说明： Virtual Treeview是一个“纯VCL”控件，这意味着它不是基于任何系统控件，而是重新编写的。正如它的名字已经表明，这个控件与其他这类控件相比，使用了一个不同的树管理模式。它不知道它所管理的数据是什么东西（除了它的大小），甚至没有一个节点的标题。一切都获取于通过应用程序的事件（或通过派生覆盖方法）。Virtual Treeview是经过精心设计和彻底的测试。这个控件证明了它的概念以及在许多商业产品和免费软件的项目中都很健康的运行。
Virtual Treeview是非常快的。增加一百万节点只需要700毫秒。需要很少的内存开销。很适合高速接入，遍历一百万个节点只需要不到0.5秒的时间。支持多选，支持背景图片，支持复选框，支持右键菜单，支持节点排序，支持Unicode，支持拖曳，支持剪贴板，支持多行列标题等等。
(Virtual treeview is a "pure VCL" control, which means that it is not based on any system control, but is rewritten. As its name indicates, this control uses a different tree management mode than other controls of this type. It doesn't know what the data it manages (except for its size), or even the title of a node. Everything is captured by events through the application (or by derived override methods). Virtual treeview has been carefully designed and thoroughly tested. This control proves its concept and works well in many commercial products and free software projects.
Virtual treeview is very fast. It takes only 700 milliseconds to add a million nodes. Requires very little memory overhead. It is very suitable for high-speed access. It takes less than 0.5 seconds to traverse a million nodes. It supports multiple selection, background image, check box, right-click menu, node sorting, Unicode, drag, clipboard, multi row and row titles, etc.)
