insert_action_group

Inserts group into this.

Children of this that implement [iface@Gtk.Actionable] can then be associated with actions in group by setting their “action-name” to prefix.`action-name`.

Note that inheritance is defined for individual actions. I.e. even if you insert a group with prefix prefix, actions with the same prefix will still be inherited from the parent, unless the group contains an action with the same name.

If group is null, a previously inserted group for name is removed from this.

Parameters:

this	a `GtkWidget`
name	the prefix for actions in group
group	a `GActionGroup`, or null to remove the previously inserted group for name
