Libraries:Gtk:Gtk:ActionGroup
Types
T
Inherits from:Actions are organised into groups. An action group is essentially a map from names to Gtk.Gtk.Action.T 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.
GtkActionGroup as GtkBuildable
The GtkActionGroup implementation of the GtkBuildable interface accepts GtkAction objects as <child> elements in UI definitions.
Note that it is probably more common to define actions and action groups in the code, since they are directly related to what the code can do.
The GtkActionGroup implementation of the GtkBuildable interface supports a custom <accelerator> element, which has attributes named key and modifiers and allows to specify accelerators. This is similar to the <accelerator> element of GtkWidget, the main difference is that it doesn't allow you to specify a signal.
Example 38. A GtkDialog UI definition fragment.

Functions
GetType() : Gtk.GObject.Type.T
New(name @ Std.String.T) : Gtk.Gtk.ActionGroup.T
Creates a new T 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 T |
Methods
:AddAction(self @ T, action @ Gtk.Gtk.Action.T) : Std.Object.T
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.Gtk.Action.SetAccelPath, or use gtk_action_group_add_action_with_accel (..., NULL).
action_group | the action group |
action | an action |
:AddActionWithAccel(self @ T, action @ Gtk.Gtk.Action.T, accelerator @ Std.String.T) : Std.Object.T
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.Gtk.Accelerator.Parse, or "" for no accelerator, or NULL to use the stock accelerator. [allow-none] |
:AddActions(self @ T, entries @ Gtk.Gtk.ActionEntry.T, n_entries @ Std.Integer.SmallT, user_data) : Std.Object.T
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 |
:AddActionsFull(self @ T, entries @ Gtk.Gtk.ActionEntry.T, n_entries @ Std.Integer.SmallT, user_data, destroy @ Std.Function.T) : Std.Object.T
This variant of AddActions 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 |
:AddRadioActions(self @ T, entries @ Gtk.Gtk.RadioActionEntry.T, n_entries @ Std.Integer.SmallT, value @ Std.Integer.SmallT, on_change @ Std.Object.T, user_data) : Std.Object.T
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 |
:AddRadioActionsFull(self @ T, entries @ Gtk.Gtk.RadioActionEntry.T, n_entries @ Std.Integer.SmallT, value @ Std.Integer.SmallT, on_change @ Std.Object.T, user_data, destroy @ Std.Function.T) : Std.Object.T
This variant of AddRadioActions 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 |
:AddToggleActions(self @ T, entries @ Gtk.Gtk.ToggleActionEntry.T, n_entries @ Std.Integer.SmallT, user_data) : Std.Object.T
This is a convenience function to create a number of toggle 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 toggle action descriptions |
n_entries | the number of entries |
user_data | data to pass to the action callbacks |
:AddToggleActionsFull(self @ T, entries @ Gtk.Gtk.ToggleActionEntry.T, n_entries @ Std.Integer.SmallT, user_data, destroy @ Std.Function.T) : Std.Object.T
This variant of AddToggleActions 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 |
:GetAction(self @ T, action_name @ Std.String.T) : Gtk.Gtk.Action.T
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. [transfer none] |
:GetName(self @ T) : Std.String.T
Gets the name of the action group.
action_group | the action group |
Returns | the name of the action group. |
:GetSensitive(self @ T) : Std.Symbol.T

action_group | the action group |
Returns | TRUE if the group is sensitive. |
:GetVisible(self @ T) : Std.Symbol.T
Returns TRUE if the group is visible. The constituent actions can only be logically visible (see Gtk.Gtk.Action.IsVisible) if they are visible (see Gtk.Gtk.Action.GetVisible) and their group is visible.
action_group | the action group |
Returns | TRUE if the group is visible. |
:ListActions(self @ T) : Std.Object.T
Lists the actions in the action group.
action_group | the action group |

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

Sets the translation domain and uses g_dgettext() for translating the label and tooltip of Gtk.Gtk.ActionEntry.Ts added by AddActions.
If you're not using gettext() for localization, see SetTranslateFunc.
