|
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].

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.

base.add_child(t_rect) # The TextureRect will appear at the bottom of the tooltip.
