=====================

**Hereda:** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

A node used to generate previews of resources or files.

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

Descripción
----------------------

This node is used to generate previews for resources or files.

\ **Note:** This class shouldn't be instantiated directly. Instead, access the singleton using :ref:`EditorInterface.get_resource_previewer()<class_EditorInterface_method_get_resource_previewer>`.

Señales
--------------

.. _class_EditorResourcePreview_signal_preview_invalidated:

.. rst-class:: classref-signal

**preview_invalidated**\ (\ path\: :ref:`String<class_String>`\ ) :ref:`🔗<class_EditorResourcePreview_signal_preview_invalidated>`

Se emite si una vista previa se ha invalidado (cambiado). ``path`` corresponde a la ruta de la vista previa.

.. _class_EditorResourcePreview_method_add_preview_generator:

.. rst-class:: classref-method

|void| **add_preview_generator**\ (\ generator\: :ref:`EditorResourcePreviewGenerator<class_EditorResourcePreviewGenerator>`\ ) :ref:`🔗<class_EditorResourcePreview_method_add_preview_generator>`

Crear un generador de previsualización propio y personalizado.

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

.. _class_EditorResourcePreview_method_check_for_invalidation:

.. rst-class:: classref-method

|void| **check_for_invalidation**\ (\ path\: :ref:`String<class_String>`\ ) :ref:`🔗<class_EditorResourcePreview_method_check_for_invalidation>`

Comprueba si el recurso ha cambiado, si es así, se invalidará y se emitirá la señal correspondiente.

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

.. _class_EditorResourcePreview_method_queue_edited_resource_preview:

.. rst-class:: classref-method

|void| **queue_edited_resource_preview**\ (\ resource\: :ref:`Resource<class_Resource>`, receiver\: :ref:`Object<class_Object>`, receiver_func\: :ref:`StringName<class_StringName>`, userdata\: :ref:`Variant<class_Variant>`\ ) :ref:`🔗<class_EditorResourcePreview_method_queue_edited_resource_preview>`

Queue the ``resource`` being edited for preview. Once the preview is ready, the ``receiver``'s ``receiver_func`` will be called. The ``receiver_func`` must take the following four arguments: :ref:`String<class_String>` path, :ref:`Texture2D<class_Texture2D>` preview, :ref:`Texture2D<class_Texture2D>` thumbnail_preview, :ref:`Variant<class_Variant>` userdata. ``userdata`` can be anything, and will be returned when ``receiver_func`` is called.

\ **Note:** If it was not possible to create the preview the ``receiver_func`` will still be called, but the preview will be ``null``.

.. _class_EditorResourcePreview_method_queue_resource_preview:

Queue a resource file located at ``path`` for preview. Once the preview is ready, the ``receiver``'s ``receiver_func`` will be called. The ``receiver_func`` must take the following four arguments: :ref:`String<class_String>` path, :ref:`Texture2D<class_Texture2D>` preview, :ref:`Texture2D<class_Texture2D>` thumbnail_preview, :ref:`Variant<class_Variant>` userdata. ``userdata`` can be anything, and will be returned when ``receiver_func`` is called.

|void| **remove_preview_generator**\ (\ generator\: :ref:`EditorResourcePreviewGenerator<class_EditorResourcePreviewGenerator>`\ ) :ref:`🔗<class_EditorResourcePreview_method_remove_preview_generator>`

Elimina un generador de previsualización personalizado.
