Once the preview is ready, the [param receiver]'s [param receiver_func] will be called. The [param receiver_func] must take the following four arguments: [String] path, [Texture2D] preview, [Texture2D] thumbnail_preview, [Variant] userdata. [param userdata] can be anything, and will be returned when [param receiver_func] is called. [b]Note:[/b] If it was not possible to create the preview the [param receiver_func] will still be called, but the preview will be null. </description> </method> <method name="queue_resource_preview"> <return type="void" /> <param index="0" name="path" type="String" /> <param index="1" name="receiver" type="Object" /> <param index="2" name="receiver_func" type="StringName" /> <param index="3" name="userdata" type="Variant" /> <description> Queue a resource file located at [param path] for preview.
