win32 Api Listctrl 添加样式LVS_OWNERDRAWFIXED 不显示复选框

玉生香 2021-08-10 18:57:01

不是MFC。Win32Api 编程。

直接上代码，代码上带注释

//如果支持LVS_OWNERDRAWFIXED 则不见了复选框，去掉则收不到WM_MEASUREITEM 消息。

VC/MFC社区版块或许是CSDN最“古老”的版块了，记忆之中，与CSDN的年龄几乎差不多。随着时间的推移，MFC技术渐渐的偏离了开发主流，若干年之后的今天，当我们面对着微软的这个经典之笔，内心充满着敬意，那些曾经的记忆，可以说代表着二十年前曾经的辉煌……
向经典致敬，或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天，我们期待着MFC技术能够恢复其曾经的辉煌，或许这个期待会永远成为一种“梦想”，或许一切皆有可能……
我们希望这个版块可以很好的适配Web时代，期待更好的互联网技术能够使得MFC技术框架得以重现活力，……
