标签:ref datetime += == 网上 ret eve reac 完美 在网上搜了很多办法,包括width=-1、-2,效果都不理想。自己摸索了个办法: 1:设计时,先把各列尺寸大体上调好; 2:启动时记下来各列width所占的比例。 3:resize时按比例重新设置一遍各列的width. 效果相当完美,按比例缩放 C#中listView列自动适应缩放的完美效果 标签:ref datetime += == 网上 ret eve reac 完美 原文地址:https://www.cnblogs.com/HaiHong/p/11106206.htmlpublic class colSizes : Listdouble> { };
