Instance methods
atspi_accessible_clear_cache
Clears the cached information for the given accessible and all of its descendants.
atspi_accessible_get_accessible_id
Gets the accessible id of the accessible. This is not meant to be presented to the user, but to be an id which is stable over application development. Typically, this is the gtkbuilder id.
since: 2.34
atspi_accessible_get_atspi_version
Gets the AT-SPI IPC specification version supported by the application
pointed to by the AtspiAccessible object.
Only works on application root objects.
atspi_accessible_get_attributes
Gets the AttributeSet representing any assigned
name-value pair attributes or annotations for this object.
For typographic, textual, or textually-semantic attributes, see
atspi_text_get_attributes instead.
atspi_accessible_get_attributes_as_array
Gets a GArray representing any assigned
name-value pair attributes or annotations for this object.
For typographic, textual, or textually-semantic attributes, see
atspi_text_get_attributes_as_array instead.

atspi_accessible_get_interfaces
A set of pointers to all interfaces supported by an AtspiAccessible.
atspi_accessible_get_localized_role_name
Gets a UTF-8 string corresponding to the name of the role played by an object, translated to the current locale. This method will return useful values for roles that fall outside the enumeration used in atspi_accessible_getRole ().
atspi_accessible_get_process_id
Returns the process id associated with the given accessible. Mainly added for debugging; it is a shortcut to explicitly querying the accessible’s app->bus_name and then calling GetConnectionUnixProcessID.
atspi_accessible_get_relation_set
Gets the set of AtspiRelation objects which describes this AtspiAccessible object’s
relationships with other AtspiAccessible objects.

Only works on application root objects.
atspi_accessible_set_cache_mask
Sets the type of data to cache for accessibles. If this is not set for an application or is reset to ATSPI_CACHE_UNDEFINED, then the desktop’s cache flag will be used. If the desktop’s cache flag is also undefined, then all possible data will be cached. This function is intended to work around bugs in toolkits where the proper events are not raised / to aid in testing for such bugs.
Methods inherited from AtspiAction (8)
atspi_action_do_action
Invoke the action indicated by #index.
atspi_action_get_action_description
Get the description of ‘i-th’ action invocable on an
object implementing AtspiAction.
atspi_action_get_action_name
Get the name of the ‘i-th’ action invocable on an
object implementing AtspiAction.
atspi_action_get_description
Get the description of ‘i-th’ action invocable on an
object implementing AtspiAction.
deprecated: 2.10
atspi_action_get_key_binding
Get the keybindings for the i-th action invocable on an
object implementing AtspiAction, if any are defined.
The keybindings string format is as follows:
there are multiple parts to a keybinding string (typically 3).
They are delimited with “;”. The first is the action’s
keybinding which is usable if the object implementing the action
is currently posted to the screen, e.g. if a menu is posted
then these keybindings for the corresponding menu-items are
available. The second keybinding substring is the full key sequence
necessary to post the action’s widget and activate it, e.g. for
a menu item such as “File->Open” it would both post the menu and
activate the item. Thus the second keybinding string is available
during the lifetime of the containing toplevel window as a whole,
whereas the first keybinding string only works while the object
implementing AtkAction is posted. The third (and optional)
keybinding string is the “keyboard shortcut” which invokes the
action without posting any menus.
Meta-keys are indicated by the conventional strings
“<Control>”, “<Alt>”, “<Shift>”, “<Mod2>”,
etc. (we use the same string as gtk_accelerator_name() in gtk+-2.X.
atspi_action_get_localized_name

Signals
Atspi.Accessible::region-changed

Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
