用Python PyQt5制作校园订餐系统界面_用python做一个具有gui界面的点餐系统

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。
