我遇到了一个问题，我需要能够使用按钮将条目提交到sqlite数据库，还可以使用相同的按钮更改框架。这是一个学校项目，我在编程方面是一个业余爱好者。这是我到目前为止的代码，它返回错误AttributeError: '_tkinter.tkapp' object has no attribute 'confirm_button'。
我尝试创建一个名为confirm_button的新函数，但它无效。需要帮助的位在第1页的类中，它是确认按钮。

答案 0 :(得分：1)
这是（希望）修复后的代码版本。你需要继续开发它（因为我对SQL知之甚少），但应该完成GUI的工作。
注意：只是一点点，我添加了代码以允许DPI识别，因此，在特定设置上，这将使文本更清晰。
