Description
-----------

This shows a tree of items that can be selected, expanded and collapsed. The tree can have multiple columns with custom controls like text editing, buttons and popups. It can be useful for structured displays and interactions.

Trees are built via code, using :ref:`TreeItem<class_TreeItem>` objects to create the structure. They have a single root but multiple roots can be simulated if a dummy hidden root is added.

::

    func _ready():
        var tree = Tree.new()
        var root = tree.create_item()
        tree.set_hide_root(true)
        var child1 = tree.create_item(root)
        var child2 = tree.create_item(root)
        var subchild1 = tree.create_item(child1)
        subchild1.set_text(0, "Subchild1")

- :ref:`int<class_int>` **get_column_at_position** **(** :ref:`Vector2<class_Vector2>` position **)** const

Returns the column index under the given point.

.. _class_Tree_method_get_column_title:

- :ref:`String<class_String>` **get_column_title** **(** :ref:`int<class_int>` column **)** const

Returns the column's title.

.. _class_Tree_method_get_column_width:

- :ref:`int<class_int>` **get_column_width** **(** :ref:`int<class_int>` column **)** const

Returns the column's width in pixels.

.. _class_Tree_method_get_custom_popup_rect:

- :ref:`Rect2<class_Rect2>` **get_custom_popup_rect** **(** **)** const

Returns the rectangle for custom popups. Helper to create custom cell controls that display a popup. See :ref:`TreeItem.set_cell_mode<class_TreeItem_method_set_cell_mode>`.

.. _class_Tree_method_get_drop_section_at_position:

- :ref:`int<class_int>` **get_drop_section_at_position** **(** :ref:`Vector2<class_Vector2>` position **)** const

If :ref:`drop_mode_flags<class_Tree_property_drop_mode_flags>` includes :ref:`DROP_MODE_INBETWEEN<class_Tree_constant_DROP_MODE_INBETWEEN>`, returns -1 if ``position`` is the upper part of a tree item at that position, 1 for the lower part, and additionally 0 for the middle part if :ref:`drop_mode_flags<class_Tree_property_drop_mode_flags>` includes :ref:`DROP_MODE_ON_ITEM<class_Tree_constant_DROP_MODE_ON_ITEM>`.

Otherwise, returns 0. If there are no tree items at ``position``, returns -100.
