本文主要是介绍MFC界面美化第四篇----自绘list列表(重绘列表)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1.前言
最近发现读者对我的mfc美化的专栏比较感兴趣，因此在这里进行续写，这里我会计划写几个连续的篇章，包括对MFC按钮的美化，菜单栏的美化，标题栏的美化，list列表的美化，直到最后形成一个完整的成品效果。
2.最终效果展示
3.思路分析
1.编写mfc的list的派生类对 列表进行重绘
2.list和其他的空间有些区别，要分别对标题栏，和内容栏进行重绘。
4.实现的过程
1.在mfc界面，增加空间list
2.修改list的属性
边框:false
静态边缘：false
视图:Reporte
无滚动：true
3.声明list的变量
