/**
 * A menu that divides its entries into submenus, alphabetically.  For
 * menus that may contain a very large or small number of named items
 * (e.g. plugins).
 *
 * The menu needs to be told, before any of the actions are added,
 * what the set of entry strings will be, so it can determine a
 * reasonable categorisation.  Do this by calling the setEntries()
 * method.  If it isn't practical to do this in advance, then add the
 * entries and call entriesAdded() afterwards instead.
