连接打开Mysql数据库，通过table view控件显示MySQL数据库的数据，并且可以在table view控件上进行数据修改，修改的内容可以保存到数据库上；table view的显示的数据还可以和界面组件通过字段进行数据的映射，修改组件的内容会反馈到tableview控件上并保存；table view上还有自定义的combobox控件。

Qt5.12.6 msvc2019 static 自编译的qt5 静态库 vc14 vc15可用,包含发布版和调试版 安装路径: D:\Qt\Qt5.12.6\5.12.6 core+gui+widget 发布体积为10mb左右

本资源为Q5.12编译成功的libCAD源码。 1.libCAD是Qcad的一个分支，里面存有三个开源库libdxfrw、jwwlib、muparser源码以及使用Qt实现CAD绘图功能的源码。 2.适合作为CAD二次开发、dxf二次开发、dwg二次开发的参考 3.适合作为了解和学习libCAD项目的资料
