ATSPI_Collection_MATCH_ALL | TRUE if all of the criteria are met. |
ATSPI_Collection_MATCH_ANY | TRUE if any of the criteria are met. |
ATSPI_Collection_MATCH_NONE | TRUE if none of the criteria are met. |
ATSPI_Collection_MATCH_EMPTY | Same as `ATSPI_Collection_MATCH_ALL` if the criteria is non-empty; for empty criteria this rule requires returned value to also have empty set. |

### ATSPI_TREETRAVERSALTYPE

    #define ATSPI_TREETRAVERSALTYPE _COUNT(3+1)

### enum AtspiComponentLayer

The AtspiComponentLayer of an AtspiComponent instance indicates its relative stacking order with respect to the onscreen visual representation of the UI. AtspiComponentLayer, in combination with AtspiComponent bounds information, can be used to compute the visibility of all or part of a component. This is important in programmatic determination of region-of-interest for magnification, and in flat screen review models of the screen, as well as for other uses. Objects residing in two of the AtspiComponentLayer categories support further z-ordering information, with respect to their peers in the same layer: namely, `ATSPI_LAYER_WINDOW` and `ATSPI_LAYER_MDI` . Relative stacking order for other objects within the same layer is not available; the recommended heuristic is first child paints first. In other words, assume that the first siblings in the child list are subject to being overpainted by later siblings if their bounds intersect. The order of layers, from bottom to top, is: `ATSPI_LAYER_BACKGROUND` , `ATSPI_LAYER_WINDOW` , `ATSPI_LAYER_MDI` , `ATSPI_LAYER_CANVAS` , `ATSPI_LAYER_WIDGET` , `ATSPI_LAYER_POPUP` , and `ATSPI_LAYER_OVERLAY` .

#### Members

ATSPI_LAYER_INVALID | Indicates an error condition or uninitialized value. |
ATSPI_LAYER_BACKGROUND | The bottom-most layer, over which everything else is painted. The 'desktop background' is generally in this layer. |
ATSPI_LAYER_CANVAS | The 'background' layer for most content renderers and UI AtspiComponent containers. |
ATSPI_LAYER_WIDGET | The layer in which the majority of ordinary 'foreground' widgets reside. |
ATSPI_LAYER_MDI | A special layer between `ATSPI_LAYER_CANVAS` and `ATSPI_LAYER_WIDGET` , in which the 'pseudo windows' (e.g. the MDI frames) reside. See atspi_component_get_mdi_z_order. |
ATSPI_LAYER_POPUP | A layer for popup window content, above `ATSPI_LAYER_WIDGET` . |
ATSPI_LAYER_OVERLAY | The topmost layer. |
ATSPI_LAYER_WINDOW | The layer in which a toplevel window background usually resides. |
ATSPI_LAYER_LAST_DEFINED | Used only to determine the end of the enumeration. |

### enum AtspiTextBoundaryType

Specifies the boundary conditions determining a run of text as returned from atspi_text_get_text_at_offset, atspi_text_get_text_after_offset, and atspi_text_get_text_before_offset.

This enumerationis deprecated since 2.9.90 and should not be used. Use AtspiTextGranularity with atspi_text_get_string_at_offset instead.

#### Members

ATSPI_TEXT_BOUNDARY_CHAR | An AtspiText instance is bounded by this character only. Start and end offsets differ by one, by definition, for this value. |
ATSPI_TEXT_BOUNDARY_WORD_START | Boundary condition is start of a word; i.e. range is from start of one word to the start of another word. |
ATSPI_TEXT_BOUNDARY_WORD_END | Boundary condition is the end of a word; i.e. range is from the end of one word to the end of another. Some locales may not distinguish between words and characters or glyphs. In particular, those locales which use wholly or partially ideographic character sets. In these cases, characters may be returned in lieu of multi-character substrings. |
ATSPI_TEXT_BOUNDARY_SENTENCE_START | Boundary condition is start of a sentence, as determined by the application. Some locales or character sets may not include explicit sentence delimiters, so this boundary type can not always be honored. Some locales will return lines of text instead of grammatical sentences. |
ATSPI_TEXT_BOUNDARY_SENTENCE_END | Boundary condition is end of a sentence, as determined by the application, including the sentence-delimiting character, for instance '.' Some locales or character sets may not include explicit sentence delimiters, so this boundary type can not always be honored. Some locales will return lines of text instead of grammatical sentences. |
ATSPI_TEXT_BOUNDARY_LINE_START | Boundary condition is the start of a line; i.e. range is from start of one line to the start of another. This generally means that an end-of-line character will appear at the end of the range. |
ATSPI_TEXT_BOUNDARY_LINE_END | Boundary condition is the end of a line; i.e. range is from start of one line to the start of another. This generally means that an end-of-line character will be the first character of the range. |

### enum AtspiTextClipType

Enumeration used by interface AtspiText to indicate how to treat characters intersecting bounding boxes.

#### Members

ATSPI_TEXT_CLIP_NONE | No characters/glyphs are omitted. |
ATSPI_TEXT_CLIP_MIN | Characters/glyphs clipped by the minimum coordinate are omitted. |
ATSPI_TEXT_CLIP_MAX | Characters/glyphs which intersect the maximum coordinate are omitted. |
ATSPI_TEXT_CLIP_BOTH | Only glyphs falling entirely within the region bounded by min and max are retained. |

### enum AtspiStateType

Enumeration used by various interfaces indicating every possible state an AtspiAccesible object can assume.

#### Members

ATSPI_STATE_INVALID | Indicates an invalid state - probably an error condition. |

ATSPI_STATE_ACTIVE

Indicates a window is currently the active window, or an object is the active subelement within a container or table. `ATSPI_STATE_ACTIVE` should not be used for objects which have `ATSPI_STATE_FOCUSABLE` or `ATSPI_STATE_SELECTABLE` : Those objects should use `ATSPI_STATE_FOCUSED` and `ATSPI_STATE_SELECTED` respectively. `ATSPI_STATE_ACTIVE` is a means to indicate that an object which is not focusable and not selectable is the currently-active item within its parent container.

ATSPI_STATE_ARMED | Indicates that the object is armed. |
ATSPI_STATE_BUSY | Indicates the current object is busy, i.e. onscreen representation is in the process of changing, or the object is temporarily unavailable for interaction due to activity already in progress. |
ATSPI_STATE_CHECKED | Indicates this object is currently checked. |
ATSPI_STATE_COLLAPSED | Indicates this object is collapsed. |
ATSPI_STATE_DEFUNCT | Indicates that this object no longer has a valid backing widget (for instance, if its peer object has been destroyed). |
ATSPI_STATE_EDITABLE | Indicates the user can change the contents of this object. |
ATSPI_STATE_ENABLED | Indicates that this object is enabled, i.e. that it currently reflects some application state. Objects that are "greyed out" may lack this state, and may lack the `ATSPI_STATE_SENSITIVE` if direct user interaction cannot cause them to acquire `ATSPI_STATE_ENABLED` . See `ATSPI_STATE_SENSITIVE` . |
ATSPI_STATE_EXPANDABLE | Indicates this object allows progressive disclosure of its children. |
ATSPI_STATE_EXPANDED | Indicates this object is expanded. |
ATSPI_STATE_FOCUSABLE | Indicates this object can accept keyboard focus, which means all events resulting from typing on the keyboard will normally be passed to it when it has focus. |
ATSPI_STATE_FOCUSED | Indicates this object currently has the keyboard focus. |
ATSPI_STATE_HAS_TOOLTIP | Indicates that the object has an associated tooltip. |
ATSPI_STATE_HORIZONTAL | Indicates the orientation of this object is horizontal. |
ATSPI_STATE_ICONIFIED | Indicates this object is minimized and is represented only by an icon. |
ATSPI_STATE_MODAL | Indicates something must be done with this object before the user can interact with an object in a different window. |
ATSPI_STATE_MULTI_LINE | Indicates this (text) object can contain multiple lines of text. |
ATSPI_STATE_MULTISELECTABLE | Indicates this object allows more than one of its children to be selected at the same time, or in the case of text objects, that the object supports non-contiguous text selections. |
ATSPI_STATE_OPAQUE | Indicates this object paints every pixel within its rectangular region. It also indicates an alpha value of unity, if it supports alpha blending. |
ATSPI_STATE_PRESSED | Indicates this object is currently pressed. |
ATSPI_STATE_RESIZABLE | Indicates the size of this object's size is not fixed. |
ATSPI_STATE_SELECTABLE | Indicates this object is the child of an object that allows its children to be selected and that this child is one of those children that can be selected. |
ATSPI_STATE_SELECTED | Indicates this object is the child of an object that allows its children to be selected and that this child is one of those children that has been selected. |

ATSPI_STATE_SENSITIVE

Indicates this object is sensitive, e.g. to user interaction. `ATSPI_STATE_SENSITIVE` usually accompanies. `ATSPI_STATE_ENABLED` for user-actionable controls, but may be found in the absence of `ATSPI_STATE_ENABLED` if the current visible state of the control is "disconnected" from the application state. In such cases, direct user interaction can often result in the object gaining `ATSPI_STATE_SENSITIVE` , for instance if a user makes an explicit selection using an object whose current state is ambiguous or undefined. See `ATSPI_STATE_ENABLED` , `ATSPI_STATE_INDETERMINATE` .

ATSPI_STATE_SHOWING | Indicates this object, the object's parent, the object's parent's parent, and so on, are all 'shown' to the end-user, i.e. subject to "exposure" if blocking or obscuring objects do not interpose between this object and the top of the window stack. |
ATSPI_STATE_SINGLE_LINE | Indicates this (text) object can contain only a single line of text. |
ATSPI_STATE_STALE | Indicates that the information returned for this object may no longer be synchronized with the application state. This can occur if the object has `ATSPI_STATE_TRANSIENT` , and can also occur towards the end of the object peer's lifecycle. |
ATSPI_STATE_TRANSIENT | Indicates this object is transient. |
ATSPI_STATE_VERTICAL | Indicates the orientation of this object is vertical; for example this state may appear on such objects as scrollbars, text objects (with vertical text flow), separators, etc. |

ATSPI_STATE_VISIBLE

Indicates this object is visible, e.g. has been explicitly marked for exposure to the user. `ATSPI_STATE_VISIBLE` is no guarantee that the object is actually unobscured on the screen, only that it is 'potentially' visible, barring obstruction, being scrolled or clipped out of the field of view, or having an ancestor container that has not yet made visible. A widget is potentially onscreen if it has both `ATSPI_STATE_VISIBLE` and `ATSPI_STATE_SHOWING` . The absence of `ATSPI_STATE_VISIBLE` and `ATSPI_STATE_SHOWING` is semantically equivalent to saying that an object is 'hidden'.

ATSPI_STATE_MANAGES_DESCENDANTS

Indicates that "active-descendant-changed" event is sent when children become 'active' (i.e. are selected or navigated to onscreen). Used to prevent need to enumerate all children in very large containers, like tables. The presence of `ATSPI_STATE_MANAGES_DESCENDANTS` is an indication to the client that the children should not, and need not, be enumerated by the client. Objects implementing this state are expected to provide relevant state notifications to listening clients, for instance notifications of visibility changes and activation of their contained child objects, without the client having previously requested references to those children.

ATSPI_STATE_INDETERMINATE

Indicates that a check box or other boolean indicator is in a state other than checked or not checked. This usually means that the boolean value reflected or controlled by the object does not apply consistently to the entire current context. For example, a checkbox for the "Bold" attribute of text may have `ATSPI_STATE_INDETERMINATE` if the currently selected text contains a mixture of weight attributes. In many cases interacting with a `ATSPI_STATE_INDETERMINATE` object will cause the context's corresponding boolean attribute to be homogenized, whereupon the object will lose `ATSPI_STATE_INDETERMINATE` and a corresponding state-changed event will be fired.

ATSPI_STATE_REQUIRED | Indicates that user interaction with this object is 'required' from the user, for instance before completing the processing of a form. |
ATSPI_STATE_TRUNCATED | Indicates that an object's onscreen content is truncated, e.g. a text value in a spreadsheet cell. |

ATSPI_STATE_ANIMATED

Indicates this object's visual representation is dynamic, not static. This state may be applied to an object during an animated 'effect' and be removed from the object once its visual representation becomes static. Some applications, notably content viewers, may not be able to detect all kinds of animated content. Therefore the absence of this state should not be taken as definitive evidence that the object's visual representation is static; this state is advisory.

ATSPI_STATE_INVALID_ENTRY | This object has indicated an error condition due to failure of input validation. For instance, a form control may acquire this state in response to invalid or malformed user input. |

ATSPI_STATE_SUPPORTS_AUTOCOMPLETION

This state indicates that the object in question implements some form of typeahead or pre-selection behavior whereby entering the first character of one or more sub-elements causes those elements to scroll into view or become selected. Subsequent character input may narrow the selection further as long as one or more sub-elements match the string. This state is normally only useful and encountered on objects that implement AtspiSelection. In some cases the typeahead behavior may result in full or partial completion of the data in the input field, in which case these input events may trigger text-changed events from the source.

ATSPI_STATE_SELECTABLE_TEXT

This state indicates that the object in question supports text selection. It should only be exposed on objects which implement the AtspiText interface, in order to distinguish this state from `ATSPI_STATE_SELECTABLE` , which infers that the object in question is a selectable child of an object which implements AtspiSelection. While similar, text selection and subelement selection are distinct operations.

ATSPI_STATE_IS_DEFAULT | This state indicates that the object in question is the 'default' interaction object in a dialog, i.e. the one that gets activated if the user presses "Enter" when the dialog is initially posted. |
ATSPI_STATE_VISITED | This state indicates that the object (typically a hyperlink) has already been activated or invoked, with the result that some backing data has been downloaded or rendered. |
ATSPI_STATE_CHECKABLE | Indicates this object has the potential to be checked, such as a checkbox or toggle-able table cell. `Since` : 2.12 |
ATSPI_STATE_HAS_POPUP | Indicates that the object has a popup context menu or sub-level menu which may or may not be showing. This means that activation renders conditional content. Note that ordinary tooltips are not considered popups in this context. `Since` : 2.12 |
ATSPI_STATE_READ_ONLY | Indicates that an object which is ENABLED and SENSITIVE has a value which can be read, but not modified, by the user. `Since` : 2.16 |
ATSPI_STATE_LAST_DEFINED | This value of the enumeration should not be used as a parameter, it indicates the number of items in the AtspiStateType enumeration. |

### enum AtspiKeyEventType

Deprecated. Should not be used.

#### Members

ATSPI_KEY_PRESSED |  |
ATSPI_KEY_RELEASED |  |

### enum AtspiEventType

Enumeration used to specify the event types of interest to an AtspiEventListener, or to identify the type of an event for which notification has been sent.

#### Members

ATSPI_KEY_PRESSED_EVENT | Indicates that a key on a keyboard device was pressed. |
ATSPI_KEY_RELEASED_EVENT | Indicates that a key on a keyboard device was released. |
ATSPI_BUTTON_PRESSED_EVENT | Indicates that a button on a non-keyboard human interface device (HID) was pressed. |
ATSPI_BUTTON_RELEASED_EVENT | Indicates that a button on a non-keyboard human interface device (HID) was released. |

### enum AtspiKeySynthType

Enumeration used when synthesizing keyboard input via atspi_generate_keyboard_event.

#### Members

ATSPI_KEY_PRESS | Emulates the pressing of a hardware keyboard key. |
ATSPI_KEY_RELEASE | Emulates the release of a hardware keyboard key. |
ATSPI_KEY_PRESSRELEASE | Emulates the pressing and immediate releasing of a hardware keyboard key. |

ATSPI_KEY_SYM

A symbolic key event is generated, without specifying a hardware key. Note: if the keysym is not present in the current keyboard map, the AtspiDeviceEventController instance has a limited ability to generate such keysyms on-the-fly. Reliability of GenerateKeyboardEvent calls using out-of-keymap keysyms will vary from system to system, and on the number of different out-of-keymap keysyms being generated in quick succession. In practice this is rarely significant, since the keysyms of interest to AT clients and keyboard emulators are usually part of the current keymap, i.e., present on the system keyboard for the current locale (even if a physical hardware keyboard is not connected).

ATSPI_KEY_STRING | A string is converted to its equivalent keyboard events and emitted. If the string consists of complex characters or composed characters which are not in the current keymap, string emission is subject to the out-of-keymap limitations described for `ATSPI_KEY_SYM` . In practice this limitation primarily effects Chinese and Japanese locales. |

### enum AtspiModifierType

#### Members

ATSPI_MODIFIER_SHIFT | The left or right 'Shift' key. |
ATSPI_MODIFIER_SHIFTLOCK | The ShiftLock or CapsLock key. |
ATSPI_MODIFIER_CONTROL | 'Control'/'Ctrl'. |
ATSPI_MODIFIER_ALT | The Alt key (as opposed to AltGr). |
ATSPI_MODIFIER_META | Depending on the platform, this may map to 'Window', 'Function', 'Meta', 'Menu', or 'NumLock'. Such 'Meta keys' will map to one of META, META2, META3. On X Windows platforms these META values map to the modifier masks Mod1Mask, Mod2Mask, Mod3Mask, e.g. an event having `ATSPI_MODIFIER_META2` means that the 'Mod2Mask' bit is set in the corresponding XEvent. |
ATSPI_MODIFIER_META2 | See `ATSPI_MODIFIER_META` . |
ATSPI_MODIFIER_META3 | See `ATSPI_MODIFIER_META` . |
ATSPI_MODIFIER_NUMLOCK | A symbolic meta key name that is mapped by AT-SPI to the appropriate META value, for the convenience of the client. |

### enum AtspiRelationType

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.

#### Members

ATSPI_RELATION_NULL | Not a meaningful relationship; clients should not normally encounter this AtspiRelationType value. |
ATSPI_RELATION_LABEL_FOR | Object is a label for one or more other objects. |
ATSPI_RELATION_LABELLED_BY | Object is labelled by one or more other objects. |
ATSPI_RELATION_CONTROLLER_FOR | Object is an interactive object which modifies the state, onscreen location, or other attributes of one or more target objects. |
ATSPI_RELATION_CONTROLLED_BY | 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. |
ATSPI_RELATION_MEMBER_OF | Object has a grouping relationship (e.g. 'same group as') to one or more other objects. |
ATSPI_RELATION_TOOLTIP_FOR | Object is a tooltip associated with another object. |
ATSPI_RELATION_NODE_CHILD_OF | Object is a child of the target. |
ATSPI_RELATION_NODE_PARENT_OF | Object is a parent of the target. |
ATSPI_RELATION_EXTENDED | Used to indicate that a relationship exists, but its type is not specified in the enumeration. |
ATSPI_RELATION_FLOWS_TO | 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. |
ATSPI_RELATION_FLOWS_FROM | Reciprocal of `ATSPI_RELATION_FLOWS_TO` . |
ATSPI_RELATION_SUBWINDOW_OF | 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. |
ATSPI_RELATION_EMBEDS | Similar to `ATSPI_RELATION_SUBWINDOW_OF` , but specifically used for cross-process embedding. |
ATSPI_RELATION_EMBEDDED_BY | Reciprocal of `ATSPI_RELATION_EMBEDS` . Used to denote content rendered by embedded renderers that live in a separate process space from the embedding context. |

ATSPI_RELATION_POPUP_FOR

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.

ATSPI_RELATION_PARENT_WINDOW_OF | This is the reciprocal relation to `ATSPI_RELATION_POPUP_FOR` . |
ATSPI_RELATION_DESCRIPTION_FOR | Indicates that an object provides descriptive information about another object; more verbose than `ATSPI_RELATION_LABEL_FOR` . |
ATSPI_RELATION_DESCRIBED_BY | Indicates that another object provides descriptive information about this object; more verbose than `ATSPI_RELATION_LABELLED_BY` . |
ATSPI_RELATION_LAST_DEFINED | Do not use as a parameter value, used to determine the size of the enumeration. |

### enum AtspiRole

ATSPI_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 `ATSPI_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 `ATSPI_ROLE_ENTRY` and `ATSPI_ROLE_PASSWORD_TEXT` . For generic objects which display a brief amount of textual information, see `ATSPI_ROLE_STATIC` .

ATSPI_ROLE_HEADER | An object that serves as a document header. |
ATSPI_ROLE_FOOTER | An object that serves as a document footer. |
ATSPI_ROLE_PARAGRAPH | An object which is contains a single paragraph of text content. See also `ATSPI_ROLE_TEXT` . |
ATSPI_ROLE_RULER | An object which describes margins and tab stops, etc. for text objects which it controls (should have `ATSPI_RELATION_CONTROLLER_FOR` relation to such). |
ATSPI_ROLE_APPLICATION | An object corresponding to the toplevel accessible of an application, which may contain `ATSPI_ROLE_FRAME` objects or other accessible objects. Children of AccessibleDesktop objects are generally `ATSPI_ROLE_APPLICATION` objects. |
ATSPI_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. |
ATSPI_ROLE_EDITBAR | The object is an editable text object in a toolbar. |
ATSPI_ROLE_EMBEDDED | The object is an embedded component container. This role is a "grouping" hint that the contained objects share a context which is different from the container in which this accessible is embedded. In particular, it is used for some kinds of document embedding, and for embedding of out-of-process component, "panel applets", etc. |
ATSPI_ROLE_ENTRY | The object is a component whose textual content may be entered or modified by the user, provided `ATSPI_STATE_EDITABLE` is present. A readonly `ATSPI_ROLE_ENTRY` object (i.e. where `ATSPI_STATE_EDITABLE` is not present) implies a read-only 'text field' in a form, as opposed to a title, label, or caption. |

ATSPI_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 `ATSPI_LABELLED_BY` relation is particularly important in interpreting objects of this type, as is the accessible description property. See `ATSPI_ROLE_CAPTION` .

ATSPI_ROLE_CAPTION | The object contains descriptive information, usually textual, about another user interface element such as a table, chart, or image. |

ATSPI_ROLE_DOCUMENT_FRAME

The object is a visual frame or container which contains a view of document content. AtspiDocument frames may occur within another AtspiDocument instance, in which case the second document may be said to be embedded in the containing instance. HTML frames are often ATSPI_ROLE_DOCUMENT_FRAME: Either this object, or a singleton descendant, should implement the AtspiDocument interface.

ATSPI_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. |
ATSPI_ROLE_PAGE | The object is a containing instance which encapsulates a page of information. `ATSPI_ROLE_PAGE` is used in documents and content which support a paginated navigation model. |
ATSPI_ROLE_SECTION | The object is a containing instance of document content which constitutes a particular 'logical' section of the document. The type of content within a section, and the nature of the section division itself, may be obtained by querying the object's attributes. Sections may be nested. |
ATSPI_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 be ignored by clients, if they are encountered at all. |

ATSPI_ROLE_FORM

The object is a containing instance of document content which has within it components with which the user can interact in order to input information; i.e. the object is a container for pushbuttons, comboboxes, text input fields, and other 'GUI' components. `ATSPI_ROLE_FORM` should not, in general, be used for toplevel GUI containers or dialogs, but should be reserved for 'GUI' containers which occur within document content, for instance within Web documents, presentations, or text documents. Unlike other GUI containers and dialogs which occur inside application instances, `ATSPI_ROLE_FORM` containers' components are associated with the current document, rather than the current foreground application or viewer instance.

ATSPI_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 AtspiHypertext/AtspiHyperlink interfacesto indicate the range/location within a text object where an inline or embedded object lies. |
ATSPI_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". |
ATSPI_ROLE_TABLE_ROW | A row in a table. |
ATSPI_ROLE_TREE_ITEM | An object that represents an element of a tree. |
ATSPI_ROLE_DOCUMENT_SPREADSHEET | A document frame which contains a spreadsheet. |

ATSPI_ROLE_GROUPING | A group of related widgets. This group typically has a label. |
ATSPI_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. |
ATSPI_ROLE_NOTIFICATION | A transitory object designed to present a message to the user, typically at the desktop level rather than inside a particular application. |
ATSPI_ROLE_INFO_BAR | An object designed to present a message to the user within an existing window. |
ATSPI_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: 2.8 |

ATSPI_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` : 2.12 |
ATSPI_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` : 2.12 |
ATSPI_ROLE_MATH | A text widget or container that holds a mathematical expression. `Since` : 2.12 |
ATSPI_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 AtspiValue. `Since` : 2.12 |
ATSPI_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` : 2.12 |

ATSPI_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 `ATSPI_ROLE_STATIC` is appropriate include the message displayed in a message box and an image used as an alternative means to display text. `ATSPI_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. The displayed information, as a general rule, should be exposed through the accessible name of the object. For labels which describe another widget, see `ATSPI_ROLE_LABEL` . For text views, see `ATSPI_ROLE_TEXT` . For generic containers, see `ATSPI_ROLE_PANEL` . For objects whose role is not known by the implementor, see `ATSPI_ROLE_UNKNOWN` . `Since` : 2.16.
