/**
- * gtk_menu_new_from_model:
- * @model: a #GMenuModel
+ * gtk_menu_shell_bind_model:
+ * @menu_shell: a #GtkMenuShell
+ * @model: (allow-none): the #GMenuModel to bind to or %NULL to remove
+ * binding
+ * @action_namespace: (allow-none): the namespace for actions in @model
+ * @with_separators: %TRUE if toplevel items in @shell should have
+ * separators between them
+ *
+ * Establishes a binding between a #GtkMenuShell and a #GMenuModel.
+ *
+ * The contents of @shell are removed and then refilled with menu items
+ * according to @model. When @model changes, @shell is updated.
+ * Calling this function twice on @shell with different @model will
+ * cause the first binding to be replaced with a binding to the new
+ * model. If @model is %NULL then any previous binding is undone and
+ * all children are removed.
*
- * Creates a #GtkMenu and populates it with menu items and
- * submenus according to @model.
+ * @with_separators determines if toplevel items (eg: sections) have
+ * separators inserted between them. This is typically desired for
+ * menus but doesn't make sense for menubars.
*
- * The created menu items are connected to actions found in the
- * #GtkApplicationWindow to which the menu belongs - typically
- * by means of being attached to a widget (see gtk_menu_attach_to_widget())
- * that is contained within the #GtkApplicationWindows widget hierarchy.
+ * If @action_namespace is non-%NULL then the effect is as if all
+ * actions mentioned in the @model have their names prefixed with the
+ * namespace, plus a dot. For example, if the action "quit" is
+ * mentioned and @action_namespace is "app" then the effective action
+ * name is "app.quit".
*
- * Returns: a new #GtkMenu
+ * For most cases you are probably better off using
+ * gtk_menu_new_from_model() or gtk_menu_bar_new_from_model() or just
+ * directly passing the #GMenuModel to gtk_application_set_app_menu() or
+ * gtk_application_set_menu_bar().
*
