- EditorResourcePreview
- =====================
- **Inherits:** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
- Helper to generate previews of resources or files.
- Description
- -----------
- This object is used to generate previews for resources of 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>`.

- Signals
- -------
- .. _class_EditorResourcePreview_signal_preview_invalidated:
- - **preview_invalidated** **(** :ref:`String<class_String>` path **)**
- Emitted if a preview was invalidated (changed). ``path`` corresponds to the path of the preview.
- Method Descriptions
- -------------------
- .. _class_EditorResourcePreview_method_add_preview_generator:
- - void **add_preview_generator** **(** :ref:`EditorResourcePreviewGenerator<class_EditorResourcePreviewGenerator>` generator **)**
- Create an own, custom preview generator.
- ----
- .. _class_EditorResourcePreview_method_check_for_invalidation:
- - void **check_for_invalidation** **(** :ref:`String<class_String>` path **)**
- Check if the resource changed, if so, it will be invalidated and the corresponding signal emitted.
- ----
- .. _class_EditorResourcePreview_method_queue_edited_resource_preview:
- - void **queue_edited_resource_preview** **(** :ref:`Resource<class_Resource>` resource, :ref:`Object<class_Object>` receiver, :ref:`StringName<class_StringName>` receiver_func, :ref:`Variant<class_Variant>` userdata **)**
- 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:
- - void **queue_resource_preview** **(** :ref:`String<class_String>` path, :ref:`Object<class_Object>` receiver, :ref:`StringName<class_StringName>` receiver_func, :ref:`Variant<class_Variant>` userdata **)**
- 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.
- \ **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_remove_preview_generator:
- - void **remove_preview_generator** **(** :ref:`EditorResourcePreviewGenerator<class_EditorResourcePreviewGenerator>` generator **)**
- Removes a custom preview generator.
