Is there a way to add exported variables to a group?

Question

For example, the sprite node has this piece of code:

ADD_GROUP("Region", "region_");

Which creates the Region group, with it's child variables Enabled, Rect and Filter Clip

Is there a way to accomplish a similar result using GDScript?

Hi, as far as I can tell, in 3.0 there is no simple way to do this, although there seems to have been some discussion about adding this functionality.

https://github.com/godotengine/godot/pull/10303
https://github.com/godotengine/godot/issues/4378

It is possible, though, as described by Bojidar Marinov in a post to this thread:

https://godotengine.org/qa/3196/how-add-subcategories-inspector-script-variables-section

Here is a slightly different implementation I use based on the same technique:

Scripts/PropertyList.gd

extends Object

var properties = {}

func add(name, type, default_value):
    properties[name] = {
        "hint": PROPERTY_HINT_NONE,
        "usage": PROPERTY_USAGE_DEFAULT,
        "name": name,
        "type": type,
        "value": default_value 
    }

func get(name):
    return properties[name].value

func set(name, value):
    if properties.has(name):
        properties[name].value = value

func _init(list):
    for prop in list:
        add(prop[0], prop[1], prop[2])

And then, in your scripts you can do:

tool
extends Spatial

const PropertyList = preload("res://Scripts/PropertyList.gd")

var property_list = PropertyList.new([
    ["test/foo",TYPE_STRING,"allo"],
    ["test/bar",TYPE_INT,32],
    ["other/foo",TYPE_STRING,"truc"],
    ["other/bar",TYPE_INT,8]])

func _get(property):
    return property_list.get(property)

func _set(property, value):
    property_list.set(property, value)

func _get_property_list():
    return property_list.properties.values()

Is it possible to set the type as Texture this way?
Like the TexturedButton groups it's textures under Textures category?
