NinePatchRect
=============

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

Scalable texture-based frame that tiles the texture's centers and sides, but keeps the corners' original size. Perfect for panels and dialog boxes.

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

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

Also known as 9-slice panels, NinePatchRect produces clean panels of any size, based on a small texture. To do so, it splits the texture in a 3×3 grid. When you scale the node, it tiles the texture's sides horizontally or vertically, the center on both axes but it doesn't scale or tile the corners.

Signals
-------

.. _class_NinePatchRect_signal_texture_changed:

**texture_changed** **(** **)**

Emitted when the node's texture changes.

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

.. _enum_NinePatchRect_AxisStretchMode:

.. rst-class:: classref-enumeration

enum **AxisStretchMode**:

.. _class_NinePatchRect_constant_AXIS_STRETCH_MODE_STRETCH:

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

:ref:`AxisStretchMode<enum_NinePatchRect_AxisStretchMode>` **AXIS_STRETCH_MODE_STRETCH** = ``0``

Stretches the center texture across the NinePatchRect. This may cause the texture to be distorted.

.. _class_NinePatchRect_constant_AXIS_STRETCH_MODE_TILE:

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

:ref:`AxisStretchMode<enum_NinePatchRect_AxisStretchMode>` **AXIS_STRETCH_MODE_TILE** = ``1``

Repeats the center texture across the NinePatchRect. This won't cause any visible distortion. The texture must be seamless for this to work without displaying artifacts between edges.

\ **Note:** Only supported when using the GLES3 renderer. When using the GLES2 renderer, this will behave like :ref:`AXIS_STRETCH_MODE_STRETCH<class_NinePatchRect_constant_AXIS_STRETCH_MODE_STRETCH>`.

.. _class_NinePatchRect_constant_AXIS_STRETCH_MODE_TILE_FIT:

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

:ref:`AxisStretchMode<enum_NinePatchRect_AxisStretchMode>` **AXIS_STRETCH_MODE_TILE_FIT** = ``2``

Repeats the center texture across the NinePatchRect, but will also stretch the texture to make sure each tile is visible in full. This may cause the texture to be distorted, but less than :ref:`AXIS_STRETCH_MODE_STRETCH<class_NinePatchRect_constant_AXIS_STRETCH_MODE_STRETCH>`. The texture must be seamless for this to work without displaying artifacts between edges.

\ **Note:** Only supported when using the GLES3 renderer. When using the GLES2 renderer, this will behave like :ref:`AXIS_STRETCH_MODE_STRETCH<class_NinePatchRect_constant_AXIS_STRETCH_MODE_STRETCH>`.
