关于TbsPNGImageList:的问题 1. You must install PNGImage library from http://pngdelphi.sourceforge.net 2. Add bspngimagelist.pas to the BSF package and recompile it. 3. Use TbsPNGImageList in all controls (see PngImages property), because it inherited from standard TCustomImageList. 我按上面1,2步骤都安装好了,但为什么还是没有pngimagelist控件呢,官方上说要注册完才有pngimagelist控件,但这个版本都提供源代码了啊,请问这个问题该怎么解决呢
