Python 为什么不是'；我的GUI不工作吗？

我只是想知道我犯了什么错误，这意味着我的GUI不能工作。它的作用是打开一个有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——显然对于客户注册来说，它会打开一个注册页面。谢谢

    root = tk.Tk()

    main()

不确定您想要实现什么，那么main方法中的这段代码呢

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，第二个按钮打开客户注册窗口，第三个按钮打开另一个登录窗口（驾驶员登录）

除了应为

tk.Text

的键入

tk.Tex

之外，更改将加载注册帐户并登录页面，但不会加载包含所有按钮的主窗口。在第一个窗口中显示的是什么而不是我想显示的是什么？您的问题中的代码当前在做什么？即，它是如何不正常工作的？您希望它做什么？此问题缺少一个问题。你不能只转储一百行代码，然后问“为什么它不能做我期望它做的事情？”首先定义你期望它做的事情，然后构建一个显示你正在经历的行为的最小示例，然后发布这个最小示例。@martineau是它当前正在做的事情，我希望它做的事情高于代码。它只是没有加载第一个窗口（有3个选项），而是加载了CustReg和loginooh，几乎就在那里：D就是现在显示的，我只需要去掉3个按钮下面的部分。我只输入你给我的，没有改变任何东西。对我来说，它只正确显示一个窗口，我发布了完整的代码
