Qt写计算机协会值班签到系统
本文已被浏览13170次
计算机协会旧版的签到系统是用Flash+PHP使用Mysql数据库来写的.但是在使用过程中发现有些同学在签到的时候容易不小心的就关掉WAMP,于是Mysql和Apache就被干掉了,只剩下一个Flash根本没有办法和Mysql通信,开学纳新后,决定重新写一下V2.0版本
这个程序没有和其他设备共用数据库的必要,选用了SQLite,SQLite和Mysql类似,只是少了一些函数方面的功能,其他方面在SQLite3版本上和Mysql基本操作一样了.
这个程序设计了五个UI界面(关于,帮助,主窗口,值班窗口,管理窗口),这里只介绍后面三个界面.每个界面都有对应的cpp文件和.h头文件.
