### Detailed Description

An AtkRelation 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 AtkRelationSet, which is a set of AtkRelations.

### Structures

`AtkRelation`

  The AtkRelation structure should not be accessed directly.

### Convenient Construction

`atkRelation` is the equivalent of `atkRelationNew`.

### Enums and Flags

`AtkRelationType`

  Describes the type of the relation

  `null`

    Not used, represens "no relationship" or an error condition.

  `controlled-by`

    Indicates an object controlled by one or more target objects.

  `controller-for`

    Indicates an object is an controller for one or more target objects.

  `label-for`

    Indicates an object is a label for one or more target objects.

  `labelled-by`

    Indicates an object is labelled by one or more target objects.

  `member-of`

    Indicates an object is a member of a group of one or more target objects.

  `node-child-of`

    Indicates an object is a cell in a treetable which is displayed because a cell in the same column is expanded and identifies that cell.

  `flows-to`

    Indicates that the object has content that flows logically to another AtkObject in a sequential way, (for instance text-flow).

  `flows-from`

    Indicates that the object has content that flows logically from another AtkObject in a sequential way, (for instance text-flow).

  `subwindow-of`

    Indicates a subwindow attached to a component but otherwise has no connection in the UI heirarchy to that component.

  `embeds`

    Indicates that the object visually embeds another object's content, i.e. this object's content flows around another's content.

  `embedded-by`

    Inverse of `ATK_RELATION_EMBEDS`, indicates that this object's content is visualy embedded in another object.

  `popup-for`

    Indicates that an object is a popup for another object.

  `parent-window-of`

    Indicates that an object is a parent window of another object.

  `description-for`

    Indicates that another object provides descriptive information about this object; more verbose than ATK_RELATION_LABELLED_BY.

  `described-by`

    Indicates that an object provides descriptive information about another object; more verbose than ATK_RELATION_LABEL_FOR.

  `last-defined`

    Indicates an object is a cell in a treetable and is expanded to display other cells in the same column.

### Properties

`relation-type` [`AtkRelationType` : Read / Write]

  The type of the relation. Default value: ATK_RELATION_NULL

`target` [GValueArray : * : Read / Write]

  An list of the targets for the relation.
