 1 | # cpp-qt-manageSystem
 2 | ## 基于C++和qt的超市商品管理系统
 3 | wtu 计科21级面向对象课程设计 
 4 | 
 5 | 
 6 | ### 一 简要介绍
 7 | 1.本项目为面向对象程序设计的大作业，基于Qt creator进行开发，Qt框架版本6.4.1，编译环境MINGW 11.2.0。
 8 | 
 9 | 2.项目结构简介：关于系统逻辑部分的代码的头文件在head文件夹中，源文件在s文件夹中。与图形界面相关的代码在项目头文件和源文件的文件夹内。
10 | 应用程序内使用的一些图片、动图在rc文件夹内。
11 | 
12 | 3.UML类图：
13 | 
14 | ![image](https://user-images.githubusercontent.com/62981633/210293721-0eb891fa-3d48-40a9-a200-b0c28bec0b27.png)
15 | 
16 | 
17 | ### 二 使用方式
18 | 1.可下载源码使用Qt creator进行构建后运行
19 | 
20 | 2.若无Qt环境，可以直接下载Releases版本运行，无需任何依赖。若需要测试用例，可将文件夹内的测试数据文件夹内的文件移动至可执行程序目录中。
21 | 若不移动，则系统无初始数据，需要输入初始密码。
22 | 
23 | 
24 | ### 三 运行截图
25 | 
26 |   #### 登录界面

28 |   
29 |    #### 商品信息输入窗口
