##### 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.
