insert_action_group

Inserts an action group into the widget's actions.

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 widget
name	the prefix for actions in group
group	an action group
