The root accessible of + *any application's ATK hierarchy should have ATK_ROLE_APPLICATION. @Since: + *ATK-1.1.4 + *@ATK_ROLE_AUTOCOMPLETE: The object is a dialog or list containing items for + *insertion into an entry widget, for instance a list of words for completion of + *a text entry. @Since: ATK-1.3 + *@ATK_ROLE_EDITBAR: The object is an editable text object in a toolbar. @Since: + *ATK-1.5 + *@ATK_ROLE_EMBEDDED: The object is an embedded container within a document or + *panel. This role is a grouping "hint" indicating that the contained objects + *share a context. @Since: ATK-1.7.2 + *@ATK_ROLE_ENTRY: The object is a component whose textual content may be + *entered or modified by the user, provided @ATK_STATE_EDITABLE is present. + *@Since: ATK-1.11 + *@ATK_ROLE_CHART: The object is a graphical depiction of quantitative data. It + *may contain multiple subelements whose attributes and/or description may be + *queried to obtain both the quantitative data and information about how the + *data is being presented. The LABELLED_BY relation is particularly important in + *interpreting objects of this type, as is the accessible-description property. + *@Since: ATK-1.11 + *@ATK_ROLE_CAPTION: The object contains descriptive information, usually + *textual, about another user interface element such as a table, chart, or + *image. @Since: ATK-1.11 + *@ATK_ROLE_DOCUMENT_FRAME: The object is a visual frame or container which + *contains a view of document content. Document frames may occur within another + *Document instance, in which case the second document may be said to be + *embedded in the containing instance. HTML frames are often + *ROLE_DOCUMENT_FRAME. Either this object, or a singleton descendant, should + *implement the Document interface. @Since: ATK-1.11 + *@ATK_ROLE_HEADING: The object serves as a heading for content which follows it + *in a document. The 'heading level' of the heading, if availabe, may be + *obtained by querying the object's attributes. + *@ATK_ROLE_PAGE: The object is a containing instance which encapsulates a page + *of information. @ATK_ROLE_PAGE is used in documents and content which support + *a paginated navigation model. @Since: ATK-1.11 + *@ATK_ROLE_SECTION: The object is a containing instance of document content + *which constitutes a particular 'logical' section of the document.

Sections may be nested. + *@Since: ATK-1.11 + *@ATK_ROLE_REDUNDANT_OBJECT: The object is redundant with another object in the + *hierarchy, and is exposed for purely technical reasons. Objects of this role + *should normally be ignored by clients. @Since: ATK-1.11 + *@ATK_ROLE_FORM: The object is a container for form controls, for instance as + *part of a web form or user-input form within a document. This role is + *primarily a tag/convenience for clients when navigating complex documents, it + *is not expected that ordinary GUI containers will always have ATK_ROLE_FORM. + *@Since: ATK-1.12.0 + *@ATK_ROLE_LINK: The object is a hypertext anchor, i.e. a "link" in a + * hypertext document. Such objects are distinct from 'inline' + * content which may also use the Hypertext/Hyperlink interfaces + * to indicate the range/location within a text object where + * an inline or embedded object lies. @Since: ATK-1.12.1 + *@ATK_ROLE_INPUT_METHOD_WINDOW: The object is a window or similar viewport + * which is used to allow composition or input of a 'complex character', + * in other words it is an "input method window." @Since: ATK-1.12.1 + *@ATK_ROLE_TABLE_ROW: A row in a table. @Since: ATK-2.1.0 + *@ATK_ROLE_TREE_ITEM: An object that represents an element of a tree. @Since: + *ATK-2.1.0 + *@ATK_ROLE_DOCUMENT_SPREADSHEET: A document frame which contains a spreadsheet. + *@Since: ATK-2.1.0 + *@ATK_ROLE_DOCUMENT_PRESENTATION: A document frame which contains a + *presentation or slide content. @Since: ATK-2.1.0 + *@ATK_ROLE_DOCUMENT_TEXT: A document frame which contains textual content, such + *as found in a word processing application. @Since: ATK-2.1.0 + *@ATK_ROLE_DOCUMENT_WEB: A document frame which contains HTML or other markup + *suitable for display in a web browser. @Since: ATK-2.1.0 + *@ATK_ROLE_DOCUMENT_EMAIL: A document frame which contains email content to be + *displayed or composed either in plain text or HTML. @Since: ATK-2.1.0 + *@ATK_ROLE_COMMENT: An object found within a document and designed to present a + *comment, note, or other annotation. In some cases, this object might not be + *visible until activated. @Since: ATK-2.1.0 + *@ATK_ROLE_LIST_BOX: A non-collapsible list of choices the user can select + *from. @Since: ATK-2.1.0 + *@ATK_ROLE_GROUPING: A group of related widgets. This group typically has a + *label. @Since: ATK-2.1.0 + *@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 + *@ATK_ROLE_NOTIFICATION: A transitory object designed to present a message to + *the user, typically at the desktop level rather than inside a particular + *application. @Since: ATK-2.1.0 + *@ATK_ROLE_INFO_BAR: An object designed to present a message to the user within + *an existing window. @Since: ATK-2.1.0 + *@ATK_ROLE_LEVEL_BAR: A bar that serves as a level indicator to, for instance, + *show the strength of a password or the state of a battery. @Since: ATK-2.7.3 + *@ATK_ROLE_TITLE_BAR: A bar that serves as the title of a window or a + * dialog. @Since: ATK-2.12 + *@ATK_ROLE_BLOCK_QUOTE: An object which contains a text section + * that is quoted from another source. @Since: ATK-2.12 + *@ATK_ROLE_AUDIO: An object which represents an audio element. @Since: ATK-2.12 + *@ATK_ROLE_VIDEO: An object which represents a video element. @Since: ATK-2.12 + *@ATK_ROLE_DEFINITION: A definition of a term or concept. @Since: ATK-2.12 + *@ATK_ROLE_ARTICLE: A section of a page that consists of a + * composition that forms an independent part of a document, page, or + * site. Examples: A blog entry, a news story, a forum post. @Since: + * ATK-2.12 + *@ATK_ROLE_LANDMARK: A region of a web page intended as a + * navigational landmark. This is designed to allow Assistive + * Technologies to provide quick navigation among key regions within a + * document. @Since: ATK-2.12 + *@ATK_ROLE_LOG: A text widget or container holding log content, such + * as chat history and error logs. In this role there is a + * relationship between the arrival of new items in the log and the + * reading order. 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 + *@ATK_ROLE_MARQUEE: A container where non-essential information + * changes frequently. Common usages of marquee include stock tickers + * and ad banners. The primary difference between a marquee and a log + * is that logs usually have a meaningful order or sequence of + * important content changes. @Since: ATK-2.12 + *@ATK_ROLE_MATH: A text widget or container that holds a mathematical + * expression. @Since: ATK-2.12 + *@ATK_ROLE_RATING: 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 + *@ATK_ROLE_TIMER: An object containing a numerical counter which + * indicates an amount of elapsed time from a start point, or the time + * remaining until an end point. @Since: ATK-2.12 + *@ATK_ROLE_DESCRIPTION_LIST: An object that represents a list of + * term-value groups. A term-value group represents a individual + * description and consist of one or more names + * (ATK_ROLE_DESCRIPTION_TERM) followed by one or more values + * (ATK_ROLE_DESCRIPTION_VALUE). For each list, there should not be + * more than one group with the same term name. @Since: ATK-2.12 + *@ATK_ROLE_DESCRIPTION_TERM: An object that represents the term, or + * name, part of a term-description group in a description + * list. @Since: ATK-2.12 + *@ATK_ROLE_DESCRIPTION_VALUE: An object that represents the + * description, definition or value of a term-description group in a + * description list. The values within a group are alternatives, + * meaning that you can have several ATK_ROLE_DESCRIPTION_VALUE for a + * given ATK_ROLE_DESCRIPTION_TERM. @Since: ATK-2.12 + *@ATK_ROLE_STATIC: 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. + *@ATK_ROLE_MATH_FRACTION: An object that represents a mathematical fraction. + * @Since: ATK-2.16. + *@ATK_ROLE_MATH_ROOT: An object that represents a mathematical expression + * displayed with a radical. @Since: ATK-2.16. + *@ATK_ROLE_SUBSCRIPT: An object that contains text that is displayed as a + * subscript. @Since: ATK-2.16. + *@ATK_ROLE_SUPERSCRIPT: An object that contains text that is displayed as a + * superscript. @Since: ATK-2.16. + *@ATK_ROLE_FOOTNOTE: An object that contains the text of a footnote. @Since: + *ATK-2.26. + *@ATK_ROLE_CONTENT_DELETION: Content previously deleted or proposed to be + * deleted, e.g. in revision history or a content view providing suggestions + * from reviewers. (Since: 2.34) + *@ATK_ROLE_CONTENT_INSERTION: Content previously inserted or proposed to be + * inserted, e.g. in revision history or a content view providing suggestions + * from reviewers. (Since: 2.34) + *@ATK_ROLE_MARK: A run of content that is marked or highlighted, such as for + * reference purposes, or to call it out as having a special purpose. If the + * marked content has an associated section in the document elaborating on the + * reason for the mark, then %ATK_RELATION_DETAILS should be used on the mark + * to point to that associated section. In addition, the reciprocal relation + * %ATK_RELATION_DETAILS_FOR should be used on the associated content section + * to point back to the mark. (Since: 2.36) + *@ATK_ROLE_SUGGESTION: A container for content that is called out as a proposed + * change from the current version of the document, such as by a reviewer of the + * content. This role should include either %ATK_ROLE_CONTENT_DELETION and/or + * %ATK_ROLE_CONTENT_INSERTION children, in any order, to indicate what the + * actual change is. (Since: 2.36) + *@ATK_ROLE_LAST_DEFINED: not a valid role, used for finding end of the + *enumeration + * + * Describes the role of an object + * + * These are the built-in enumerated roles that UI components can have in + * ATK.
