- 一、用qtdesigner创建两个ui文件,并通过pyuic生成.py文件
- 二、用pycharm创建一个runMain.py文件
- 总结
提示：这里可以添加本文要记录的大概内容：
有同学刚开始学习pyqt5想实现一个注册与登录功能，并且登录完成之后想要跳转界面，但是网上资源太多，详细能够跑成功的代码还要自己筛选，由于项目需要，我自己实现了一个简单的注册，登录，以及登录跳转功能，注册是简单的存放在ini文件中的，登录是从ini文件中取用户名和密码，这个简单的功能，大家来看看是怎么实现的吧，废话不说，直接上代码
提示：以下是本篇文章正文内容，下面案例可供参考
一、用qtdesigner创建两个ui文件,并通过pyuic生成.py文件首先创建一个login.ui和main.ui两个文件，通过pyuic生成.py的代码
login.ui ->login.py
