.. _class_TreeItem:
TreeItem
========
**繼承：** :ref:`Object<class_Object>`
代表 :ref:`Tree<class_Tree>` 中某個專案的內部控制項。
.. rst-class:: classref-introduction-group
說明
----
:ref:`Tree<class_Tree>` 控制項中的單個專案。可以包含其他 **TreeItem** 作為子級，從而建立層級結構。還可以包含文字和按鈕。\ **TreeItem** 不是 :ref:`Node<class_Node>`\ ，在 :ref:`Tree<class_Tree>` 內部使用。
要建立 **TreeItem**\ ，請使用 :ref:`Tree.create_item()<class_Tree_method_create_item>` 或 :ref:`create_child()<class_TreeItem_method_create_child>`\ 。要移除 **TreeItem**\ ，請使用 :ref:`Object.free()<class_Object_method_free>`\ 。
\ **注意：**\ 按鈕的 ID 值為 32 位，與始終為 64 位的 :ref:`int<class_int>` 不同。取值範圍為 ``-2147483648`` 到 ``2147483647``\ 。

.. _class_TreeItem_constant_CELL_MODE_STRING:
.. rst-class:: classref-enumeration-constant
:ref:`TreeCellMode<enum_TreeItem_TreeCellMode>` **CELL_MODE_STRING** = ``0``
Cell shows a string label, optionally with an icon. When editable, the text can be edited using a :ref:`LineEdit<class_LineEdit>`, or a :ref:`TextEdit<class_TextEdit>` popup if :ref:`set_edit_multiline()<class_TreeItem_method_set_edit_multiline>` is used.
.. _class_TreeItem_constant_CELL_MODE_CHECK:
.. rst-class:: classref-enumeration-constant
:ref:`TreeCellMode<enum_TreeItem_TreeCellMode>` **CELL_MODE_CHECK** = ``1``
Cell shows a checkbox, optionally with text and an icon. The checkbox can be pressed, released, or indeterminate (via :ref:`set_indeterminate()<class_TreeItem_method_set_indeterminate>`). The checkbox can't be clicked unless the cell is editable.
.. _class_TreeItem_constant_CELL_MODE_RANGE:
.. rst-class:: classref-enumeration-constant
:ref:`TreeCellMode<enum_TreeItem_TreeCellMode>` **CELL_MODE_RANGE** = ``2``
Cell shows a numeric range. When editable, it can be edited using a range slider. Use :ref:`set_range()<class_TreeItem_method_set_range>` to set the value and :ref:`set_range_config()<class_TreeItem_method_set_range_config>` to configure the range.
This cell can also be used in a text dropdown mode when you assign a text with :ref:`set_text()<class_TreeItem_method_set_text>`. Separate options with a comma, e.g. ``"Option1,Option2,Option3"``.
.. _class_TreeItem_constant_CELL_MODE_ICON:
.. rst-class:: classref-enumeration-constant
:ref:`TreeCellMode<enum_TreeItem_TreeCellMode>` **CELL_MODE_ICON** = ``3``
Cell shows an icon. It can't be edited nor display text. The icon is always centered within the cell.
.. _class_TreeItem_constant_CELL_MODE_CUSTOM:
.. rst-class:: classref-enumeration-constant
:ref:`TreeCellMode<enum_TreeItem_TreeCellMode>` **CELL_MODE_CUSTOM** = ``4``
Cell shows as a clickable button. It will display an arrow similar to :ref:`OptionButton<class_OptionButton>`, but doesn't feature a dropdown (for that you can use :ref:`CELL_MODE_RANGE<class_TreeItem_constant_CELL_MODE_RANGE>`). Clicking the button emits the :ref:`Tree.item_edited<class_Tree_signal_item_edited>` signal. The button is flat by default, you can use :ref:`set_custom_as_button()<class_TreeItem_method_set_custom_as_button>` to display it with a :ref:`StyleBox<class_StyleBox>`.
This mode also supports custom drawing using :ref:`set_custom_draw_callback()<class_TreeItem_method_set_custom_draw_callback>`.
