Description

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