1

所以，如果你想在旧窗口打开的同时添加一个新窗口，那么你必须使用 Tkinter 中的 TopLevel 窗口。 Top1 = tk.Toplevel(root) 它应该会打开一个新窗口。

但是，如果你想删除根窗口并创建一个新窗口，你必须使用 root.destroy() 关闭任何根窗口。在按钮的功能内执行此操作

root = tk.Tk()再次打开窗口。

您必须再次添加画布和其他小部件才能更新。或者你可以简单地使用while循环来获取它
