Atk.RelationSet – atk – Vala Binding Reference

Description:

[ CCode ( type_id = "atk_relation_set_get_type ()" ) ]
public class RelationSet : Object

The AtkRelationSet held by an object establishes its relationships with objects beyond the normal "parent/child" hierarchical relationships that all user interface objects have.

AtkRelationSets establish whether objects are labelled or controlled by other components, share group membership with other components (for instance within a radio-button group), or share content which "flows" between them, among other types of possible relationships.
