Tkinter - 更新 OptionMenu 中的数据

Question

I have created an OptionMenu to display a list of usernames.

For example:

self.accounts_option_menu = ttk.OptionMenu(self, self.menu, user_name_list[0],
                                           *user_name_list, command=self.some_func)

At some point I want to update/change this list to be longer or shorter (removing or adding from the list). My question is: How can I achive that?

Answer 1

如果你把self.accounts_option_menu = ttk.OptionMenu(self, self.menu, user_name_list[0], *user_name_list, command=self.some_func)放在它自己的任何类的方法中，那么你应该能够做到通过调用该方法再次使用不同的列表。
