A plugin that advanced tooltip for its handled resource type.
Resource tooltip plugins are used by [FileSystemDock] to generate customized tooltips for specific resources. E.g. tooltip for a [Texture2D] displays a bigger preview and the texture's dimensions. A plugin must be first registered with [method FileSystemDock.add_resource_tooltip_plugin]. When the user hovers a resource in filesystem dock which is handled by the plugin, [method _make_tooltip_for_path] is called to create the tooltip. It works similarly to [method Control._make_custom_tooltip].
Return [code]true[/code] if the plugin is going to handle the given [Resource] [param type].
Create and return a tooltip that will be displayed when the user hovers a resource under the given [param path] in filesystem dock. The [param metadata] dictionary is provided by preview generator (see [method EditorResourcePreviewGenerator._generate]). [param base] is the base default tooltip, which is a [VBoxContainer] with a file name, type and size labels. If another plugin handled the same file type, [param base] will be output from the previous plugin. For best result, make sure the base tooltip is part of the returned [Control]. [b]Note:[/b] It's unadvised to use [method ResourceLoader.load], especially with heavy resources like models or textures, because it will make the editor unresponsive when creating the tooltip. You can use [method request_thumbnail] if you want to display a preview in your tooltip. [b]Note:[/b] If you decide to discard the [param base], make sure to call [method Node.queue_free], because it's not freed automatically. [codeblock] func _make_tooltip_for_path(path, metadata, base): var t_rect = TextureRect.new() request_thumbnail(path, t_rect) base.add_child(t_rect) # The TextureRect will appear at the bottom of the tooltip. return base [/codeblock]
Requests a thumbnail for the given [TextureRect]. The thumbnail is created asynchronously by [EditorResourcePreview] and automatically set when available.
