[Python知识库]用Python PyQt5制作校园订餐系统界面

用python pyqt5制作校园订餐系统界面

前言

??最近扒拉了一下之前的代码，发现了大一时参加软件设计大赛做的一个校园订餐系统。由于时间有限，技术也不怎么样，只实现了登录、注册、主界面，支付功能也是直接打开一个二维码扫一扫，但那时作为初学者，还是比较骄傲的。
??
??这是登录界面：
??登录时，账号密码取自数据库（MySQL），有最基本的数据判断功能。

??注册界面：
??注册后账号密码存放在数据库，也有基本的数据判断。
??主界面：
??点击左侧导航栏可以切换界面，左下角购物车可以显示你预定的饭菜，并进行支付，搜索功能还没有实现。

??界面是我同学设计的，我只是个丑打代码的，下面我会把全部源码放出来，BUG无可避免，还请酌情参考。

结束语

??看起来好像代码量比较多，因为本该分成几个类的代码，被我放在了一起，但不影响运行结果，图片我这里也有保留，需要的可以私我。部分功能还未实现，以后应该也不会给它实现，太懒了，喜欢的话就交给你们了。
??
??前几篇的文章有人问我要全部代码，我在这说一下，每次放源码，我都会毫无保留的把代码放出来，你能看到的就是所有，我再穷也不会在这里恰饭，开源不是理想主义，目的是分享知识。
??
??感谢大家的喜欢。
