Delphi:Delphi使用TreeView控件实现的导航界面，左侧的树控菜单就是基于TreeView控件，在一般的信息管理系统中，树形菜单使用广泛，通过本演示源码，你将学会不使用外部控件而实现Delphi窗体中的TreeView树控效果，我想是比较实用的源码例子。

-Delphi: Delphi TreeView control is achieved using the navigation interface, the tree control menu on the left is based on the TreeView control, information management systems in general, the tree menu widely used by the demo source code, you will learn to be achieved without using external controls Delphi Forms TreeView tree control effect, I think it is more practical source code examples.
