Module: Atk::Action

Defined in:
(unknown)

Overview

Atk::Action should be implemented by instances of #AtkObject classes with which the user can interact directly, i.e. buttons, checkboxes, scrollbars, e.g. components which are not “passive” providers of UI information.

Exceptions: when the user interaction is already covered by another appropriate interface such as Atk::EditableText (insert/delete text, etc.) or Atk::Value (set value) then these actions should not be exposed by Atk::Action as well.

Though most UI interactions on components should be invocable via keyboard as well as mouse, there will generally be a close mapping between “mouse actions” that are possible on a component and the AtkActions. Where mouse and keyboard actions are redundant in effect, Atk::Action should expose only one action rather than exposing redundant actions if possible. By convention we have been using “mouse centric” terminology for Atk::Action names.

    the action index corresponding to the action to be performed

Returns:

  • (String) —

    a description string, or nil if action does

#get_keybinding(action, i) ⇒ String

this action, or nil if there is no keybinding for this action.

Parameters:

  • i (Integer) —

    the action index corresponding to the action to be performed

Returns:

  • (String) —

    a name string, or nil if action does not

#get_n_actions(action) ⇒ Integer

implement this interface.

Parameters:

Returns:

  • (String) —

    a name string, or nil if action does not

#n_actions ⇒ Integer

Gets the number of accessible actions available on the object. If there are more than one, the first one is considered the “default” action of the object. implement this interface.

Returns:

  • (Integer) —

    a the number of actions, or 0 if action does not

#set_description(action, i, desc) ⇒ TrueClass

Returns a gboolean representing if the description was successfully set;.
