Types and Values
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.
AtkRelationSet * atk_relation_set_new (
Creates a new empty relation set.
a new AtkRelationSet
gboolean atk_relation_set_contains (
Determines whether the relation set contains a relation that matches the specified type.
void atk_relation_set_remove (
Removes a relation from the relation set. This function unref's the AtkRelation so it will be deleted unless there is another reference to it.
void atk_relation_set_add (
Add a new relation to the current relation set if it is not already present. This function ref's the AtkRelation so the caller of this function should unref it to ensure that it will be destroyed when the AtkRelationSet is destroyed.
gint atk_relation_set_get_n_relations (
Determines the number of relations in a relation set.
AtkRelation * atk_relation_set_get_relation (
Determines the relation at the specified position in the relation set.
a gint representing a position in the set, starting from 0.
AtkRelation * atk_relation_set_get_relation_by_type (
Finds a relation that matches the specified type.
void atk_relation_set_add_relation_by_type (
Add a new relation of the specified type with the specified target to the current relation set if the relation set does not contain a relation of that type. If it is does contain a relation of that typea the target is added to the relation.
