当我运行登录页面并单击“注册”按钮时，它不会重定向到注册页面，而是仅保留在登录页面上

root = Tk()
obj = Register(root)
root.mainloop()

我已经为按钮插入了动作，command = register但是它仍然没有重定向到注册页面。我的命令功能有任何错误吗？

最好register.py在函数中移动主块代码：

class Register:
    ...

def RegisterForm():
    win = Toplevel()
    obj = Register(win)

然后，您可以在登录页面中使用此功能：

import register
...

class Login:
    def __init__(self):
        ...
        Button(framelogin,text="Sign Up",command=self.register,bg="white",fg="orange",font=("trebuchet ms",12)).place(x=510,y=305)
        ...

    def register(self):
        register.RegisterForm()
