为什么我的GUI没有工作？

Question

我只是想知道我犯了什么错误，这意味着我的GUI无法正常工作。它的意思是打开一个带有3个按钮的窗口，当你点击这些按钮时，它会打开一个新的GUI - 显然对于Customer注册，它会打开一个注册页面。谢谢！

import tkinter as tk

class MainWindow:
    def __init__(self, master):
        self.master = master
        self.frame = tk.Frame(self.master)
        self.button1 = tk.Button(self.frame, text = "Customer login", width = 25, command = self.new_window)
        self.button1.pack()
        self.button2 = tk.Button(self.frame, text = "Customer register", width = 25, command = self.new_window2)
        self.button2.pack()
        self.button3 = tk.Button(self.frame, text = "Driver login", width = 25, command = self.new_window3)
        self.button3.pack()
        self.frame.pack()

不确定您要实现的目标，主方法中的代码如何

def main():
    root = tk.Tk()
    app = MainWindow(root)
    root.mainloop()

它似乎更接近你想要实现的目标。它打开一个窗口，第一个按钮打开登录窗口，第二个打开客户注册窗口，第三个打开另一个登录窗口（驱动程序登录）
