RelationSetRef

public struct RelationSetRef : RelationSetProtocol, GWeakCapturing

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.

The RelationSetRef type acts as a lightweight Swift reference to an underlying AtkRelationSet instance. It exposes methods that can operate on this data type through RelationSetProtocol conformance. Use RelationSetRef only as an unowned reference to an existing AtkRelationSet instance.

  • ptr 
    Untyped pointer to the underlying `AtkRelationSet` instance.

    For type-safe access, use the generated, typed pointer relation_set_ptr property instead.
