+ * @Short_description: A choice from multiple check menu items
+ * @Title: GtkRadioMenuItem
+ * @See_also: #GtkMenuItem, #GtkCheckMenuItem
+ *
+ * A radio menu item is a check menu item that belongs to a group. At each
+ * instant exactly one of the radio menu items from a group is selected.
+ *
+ * The group list does not need to be freed, as each #GtkRadioMenuItem will
+ * remove itself and its list item when it is destroyed.
+ *
+ * The correct way to create a group of radio menu items is approximatively
+ * this:
+ *
+ * <example>
+ * <title>How to create a group of radio menu items.</title>
+ * <programlisting>
+ * GSList *group = NULL;
+ * GtkWidget *item;
+ * gint i;
+ *
+ * for (i = 0; i < 5; i++)
+ * {
+ * item = gtk_radio_menu_item_new_with_label (group, "This is an example");
+ * group = gtk_radio_menu_item_get_group (GTK_RADIO_MENU_ITEM (item));
+ * if (i == 1)
+ * gtk_check_menu_item_set_active (GTK_CHECK_MENU_ITEM (item), TRUE);
+ * }
+ * </programlisting>
+ * </example>
