Class EditorResourceTooltipPlugin

A plugin that advanced tooltip for its handled resource type.

Inheritance
EditorResourceTooltipPlugin

Remarks

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 FileSystemDock.add_resource_tooltip_plugin. When the user hovers a resource in filesystem dock which is handled by the plugin, EditorResourceTooltipPlugin._make_tooltip_for_path is called to create the tooltip. It works similarly to Control._make_custom_tooltip.

Methods

_handles(String)

Qualifiers: virtualconst

Return true if the plugin is going to handle the given Resource type.

bool _handles(String type)

Parameters

type String

_make_tooltip_for_path(String, Dictionary, Control)

Qualifiers: virtualconst

Create and return a tooltip that will be displayed when the user hovers a resource under the given path in filesystem dock.

The metadata dictionary is provided by preview generator (see EditorResourcePreviewGenerator._generate).

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, base will be output from the previous plugin. For best result, make sure the base tooltip is part of the returned Control.

Note: It's unadvised to use ResourceLoader.load, especially with heavy resources like models or textures, because it will make the editor unresponsive when creating the tooltip. You can use EditorResourceTooltipPlugin.request_thumbnail if you want to display a preview in your tooltip.

Note: If you decide to discard the base, make sure to call queue_free, because it's not freed automatically.

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
