详细介绍：C# NX二次开发：树列表控件Tree详解

大家好，今天介绍ug二次开发过程中的一个叫树列表的控件，这个控件在块UI编辑器中可以使用。

这个控件中的一些属性和方式：就是下面

// 摘要:
// Represents the Tree block in block styler automation.

// To start utilizing the tree use methods such as NXOpen.BlockStyler.Tree.InsertColumn(System.Int32,System.String,System.Int32),

// etc. It is must to insert the column on the tree before inserting any node. Node
// can be created but cannot be inserted without the column available on the tree.
// Note that some of the methods of this class such as NXOpen.BlockStyler.Tree.InsertColumn(System.Int32,System.String,System.Int32)
// must be used in or after the BlockStyler.BlockDialog.DialogShown callback after
// which tree is fully constructed and ready for use.
