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>/
)
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.

The GtkActionGroup struct contains only private members and should not be accessed directly.
GtkActionGroup* gtk_action_group_new (constgchar *name);
Creates a new GtkActionGroup object. The name of the action group is used when associating keybindings with the actions.

is sensitive.

) and their group
is visible.

Since 2.4
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)
.

::connect-proxy
signalvoid 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.

user_data : |
