/**
*AtkRole:
*@ATK_ROLE_INVALID: Invalid role
*@ATK_ROLE_TABLE_ROW_HEADER: The header for a row of a table
*@ATK_ROLE_TEAR_OFF_MENU_ITEM: A menu item used to tear off and reattach its menu
*@ATK_ROLE_TERMINAL: An object that represents an accessible terminal. @Since: ATK-0.6
- *@ATK_ROLE_TEXT: An object that presents text to the user
+ *@ATK_ROLE_TEXT: An interactive widget that supports multiple lines of text and
+ * optionally accepts user input, but whose purpose is not to solicit user input.
+ * Thus ATK_ROLE_TEXT is appropriate for the text view in a plain text editor
+ * but inappropriate for an input field in a dialog box or web form. For widgets
+ * whose purpose is to solicit input from the user, see ATK_ROLE_ENTRY and
+ * ATK_ROLE_PASSWORD_TEXT. For generic objects which display a brief amount of
+ * textual information, see ATK_ROLE_STATIC.
*@ATK_ROLE_TOGGLE_BUTTON: A specialized push button that can be checked or unchecked, but does not provide a separate indicator for the current state
*@ATK_ROLE_TOOL_BAR: A bar or palette usually composed of push buttons or toggle buttons
*@ATK_ROLE_TOOL_TIP: An object that provides information about another object
*@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_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
