AtkRole

Describes the role of an object

These are the built-in enumerated roles that UI components can have in ATK. Other roles may be added at runtime, so an AtkRole >= ATK_ROLE_LAST_DEFINED is not necessarily an error.

FORM85

The object is a container for form controls, for instance as part of a web form or user-input form within a document.

The log contains a meaningful sequence and new information is added only to the end of the log, not at arbitrary points. @Since: ATK-2.12

MATH111

A text widget or container that holds a mathematical expression. @Since: ATK-2.12

RATING112

A widget whose purpose is to display a rating, such as the number of stars associated with a song in a media player. Objects of this role should also implement AtkValue. @Since: ATK-2.12

STATIC117

A generic non-container object whose purpose is to display a brief amount of information to the user and whose role is known by the implementor but lacks semantic value for the user. Examples in which ATK_ROLE_STATIC is appropriate include the message displayed in a message box and an image used as an alternative means to display text. ATK_ROLE_STATIC should not be applied to widgets which are traditionally interactive, objects which display a significant amount of content, or any object which has an accessible relation pointing to another object. Implementors should expose the displayed information through the accessible name of the object. If doing so seems inappropriate, it may indicate that a different role should be used. For labels which describe another widget, see ATK_ROLE_LABEL. For text views, see ATK_ROLE_TEXT. For generic containers, see ATK_ROLE_PANEL. For objects whose role is not known by the implementor, see ATK_ROLE_UNKNOWN. @Since: ATK-2.16.
