## Description

Actions are organised into groups. An action group is essentially a map from names to GtkAction 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.

## Details

### GtkActionGroup

    typedef struct _GtkActionGroup GtkActionGroup;

The GtkActionGroup struct contains only private members and should not be accessed directly.

### gtk_action_group_new ()

    GtkActionGroup* gtk_action_group_new        (const gchar *name);

Creates a new GtkActionGroup object. The name of the action group is used when associating keybindings with the actions.

`name` : | the name of the action group.
Returns : | the new GtkActionGroup

Since 2.4

### gtk_action_group_get_name ()

    const gchar* gtk_action_group_get_name      (GtkActionGroup *action_group);

Gets the name of the action group.

`action_group` : | the action group
Returns : | the name of the action group.

Since 2.4

### gtk_action_group_get_sensitive ()

    gboolean    gtk_action_group_get_sensitive  (GtkActionGroup *action_group);

Returns `TRUE` if the group is sensitive. The constituent actions can only be logically sensitive (see `gtk_action_is_sensitive()`) if they are sensitive (see `gtk_action_get_sensitive()`) and their group is sensitive.

`action_group` : | the action group
Returns : | `TRUE` if the group is sensitive.

Since 2.4

### gtk_action_group_set_sensitive ()

    void        gtk_action_group_set_sensitive  (GtkActionGroup *action_group,
                                                 gboolean sensitive);

Changes the sensitivity of `action_group`

`action_group` : | the action group
`sensitive` : | new sensitivity

Since 2.4

### gtk_action_group_get_visible ()

    gboolean    gtk_action_group_get_visible    (GtkActionGroup *action_group);

Returns `TRUE` if the group is visible. The constituent actions can only be logically visible (see `gtk_action_is_visible()`) if they are visible (see `gtk_action_get_visible()`) and their group is visible.

`action_group` : | the action group
Returns : | `TRUE` if the group is visible.

Since 2.4

### gtk_action_group_set_visible ()

    void        gtk_action_group_set_visible    (GtkActionGroup *action_group,
                                                 gboolean visible);

Changes the visible of `action_group`.

`action_group` : | the action group
`visible` : | new visiblity

Since 2.4

### gtk_action_group_get_action ()

    GtkAction*  gtk_action_group_get_action     (GtkActionGroup *action_group,
                                                 const gchar *action_name);

Looks up an action in the action group by name.

`action_group` : | the action group
`action_name` : | the name of the action
Returns : | the action, or `NULL` if no action by that name exists

Since 2.4

### gtk_action_group_list_actions ()

    GList*      gtk_action_group_list_actions   (GtkActionGroup *action_group);

Lists the actions in the action group.

`action_group` : | the action group
Returns : | an allocated list of the action objects in the action group

Since 2.4

### gtk_action_group_add_action ()

    void        gtk_action_group_add_action     (GtkActionGroup *action_group,
                                                 GtkAction *action);

Adds an action object to the action group. Note that this function does not set up the accel path of the action, which can lead to problems if a user tries to modify the accelerator of a menuitem associated with the action. Therefore you must either set the accel path yourself with `gtk_action_set_accel_path()`, or use `gtk_action_group_add_action_with_accel (..., NULL)`.

`action_group` : | the action group
`action` : | an action

Since 2.4

### gtk_action_group_add_action_with_accel ()

    void        gtk_action_group_add_action_with_accel
                                                (GtkActionGroup *action_group,
                                                 GtkAction *action,
                                                 const gchar *accelerator);

Adds an action object to the action group and sets up the accelerator.

If `accelerator` is `NULL`, attempts to use the accelerator associated with the stock_id of the action.

Accel paths are set to `<Actions>/`group-name`/`action-name``.

`action_group` : | the action group
`action` : | the action to add
`accelerator` : | the accelerator for the action, in the format understood by `gtk_accelerator_parse()`, or "" for no accelerator, or `NULL` to use the stock accelerator

Since 2.4

### gtk_action_group_remove_action ()

    void        gtk_action_group_remove_action  (GtkActionGroup *action_group,
                                                 GtkAction *action);

Removes an action object from the action group.

`action_group` : | the action group
`action` : | an action

Since 2.4

### GtkActionEntry

    typedef struct {
      const gchar     *name;
      const gchar     *stock_id;
      const gchar     *label;
      const gchar     *accelerator;
      const gchar     *tooltip;
      GCallback  callback;
    } GtkActionEntry;

GtkActionEntry structs are used with `gtk_action_group_add_actions()` to construct actions.

const gchar *`name`; | The name of the action.
const gchar *`stock_id`; | The stock id for the action, or the name of an icon from the icon theme.
const gchar *`label`; | The label for the action. This field should typically be marked for translation, see `gtk_action_group_set_translation_domain()`.
const gchar *`accelerator`; | The accelerator for the action, in the format understood by `gtk_accelerator_parse()`.
const gchar *`tooltip`; | The tooltip for the action. This field should typically be marked for translation, see `gtk_action_group_set_translation_domain()`.
GCallback `callback`; | The function to call when the action is activated.

### gtk_action_group_add_actions ()

    void        gtk_action_group_add_actions    (GtkActionGroup *action_group,
                                                 const GtkActionEntry *entries,
                                                 guint n_entries,
                                                 gpointer user_data);

This is a convenience function to create a number of actions and add them to the action group.

The "activate" signals of the actions are connected to the callbacks and their accel paths are set to `<Actions>/`group-name`/`action-name``.

`action_group` : | the action group
`entries` : | an array of action descriptions
`n_entries` : | the number of entries
`user_data` : | data to pass to the action callbacks

Since 2.4

### gtk_action_group_add_actions_full ()

    void        gtk_action_group_add_actions_full
                                                (GtkActionGroup *action_group,
                                                 const GtkActionEntry *entries,
                                                 guint n_entries,
                                                 gpointer user_data,
                                                 GDestroyNotify destroy);

This variant of `gtk_action_group_add_actions()` adds a GDestroyNotify callback for `user_data`.

`action_group` : | the action group
`entries` : | an array of action descriptions
`n_entries` : | the number of entries
`user_data` : | data to pass to the action callbacks
`destroy` : | destroy notification callback for `user_data`

Since 2.4

### GtkToggleActionEntry

    typedef struct {
      const gchar     *name;
      const gchar     *stock_id;
      const gchar     *label;
      const gchar     *accelerator;
      const gchar     *tooltip;
      GCallback  callback;
      gboolean   is_active;
    } GtkToggleActionEntry;

GtkToggleActionEntry structs are used with `gtk_action_group_add_toggle_actions()` to construct toggle actions.

const gchar *`name`; | The name of the action.
const gchar *`stock_id`; | The stock id for the action, or the name of an icon from the icon theme.
const gchar *`label`; | The label for the action. This field should typically be marked for translation, see `gtk_action_group_set_translation_domain()`.
const gchar *`accelerator`; | The accelerator for the action, in the format understood by `gtk_accelerator_parse()`.
const gchar *`tooltip`; | The tooltip for the action. This field should typically be marked for translation, see `gtk_action_group_set_translation_domain()`.
GCallback `callback`; | The function to call when the action is activated.
gboolean `is_active`; | The initial state of the toggle action.

### gtk_action_group_add_toggle_actions ()

    void        gtk_action_group_add_toggle_actions
                                                (GtkActionGroup *action_group,
                                                 const GtkToggleActionEntry *entries,

                                                 GDestroyNotify destroy);

This variant of `gtk_action_group_add_toggle_actions()` adds a GDestroyNotify callback for `user_data`.

`action_group` : | the action group
`entries` : | an array of toggle action descriptions
`n_entries` : | the number of entries
`user_data` : | data to pass to the action callbacks
`destroy` : | destroy notification callback for `user_data`

### GtkRadioActionEntry

    typedef struct {
      const gchar *name;
      const gchar *stock_id;
      const gchar *label;
      const gchar *accelerator;
      const gchar *tooltip;
      gint   value;
    } GtkRadioActionEntry;

GtkRadioActionEntry structs are used with `gtk_action_group_add_radio_actions()` to construct groups of radio actions.

const gchar *`name`; | The name of the action.
const gchar *`stock_id`; | The stock id for the action, or the name of an icon from the icon theme.
const gchar *`label`; | The label for the action. This field should typically be marked for translation, see `gtk_action_group_set_translation_domain()`.
const gchar *`accelerator`; | The accelerator for the action, in the format understood by `gtk_accelerator_parse()`.
const gchar *`tooltip`; | The tooltip for the action. This field should typically be marked for translation, see `gtk_action_group_set_translation_domain()`.
gint `value`; | The value to set on the radio action. See `gtk_radio_action_get_current_value()`.

### gtk_action_group_add_radio_actions ()

    void        gtk_action_group_add_radio_actions
                                                (GtkActionGroup *action_group,
                                                 const GtkRadioActionEntry *entries,
                                                 guint n_entries,
                                                 gint value,
                                                 GCallback on_change,
                                                 gpointer user_data);

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``.

`action_group` : | the action group
`entries` : | an array of radio action descriptions
`n_entries` : | the number of entries
`value` : | the value of the action to activate initially, or -1 if no action should be activated
`on_change` : | the callback to connect to the changed signal
`user_data` : | data to pass to the action callbacks

                                                 guint n_entries,
                                                 gint value,
                                                 GCallback on_change,

                                                 GDestroyNotify destroy);

This variant of `gtk_action_group_add_radio_actions()` adds a GDestroyNotify callback for `user_data`.

`action_group` : | the action group
`entries` : | an array of radio action descriptions
`n_entries` : | the number of entries
`value` : | the value of the action to activate initially, or -1 if no action should be activated
`on_change` : | the callback to connect to the changed signal
`user_data` : | data to pass to the action callbacks
`destroy` : | destroy notification callback for `user_data`

### gtk_action_group_set_translate_func ()

    void        gtk_action_group_set_translate_func
                                                (GtkActionGroup *action_group,
                                                 GtkTranslateFunc func,
                                                 gpointer data,
                                                 GtkDestroyNotify notify);

Sets a function to be used for translating the `label` and `tooltip` of GtkActionGroupEntrys added by `gtk_action_group_add_actions()`.

If you're using `gettext()`, it is enough to set the translation domain with `gtk_action_group_set_translation_domain()`.

`action_group` : | a GtkActionGroup
`func` : | a GtkTranslateFunc
`data` : | data to be passed to `func` and `notify`
`notify` : | a GtkDestroyNotify function to be called when `action_group` is destroyed and when the translation function is changed again

### gtk_action_group_set_translation_domain ()

    void        gtk_action_group_set_translation_domain
                                                (GtkActionGroup *action_group,
                                                 const gchar *domain);

Sets the translation domain and uses `dgettext()` for translating the `label` and `tooltip` of GtkActionEntrys added by `gtk_action_group_add_actions()`.

If you're not using `gettext()` for localization, see `gtk_action_group_set_translate_func()`.

`action_group` : | a GtkActionGroup
`domain` : | the translation domain to use for `dgettext()` calls

Since 2.4

### gtk_action_group_translate_string ()

    const gchar* gtk_action_group_translate_string
                                                (GtkActionGroup *action_group,
                                                 const gchar *string);

Translates a string using the specified `translate_func()`. This is mainly intended for language bindings.

`action_group` : | a GtkActionGroup
`string` : | a string
Returns : | the translation of `string`

Default value: NULL

### The "`sensitive`" property

      "sensitive"            gboolean              : Read / Write

Whether the action group is enabled.

Default value: TRUE

      "visible"              gboolean              : Read / Write

Whether the action group is visible.

Default value: TRUE

## Signal Details

### The "connect-proxy" signal

    void        user_function                  (GtkActionGroup *action_group,
                                                GtkAction      *action,
                                                GtkWidget      *proxy,
                                                gpointer        user_data)         :

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.

GtkUIManager proxies the signal and provides global notification just before any action is connected to a proxy, which is probably more convenient to use.

`action_group` : | the group
`action` : | the action
`proxy` : | the proxy
`user_data` : | user data set when the signal handler was connected.

Since 2.4

### The "disconnect-proxy" signal

    void        user_function                  (GtkActionGroup *action_group,
                                                GtkAction      *action,
                                                GtkWidget      *proxy,
                                                gpointer        user_data)         :

The disconnect_proxy signal is emitted after disconnecting a proxy from an action in the group.

GtkUIManager proxies the signal and provides global notification just before any action is connected to a proxy, which is probably more convenient to use.

`action_group` : | the group
`action` : | the action
`proxy` : | the proxy
`user_data` : | user data set when the signal handler was connected.

Since 2.4

### The "post-activate" signal

    void        user_function                  (GtkActionGroup *action_group,
                                                GtkAction      *action,
                                                gpointer        user_data)         :

The post_activate signal is emitted just after the `action` in the `action_group` is activated

This is intended for GtkUIManager to proxy the signal and provide global notification just after any action is activated.

`action_group` : | the group
`action` : | the action
`user_data` : | user data set when the signal handler was connected.

Since 2.4

### The "pre-activate" signal

    void        user_function                  (GtkActionGroup *action_group,
                                                GtkAction      *action,
                                                gpointer        user_data)         :

The pre_activate signal is emitted just before the `action` in the `action_group` is activated

This is intended for GtkUIManager to proxy the signal and provide global notification just before any action is activated.

`action_group` : | the group
`action` : | the action
`user_data` : | user data set when the signal handler was connected.
