.. _class_TreeItem:
TreeItem
========
**继承：** :ref:`Object<class_Object>`
代表 :ref:`Tree<class_Tree>` 中某个项目的内部控件。
.. rst-class:: classref-introduction-group
描述
----
:ref:`Tree<class_Tree>` 控件中的单个项目。可以包含其他 **TreeItem** 作为子级，从而创建层级结构。还可以包含文本和按钮。\ **TreeItem** 不是 :ref:`Node<class_Node>`\ ，在 :ref:`Tree<class_Tree>` 内部使用。
创建 **TreeItem** 请使用 :ref:`Tree.create_item()<class_Tree_method_create_item>` 或 :ref:`create_child()<class_TreeItem_method_create_child>`\ 。移除 **TreeItem** 请使用 :ref:`Object.free()<class_Object_method_free>`\ 。
\ **注意：**\ 按钮的 ID 值为 32 位，与始终为 64 位的 :ref:`int<class_int>` 不同。取值范围为 ``-2147483648`` 到 ``2147483647``\ 。
