= class Gtk::ActionGroup
Actions are organised into groups. An action group is essentially a map from names to Gtk::Action objects. 

All actions that would make sense to use in a particular context should be in a single group. Multiple action groups may be used for a particular user interface. In fact, it is expected that most nontrivial applications will make use of multiple groups. For example, in an application that can edit multiple documents, one group holding global actions (e.g. quit, about, new), and one group per document holding actions that act on that document (eg. save, cut/copy/paste, etc). Each window's menus would be constructed from a combination of two action groups. 

Accelerators are handled by the GTK+ accelerator map. All actions are assigned an accelerator path (which normally has the form <Actions>/group-name/action-name) and a shortcut is associated with this accelerator path. All menuitems and toolitems take on this accelerator path. The GTK+ accelerator map code makes sure that the correct shortcut is displayed next to the menu item.

--- add_action(action, accelerator = nil)
    Adds an action object to the action group and sets up the accelerator.   ((* Since 2.4 *))
    If accelerator is nil, attempts to use the accelerator associated with the stock_id of the action.

    * action: a Gtk::Action  
    * Returns: self

--- add_actions(entries)
    This is a convenience method to create a number of actions and add them to the action group. 
    The "activate" signals of the actions are connected to the procs and their accel paths are set to <Actions>/group-name/action-name.  ((* Since 2.4 *))
    * entries: [[name, stock_id, label, tooltip, proc], ... ]: an array of action descriptions
       * name: The name of the action. 
       * stock_id: The stock id(the constant value of Gtk::Stock) for the action.

       * accelerator: The accelerator for the action, in the format understood by Gtk::Accelerator.parse.
       * tooltip: The tooltip for the action. This field should typically be marked for translation, see Gtk::ActionGroup#translation_domain=. 
       * proc: The proc object to call when the action is activated. The proc takes 2 parameters. 1st parameter is Gtk::ActionGroup, and 2nd one is Gtk::Action.

    * Returns: self

--- add_toggle_actions(entries)
    This is a convenience method to create a number of toggle actions and add them to the action group. 
    The "activate" signals of the actions are connected to the procs and their accel paths are set to <Actions>/group-name/action-name.  ((* Since 2.4 *))

       * is_active: The initial state of the toggle action.(true or false)
    * Returns: self

--- add_radio_actions(entries) {|action, current| ... }
    This is a convenience routine to create a group of radio actions and add them to the action group. 
    The "changed" signal of the first radio action is connected to the on_change callback and the accel paths of the actions are set to <Actions>/group-name/action-name.  ((* Since 2.4 *))
    * entries: [[name, stock_id, label, accelarator, tooltip, value], ... ]: an array of toggle action descriptions
       * name: The name of the action.

--- set_translate_func{|path| ... }
    Sets a method to be used for translating the label and tooltip of Gtk::ActionGroup entries added by Gtk::ActionGroup#add_actions. 
    If you're using Gettext, it is enough to set the translation domain with Gtk::ActionGroup#translation_domain=.  ((* Since 2.4 *))
    * {|path| ... }: a block to translate given path.
       * path: path for translation
    * Returns: self

--- translation_domain=(domain)
    Sets the translation domain and uses dgettext() for translating the label and tooltip of Gtk::Action entries added by Gtk::ActionGroup#add_actions. 
    If you're not using GetText for localization, see Gtk::ActionGroup#set_translate_func.  ((* Since 2.4 *))
    * domain: the translation domain to use for dgettext calls
    * Returns: domain

--- set_translation_domain(domain)
    Same as translation_domain=.  ((* Since 2.4 *))
    * domain: the translation domain to use for dgettext calls

== Properties
--- name: String (Read/Write)
    A name for the action group.  ((* Since 2.4 *))

--- sensitive: true or false (Read/Write)
    Whether the action group is enabled.  ((* Since 2.4 *))

--- visible: true or false (Read/Write)
    Whether the action group is visible.  ((* Since 2.4 *))

== Signals
--- connect-proxy: self, action, proxy
    The connect_proxy signal is emitted after connecting a proxy to an action in the group. Note that the proxy may have been connected to a different action before. 
    This is intended for simple customizations for which a custom action class would be too clumsy, e.g. showing tooltips for menuitems in the statusbar. 
    Gtk::UIManager proxies the signal and provides global notification just before any action is connected to a proxy, which is probably more convenient to use.  ((* Since 2.4 *))
     * self: the Gtk::ActionGroup  
     * action: the Gtk::Action  
     * proxy: the proxy(Gtk::Widget)

--- disconnect-proxy: self, action, proxy
    The disconnect_proxy signal is emitted after disconnecting a proxy from an action in the group. 
    Gtk::UIManager proxies the signal and provides global notification just before any action is connected to a proxy, which is probably more convenient to use.  ((* Since 2.4 *))
     * self: the Gtk::ActionGroup  
     * action: the Gtk::Action  
     * proxy: the proxy(Gtk::Widget)

--- post-activate: self, action
    The post_activate signal is emitted just after the action in the action_group is activated 
    This is intended for Gtk::UIManager to proxy the signal and provide global notification just after any action is activated.  ((* Since 2.4 *))
     * self: the Gtk::ActionGroup  
     * action: the Gtk::Action  

--- pre-activate: self, action
    The pre_activate signal is emitted just before the action in the action_group is activated 
    This is intended for Gtk::UIManager to proxy the signal and provide global notification just before any action is activated.  ((* Since 2.4 *))
     * self: the Gtk::ActionGroup  
     * action: the Gtk::Action
