133 * always have ATK_ROLE_FORM. @Since: ATK-1.12.0
134 *@ATK_ROLE_LINK: The object is a hypertext anchor, i.e. a "link" in a
135 * hypertext document. Such objects are distinct from 'inline'

138 * an inline or embedded object lies. @Since: ATK-1.12.1
139 *@ATK_ROLE_INPUT_METHOD_WINDOW: The object is a window or similar viewport
140 * which is used to allow composition or input of a 'complex character',

150 *@ATK_ROLE_LIST_BOX: A non-collapsible list of choices the user can select from. @Since: ATK-2.1.0
151 *@ATK_ROLE_GROUPING: A group of related widgets. This group typically has a label. @Since: ATK-2.1.0
152 *@ATK_ROLE_IMAGE_MAP: An image map object. Usually a graphic with multiple hotspots, where each hotspot can be activated resulting in the loading of another document or section of a document. @Since: ATK-2.1.0

164 * Describes the role of an object
166 * These are the built-in enumerated roles that UI components can have in
167 * ATK. Other roles may be added at runtime, so an AtkRole >=
168 * ATK_ROLE_LAST_DEFINED is not necessarily an error.
