我已经解决了一个多小时，但无法解决此问题。 我的错误是下面显示的链接。 [This is my error 我有两个班，我的主班和虚拟键盘班。 如果单击输入小部件，则必须弹出虚拟键盘。 我使用.bind，这是我的主类 init 中的代码。
def __init__(self, master, *args, **kwargs):
tk.Frame.__init__(self, master, *args, **kwargs)
self.master = master
master.title("Thesis")
self.login_button = Button(master, text = "Login",command = self.login, bg= "white")
self.login_button.pack()
self.register_button = Button(master, text="Register", command=self.register)

我认为我的问题是继承或处理程序，这是我第一次进行继承并调用另一个类。我的主类没有任何问题，我的数据库和注册功能运行正常。但是，当我将虚拟键盘添加为另一个类时，出现了此错误。 希望你们能帮助我。 非常感谢！
