#AtspiRelationType specifies a relationship between objects (possibly one-to-many or many-to-one) outside of the normal parent/child hierarchical relationship. It allows better semantic identification of how objects are associated with one another. For instance the ATSPI_RELATION_LABELLED_BY relationship may be used to identify labelling information that should accompany the accessible name property when presenting an object's content or identity to the end user. Similarly, ATSPI_RELATION_CONTROLLER_FOR can be used to further specify the context in which a valuator is useful, and/or the other UI components which are directly effected by user interactions with the valuator. Common examples include association of scrollbars with the viewport or panel which they control.

Enumeration used to specify the type of relation encapsulated in an #AtspiRelation object.

Index

Enumeration Members

CONTROLLED_BY: number

Object state, position, etc. is modified/controlled by user interaction with one or more other objects. For instance a viewport or scroll pane may be ATSPI_RELATION_CONTROLLED_BY scrollbars.

CONTROLLER_FOR: number

Object is an interactive object which modifies the state, onscreen location, or other attributes of one or more target objects.

DESCRIBED_BY: number

Reciprocal of %ATSPI_RELATION_DESCRIPTION_FOR. Indicates that one or more target objects provide descriptive information about this object. This relation type is most appropriate for information that is not essential as its presentation may be user-configurable and/or limited to an on-demand mechanism such as an assistive technology command. For brief, essential information such as can be found in a widget's on-screen label, use %ATSPI_RELATION_LABELLED_BY. For an on-screen error message, use %ATSPI_RELATION_ERROR_MESSAGE. For lengthy extended descriptive information contained in an on-screen object, consider using %ATSPI_RELATION_DETAILS as assistive technologies may provide a means for the user to navigate to objects containing detailed descriptions so that their content can be more closely reviewed.

DESCRIPTION_FOR: number

Reciprocal of %ATSPI_RELATION_DESCRIBED_BY. Indicates that this object provides descriptive information about the target object(s). See also %ATSPI_RELATION_DETAILS_FOR and %ATSPI_RELATION_ERROR_FOR.

DETAILS: number

Reciprocal of %ATSPI_RELATION_DETAILS_FOR. Indicates that this object has a detailed or extended description, the contents of which can be found in the target object(s). This relation type is most appropriate for information that is sufficiently lengthy as to make navigation to the container of that information desirable. For less verbose information suitable for announcement only, see %ATSPI_RELATION_DESCRIBED_BY. If the detailed information describes an error condition, %ATSPI_RELATION_ERROR_FOR should be used instead. Since: 2.26.

DETAILS_FOR: number

Reciprocal of %ATSPI_RELATION_DETAILS. Indicates that this object provides a detailed or extended description about the target object(s). See also %ATSPI_RELATION_DESCRIPTION_FOR and %ATSPI_RELATION_ERROR_FOR. Since: 2.26.

EMBEDDED_BY: number

Reciprocal of ATSPI_RELATION_EMBEDS. Used to denote content rendered by embedded renderers that live in a separate process space from the embedding context.

EMBEDS: number

Similar to ATSPI_RELATION_SUBWINDOW_OF, but specifically used for cross-process embedding.

ERROR_FOR: number

Reciprocal of %ATSPI_RELATION_ERROR_MESSAGE. Indicates that this object contains an error message describing an invalid condition in the target object(s). Since: 2.26.

ERROR_MESSAGE: number

Reciprocal of %ATSPI_RELATION_ERROR_FOR. Indicates that this object has one or more errors, the nature of which is described in the contents of the target object(s). Objects that have this relation type should also contain %ATSPI_STATE_INVALID_ENTRY in their #AtspiStateSet. Since: 2.26.

EXTENDED: number

Used to indicate that a relationship exists, but its type is not specified in the enumeration.

FLOWS_FROM: number

Reciprocal of ATSPI_RELATION_FLOWS_TO.

FLOWS_TO: number

Object renders content which flows logically to another object. For instance, text in a paragraph may flow to another object which is not the 'next sibling' in the accessibility hierarchy.

LABELLED_BY: number

Object is labelled by one or more other objects.

LABEL_FOR: number

Object is a label for one or more other objects.

LAST_DEFINED: number

Do not use as a parameter value, used to determine the size of the enumeration.

MEMBER_OF: number

Object has a grouping relationship (e.g. 'same group as') to one or more other objects.

NODE_CHILD_OF: number

Object is a child of the target.

NODE_PARENT_OF: number

Object is a parent of the target.

NULL: number

Not a meaningful relationship; clients should not normally encounter this #AtspiRelationType value.

PARENT_WINDOW_OF: number

This is the reciprocal relation to ATSPI_RELATION_POPUP_FOR.

POPUP_FOR: number

Denotes that the object is a transient window or frame associated with another onscreen object. Similar to ATSPI_TOOLTIP_FOR, but more general. Useful for windows which are technically toplevels but which, for one or more reasons, do not explicitly cause their associated window to lose 'window focus'. Creation of an ATSPI_ROLE_WINDOW object with the ATSPI_RELATION_POPUP_FOR relation usually requires some presentation action on the part of assistive technology clients, even though the previous toplevel ATSPI_ROLE_FRAME object may still be the active window.

SUBWINDOW_OF: number

Object is visually and semantically considered a subwindow of another object, even though it is not the object's child. Useful when dealing with embedded applications and other cases where the widget hierarchy does not map cleanly to the onscreen presentation.

TOOLTIP_FOR: number

Object is a tooltip associated with another object.
