emit_signal(SNAME("object_id_selected"), p_property, p_id);
}
void EditorPropertyArray::update_property() {
	Variant array = get_edited_property_value();
	String array_type_name = Variant::get_type_name(array_type);
	if (array_type == Variant::ARRAY && subtype != Variant::NIL) {
		String type_name;
		if (subtype == Variant::OBJECT && (subtype_hint == PROPERTY_HINT_RESOURCE_TYPE || subtype_hint == PROPERTY_HINT_NODE_TYPE)) {
			type_name = subtype_hint_string;
		} else {
			type_name = Variant::get_type_name(subtype);
		}
		array_type_name = vformat("%s[%s]", array_type_name, type_name);
	}
	if (array.get_type() == Variant::NIL) {
		edit->set_text(vformat(TTR("(Nil) %s"), array_type_name));
		edit->set_pressed(false);
		if (container) {
