BoxContainer
============

**Inherits:** :ref:`Container<class_Container>` **<** :ref:`Control<class_Control>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

**Inherited By:** :ref:`ColorPicker<class_ColorPicker>`, :ref:`HBoxContainer<class_HBoxContainer>`, :ref:`VBoxContainer<class_VBoxContainer>`

Base class for box containers.

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

Arranges child :ref:`Control<class_Control>` nodes vertically or horizontally, and rearranges them automatically when their minimum size changes.

Enumerations
------------

.. _enum_BoxContainer_AlignmentMode:

.. _class_BoxContainer_constant_ALIGNMENT_BEGIN:

.. _class_BoxContainer_constant_ALIGNMENT_CENTER:

.. _class_BoxContainer_constant_ALIGNMENT_END:

enum **AlignmentMode**:

- **ALIGNMENT_BEGIN** = **0** --- The child controls will be arranged at the beginning of the container, i.e. top if orientation is vertical, left if orientation is horizontal (right for RTL layout).

- **ALIGNMENT_CENTER** = **1** --- The child controls will be centered in the container.

- **ALIGNMENT_END** = **2** --- The child controls will be arranged at the end of the container, i.e. bottom if orientation is vertical, right if orientation is horizontal (left for RTL layout).

Property Descriptions
---------------------

.. _class_BoxContainer_property_alignment:

- :ref:`AlignmentMode<enum_BoxContainer_AlignmentMode>` **alignment**

+-----------+----------------------+
| *Default* | ``0``                |
+-----------+----------------------+
| *Setter*  | set_alignment(value) |
+-----------+----------------------+
| *Getter*  | get_alignment()      |
+-----------+----------------------+

The alignment of the container's children (must be one of :ref:`ALIGNMENT_BEGIN<class_BoxContainer_constant_ALIGNMENT_BEGIN>`, :ref:`ALIGNMENT_CENTER<class_BoxContainer_constant_ALIGNMENT_CENTER>`, or :ref:`ALIGNMENT_END<class_BoxContainer_constant_ALIGNMENT_END>`).

----

.. _class_BoxContainer_property_vertical:

- :ref:`bool<class_bool>` **vertical**

+-----------+---------------------+
| *Default* | ``false``           |
+-----------+---------------------+
| *Setter*  | set_vertical(value) |
+-----------+---------------------+
| *Getter*  | is_vertical()       |
+-----------+---------------------+

If ``true``, the ``BoxContainer`` will arrange its children vertically, rather than horizontally.

Can't be changed when using :ref:`HBoxContainer<class_HBoxContainer>` and :ref:`VBoxContainer<class_VBoxContainer>`.

Method Descriptions
-------------------

.. _class_BoxContainer_method_add_spacer:

- :ref:`Control<class_Control>` **add_spacer** **(** :ref:`bool<class_bool>` begin **)**

Adds a :ref:`Control<class_Control>` node to the box as a spacer. If ``begin`` is ``true``, it will insert the :ref:`Control<class_Control>` node in front of all other children.

Theme Property Descriptions
---------------------------

.. _class_BoxContainer_theme_constant_separation:

- :ref:`int<class_int>` **separation**

+-----------+-------+
| *Default* | ``4`` |
+-----------+-------+

The space between the ``BoxContainer``'s elements, in pixels.
