00038 class MenuItem(object):
    This is the base class for a definition of a menu item. Consider this
    "abstract" (in the language of Java) - it makes no sense to instantiate it
    directly. If you want to define a new kind of menu item, you need to
    subclass it like so:
    class MenuPerformMagic:
        identifier = "RabbitVCS::Perform_Magic"
        label = _("Perform Magic")
        tooltip = _("Put on your robe and wizard hat")
        icon = "rabbitvcs-wand" # or, say, gtk.STOCK_OPEN
    There is some introspection magic that goes on to associate the items
    themselves with certain methods of a ContextMenuCondition object or a
    ContextMenuCallback object. This is done by looking at the identifier - the
    part of the identifier after "::" is converted to lowercase and the item
    looks for a method of that name (eg. in the example above,
    It is easy to override this, just define condition_name and callback_name
    to be what you need. If the item cannot find anything, it defaults to not
    assigning the callback and having the condition return False.
    There a few ways to organise this (and maybe it would be better to have the
    GtkContextMenu class do it), but this is it for the moment.
