FlowContainer
=============

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

**Inherited By:** :ref:`HFlowContainer<class_HFlowContainer>`, :ref:`VFlowContainer<class_VFlowContainer>`

A container that arranges its child controls horizontally or vertically and wraps them around at the borders.

.. rst-class:: classref-introduction-group

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

A container that arranges its child controls horizontally or vertically and wraps them around at the borders. This is similar to how text in a book wraps around when no more words can fit on a line.

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

.. _enum_FlowContainer_AlignmentMode:

.. rst-class:: classref-enumeration

enum **AlignmentMode**:

.. _class_FlowContainer_constant_ALIGNMENT_BEGIN:

.. rst-class:: classref-enumeration-constant

:ref:`AlignmentMode<enum_FlowContainer_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).

.. _class_FlowContainer_constant_ALIGNMENT_CENTER:

.. rst-class:: classref-enumeration-constant

:ref:`AlignmentMode<enum_FlowContainer_AlignmentMode>` **ALIGNMENT_CENTER** = ``1``

The child controls will be centered in the container.

.. _class_FlowContainer_constant_ALIGNMENT_END:

.. rst-class:: classref-enumeration-constant

:ref:`AlignmentMode<enum_FlowContainer_AlignmentMode>` **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_FlowContainer_property_alignment:

.. rst-class:: classref-property

:ref:`AlignmentMode<enum_FlowContainer_AlignmentMode>` **alignment** = ``0``

.. rst-class:: classref-property-setget

- void **set_alignment** **(** :ref:`AlignmentMode<enum_FlowContainer_AlignmentMode>` value **)**
- :ref:`AlignmentMode<enum_FlowContainer_AlignmentMode>` **get_alignment** **(** **)**

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

.. rst-class:: classref-item-separator

----

.. _class_FlowContainer_property_reverse_fill:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **reverse_fill** = ``false``

.. rst-class:: classref-property-setget

- void **set_reverse_fill** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_reverse_fill** **(** **)**

If ``true``, reverses fill direction. Horizontal **FlowContainer**\ s will fill rows bottom to top, vertical **FlowContainer**\ s will fill columns right to left.

When using a vertical **FlowContainer** with a right to left :ref:`Control.layout_direction<class_Control_property_layout_direction>`, columns will fill left to right instead.

.. rst-class:: classref-item-separator

----

.. _class_FlowContainer_property_vertical:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **vertical** = ``false``

.. rst-class:: classref-property-setget

- void **set_vertical** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_vertical** **(** **)**

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

Can't be changed when using :ref:`HFlowContainer<class_HFlowContainer>` and :ref:`VFlowContainer<class_VFlowContainer>`.

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

.. _class_FlowContainer_method_get_line_count:

.. rst-class:: classref-method

:ref:`int<class_int>` **get_line_count** **(** **)** |const|

Returns the current line count.

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

.. _class_FlowContainer_theme_constant_h_separation:

.. rst-class:: classref-themeproperty

:ref:`int<class_int>` **h_separation** = ``4``

The horizontal separation of children nodes.

.. rst-class:: classref-item-separator

----

.. _class_FlowContainer_theme_constant_v_separation:

.. rst-class:: classref-themeproperty

:ref:`int<class_int>` **v_separation** = ``4``

The vertical separation of children nodes.
