reciprocal relations are set. See the GetRelationSet method.
-
An object usually contained in a menu to provide a

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.

otherwise clip a larger object or content renderer to a specific
onscreen viewport.
-
A top level window with no title or border.
-
means that the role for this item is known, but not
included in the core enumeration. Deprecated since 2.24.
-

-
An object that serves as a document footer.
-
An object which is contains a single paragraph of
text content. See also ATSPI_ROLE_TEXT.
-
An object which describes margins and tab stops, etc.
for text objects which it controls (should have
ATSPI_RELATION_CONTROLLER_FOR relation to such).
-
An object corresponding to the toplevel accessible
of an application, which may contain ATSPI_ROLE_FRAME objects or other
accessible objects. Children of objects with the ATSPI_ROLE_DESKTOP_FRAME role
are generally ATSPI_ROLE_APPLICATION objects.
-
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.
-
The object is an editable text object in a toolbar.
-
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.
-
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.
-
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.
-
The object contains descriptive information, usually
textual, about another user interface element such as a table, chart, or
image.
-
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
ATSPI_ROLE_DOCUMENT_FRAME: Either this object, or a singleton descendant,
should implement the org.a11y.atspi.Document interface.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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".
-
A row in a table.
-
An object that represents an element of a tree.
-
A document frame which contains a
spreadsheet.
-
A document frame which contains a
presentation or slide content.
-
A document frame which contains textual content,
such as found in a word processing application.
-
A document frame which contains HTML or other
markup suitable for display in a web browser.
-
A document frame which contains email content
to be displayed or composed either in plain text or HTML.
-
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.
-
A non-collapsible list of choices the user can select from.
-
A group of related widgets. This group typically has a label.
-
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.
-
A transitory object designed to present a
message to the user, typically at the desktop level rather than inside a
particular application.
-
An object designed to present a message to the user
within an existing window.
-
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
-

dialog. Since: 2.12
-
An object which contains a text section
that is quoted from another source. Since: 2.12
-

composition that forms an independent part of a document, page, or
site. Examples: A blog entry, a news story, a forum post. Since: 2.12
-
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: 2.12
-
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
-
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
-
A text widget or container that holds a mathematical
expression. Since: 2.12
-
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
the Value interface. Since: 2.12
-
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
-
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.
-
An object that represents a mathematical fraction. Since: 2.16.
-
An object that represents a mathematical expression
displayed with a radical. Since: 2.16.
-
An object that contains text that is displayed as a
subscript. Since: 2.16.
-
An object that contains text that is displayed as a
superscript. Since: 2.16.
-
An object that represents a list of term-value
groups. A term-value group represents an individual description and consist
of one or more names (ATSPI_ROLE_DESCRIPTION_TERM) followed by one or more
values (ATSPI_ROLE_DESCRIPTION_VALUE). For each list, there should not be
more than one group with the same term name. Since: 2.26.
-
An object that represents a term or phrase
with a corresponding definition. Since: 2.26.
-
An object that represents the description,
definition, or value of a term. Since: 2.26.
-
An object that contains the text of a footnote. Since: 2.26.
-
Content previously deleted or proposed to be
deleted, e.g. in revision history or a content view providing suggestions
from reviewers. Since: 2.34.
-
Content previously inserted or proposed to be
inserted, e.g. in revision history or a content view providing suggestions
from reviewers. Since: 2.34.
-
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 an ATSPI_RELATION_DETAILS relation should be used on the mark
to point to that associated section. In addition, the reciprocal relation
ATSPI_RELATION_DETAILS_FOR should be used on the associated content section
to point back to the mark. See the GetRelationSet method. Since: 2.36.
-
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. An object with this role should include children with
ATSPI_ROLE_CONTENT_DELETION and/or ATSPI_ROLE_CONTENT_INSERTION, in any order, to
indicate what the actual change is. Since: 2.36
-
A specialized push button to open a menu. Since: 2.46
-
Not a meaningful relationship; clients should not
normally encounter this value.
-
Object is a label for one or more other objects.
-
Object is labelled by one or more other
objects.
-
Object is an interactive object which
modifies the state, onscreen location, or other attributes of one or more
target objects.
-
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.
-
Object has a grouping relationship (e.g. 'same
group as') to one or more other objects.
-
Object is a tooltip associated with another
object.
-
Object is a child of the target.
-
Object is a parent of the target.
-
Used to indicate that a relationship exists, but
its type is not specified in the enumeration.
-
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.
-
Reciprocal of ATSPI_RELATION_FLOWS_TO.
-
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.
-
Similar to ATSPI_RELATION_SUBWINDOW_OF, but
specifically used for cross-process embedding.
-
Reciprocal of ATSPI_RELATION_EMBEDS. Used to
denote content rendered by embedded renderers that live in a separate process
space from the embedding context.
-
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.
-
This is the reciprocal relation to
ATSPI_RELATION_POPUP_FOR.
-
Reciprocal of ATSPI_RELATION_DESCRIBED_BY.
Indicates that this object provides descriptive information about the target
object(s). See also ATSPI_RELATION_DETAILS_FOR and ATSPI_RELATION_ERROR_FOR.
-
Reciprocal of ATSPI_RELATION_DESCRIPTION_FOR.
Indicates that one or more target objects provide descriptive information
about this object. This relation type is most appropriate for information
that is not essential as its presentation may be user-configurable and/or
limited to an on-demand mechanism such as an assistive technology command.
For brief, essential information such as can be found in a widget's on-screen
label, use ATSPI_RELATION_LABELLED_BY. For an on-screen error message, use
ATSPI_RELATION_ERROR_MESSAGE. For lengthy extended descriptive information
contained in an on-screen object, consider using ATSPI_RELATION_DETAILS as
assistive technologies may provide a means for the user to navigate to
objects containing detailed descriptions so that their content can be more
closely reviewed.
-
Reciprocal of ATSPI_RELATION_DETAILS_FOR. Indicates
that this object has a detailed or extended description, the contents of
which can be found in the target object(s). This relation type is most
appropriate for information that is sufficiently lengthy as to make
navigation to the container of that information desirable. For less verbose
information suitable for announcement only, see ATSPI_RELATION_DESCRIBED_BY.
If the detailed information describes an error condition,
ATSPI_RELATION_ERROR_FOR should be used instead. Since 2.26.
-
Reciprocal of ATSPI_RELATION_DETAILS. Indicates
that this object provides a detailed or extended description about the target
object(s). See also ATSPI_RELATION_DESCRIPTION_FOR and ATSPI_RELATION_ERROR_FOR.
Since 2.26.
-
Reciprocal of ATSPI_RELATION_ERROR_FOR.
Indicates that this object has one or more errors, the nature of which is
described in the contents of the target object(s). Objects that have this
relation type should also contain ATSPI_STATE_INVALID_ENTRY when their
GetState method is called. Since: 2.26.
-
Reciprocal of ATSPI_RELATION_ERROR_MESSAGE.
Indicates that this object contains an error message describing an invalid
condition in the target object(s). Since: 2.26.
-
Indicates an invalid state - probably an error
condition.
-
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.
-
Indicates that the object is armed.
-
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.
-
Indicates this object is currently checked.
-
Indicates this object is collapsed.
-
Indicates that this object no longer has a valid
backing widget (for instance, if its peer object has been destroyed).
-
Indicates the user can change the contents of this
object.
-
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.
-
Indicates this object allows progressive
disclosure of its children.
-
Indicates this object is expanded.
-
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.
-
Indicates this object currently has the keyboard
focus.
-
Indicates that the object has an associated
tooltip.
-
Indicates the orientation of this object is
horizontal.
-
Indicates this object is minimized and is
represented only by an icon.
-
Indicates something must be done with this object
before the user can interact with an object in a different window.
-
Indicates this (text) object can contain multiple
lines of text.
-
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.
-
Indicates this object paints every pixel within its
rectangular region. It also indicates an alpha value of unity, if it
supports alpha blending.
-
Indicates this object is currently pressed.
-
Indicates the size of this object's size is not
fixed.
-
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.
-
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.
-
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.
-
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.
-
Indicates this (text) object can contain only a
single line of text.
-
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.
-
Indicates this object is transient.
-
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.
-
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'.
-
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.
-
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.
-
Indicates that user interaction with this object is
'required' from the user, for instance before completing the
processing of a form.
-
Indicates that an object's onscreen content
is truncated, e.g. a text value in a spreadsheet cell.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
Indicates this object has the potential to
be checked, such as a checkbox or toggle-able table cell. Since: 2.12
-
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
-
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
