## Detailed Description

An Atk::Relation describes a relation between an object and one or more other objects.

The actual relations that an object has with other objects are defined as an Atk::RelationSet, which is a set of Atk::Relations.

## Constructor & Destructor Documentation

## ◆ Relation() [1/2]

Atk::Relation::Relation | ( | Relation&& | src | ) |
| noexcept

## ◆ ~Relation()

Atk::Relation::~Relation | ( |  | ) |
| overridenoexcept

## ◆ Relation() [2/2]

## Member Function Documentation

## ◆ add_target()

void Atk::Relation::add_target | ( | const Glib::RefPtr< Atk::Object >& | target | ) |

Adds the specified AtkObject to the target for the relation, if it is not already present.

See also Atk::Object::add_relationship().

Since atkmm 1.9:

Parameters

  target | An Atk::Object.

## ◆ create()

static Glib::RefPtr<Relation> Atk::Relation::create | ( | const Glib::ArrayHandle< Glib::RefPtr< Atk::Object > >& | targets,
|  | RelationType | relationship = `RELATION_NULL`
| ) |  |
| static

## ◆ get_relation_type()

RelationType Atk::Relation::get_relation_type | ( |  | ) | const

Gets the type of relation.

Returns
  The type of relation.

## ◆ get_target() [1/2]

Glib::ArrayHandle< Glib::RefPtr<Atk::Object> > Atk::Relation::get_target | ( |  | ) |

## ◆ get_target() [2/2]

Glib::ArrayHandle< Glib::RefPtr<const Atk::Object> > Atk::Relation::get_target | ( |  | ) | const

## ◆ get_type()

static GType Atk::Relation::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

## ◆ gobj() [1/2]

AtkRelation* Atk::Relation::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

## ◆ gobj() [2/2]

const AtkRelation* Atk::Relation::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

## ◆ gobj_copy()

AtkRelation* Atk::Relation::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

## ◆ operator=()

Relation& Atk::Relation::operator= | ( | Relation&& | src | ) |
| noexcept

## Friends And Related Function Documentation

## ◆ wrap()

Glib::RefPtr< Atk::Relation > wrap | ( | AtkRelation * | object,
|  | bool | take_copy = `false`
| ) |  |
| related

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns
  A C++ instance that wraps this C instance.
