REQUIREMENTS

       Curses
       Curses::Widgets
       Curses::Widgets::ListBox

DESCRIPTION

       Curses::Widgets::Menu provides simplified OO access to menus.  Each item in a menu can be
       tied to a subroutine reference which is called when selected.

METHODS

   new (inherited from Curses::Widgets)
         $menu = Curses::Widgets::Menu->new({
           INPUTFUNC   => \&scankey,
           FOREGROUND  => undef,
           BACKGROUND  => 'black',
           FOCUSSWITCH => "\t",
           MENUS       => {
             MENUORDER => [qw(File)],
             File      => {
               ITEMORDER => [qw(Save Quit)],
               Save      => \&Save,
               Quit      => \&Quit,
             },
           CURSORPOS   => 'File',
           BORDER      => 1,
           });

       The new method instantiates a new Menu object.  The only mandatory key/value pairs in the
       configuration hash are X and Y.  All others have the following defaults:

         Key           Default  Description
         ============================================================
         INPUTFUNC   \&scankey  Function to use to scan for keystrokes
         FOREGROUND      undef  Default foreground colour
         BACKGROUND    'black'  Default background colour
         FOCUSSWITCH      "\t"  Characters which signify end of input
         MENUS              {}  Menu structure
         CURSORPOS          ''  Current position of the cursor
         BORDER              0  Avoid window borders

       The MENUS option is a hash of hashes, with each hash a separate menu, and the constituent
       hashes being a Entry/Function pairs.  Each hash requires a special key/value pair that
       determines the order of the items when displayed.  Each item is separated by two spaces.

   draw
         $menu->draw($mwh, 1);

       The draw method renders the menu in its current state.  This requires a valid handle to a
       curses window in which it will render itself.  The optional second argument, if true, will
       cause the selection cursor to be rendered as well.

   popup
         $menu->popup;

       This method causes the menu to be displayed.  Since, theoretically, the menu should never
       be seen unless it's being actively used, we will always assume that we need to draw a
       cursor on the list as well.

   execute
         $menu->execute;

       This method acts like the standard Curses::Widgets method of the same name, with the
       exception being that selection of any menu item will also cause it to exit (having already
       called the associated item subroutine).
