Relation

Required Methods

fn add_target(&self, target: &impl IsA<Object>)

Adds the specified AtkObject to the target for the relation, if it is not already present. See also AtkObjectExt::add_relationship().

target

an Object

fn relation_type(&self) -> RelationType

Gets the type of self

Returns

the type of self

fn target(&self) -> Vec<Object>

Gets the target list of self

Returns

the target list of self

fn remove_target(&self, target: &impl IsA<Object>) -> bool

Remove the specified AtkObject from the target for the relation.

target

an Object

Returns

TRUE if the removal is successful.

fn set_relation_type(&self, relation_type: RelationType)

fn set_target(&self, target: Option<&ValueArray>)

fn connect_relation_type_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_target_notify<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
