VirtualTrees完整可用。 Virtual Treeview is designed for Delphi 4 and higher and can also be used with Borland C++ Builder 4 and up. The entire implementation covers only 4 files: 1、VirtualTrees.pas - the code 2、VirtualTrees.dcr - the design time resource 3、VirtualTrees.res - the run time resource 4、DFS.inc - a small include file written by Brad Stowers used to determine the Delphi or BCB version you are trying to compile with With these four files it is extremely easy to install the trees. Just put the files into your library folder and add VirtualTrees.pas to any of your packages. I'm sure you have at least one third-party package, haven't you? If not just create one via Component | Install Component | Into new package

在TVHeader里添加了一个属性"HeaderAlignment"用来设置头部标题文字位置.以前的Alignment只用来设置Node节点的文字的位置.解压后将VirtualTrees.pas复盖旧的文件,,再重新安装一次VirtualTrees的控件就可以使用了.
