REQUIREMENTS

       Curses
       Curses::Widgets

DESCRIPTION

       Curses::Widgets::Calendar provides simplified OO access to Curses-based calendars.  Each
       object maintains it's own state information.

METHODS

   new (inherited from Curses::Widgets)
         $cal = Curses::Widgets::Calendar->({
           CAPTION     => 'Appointments',
           CAPTIONCOL  => 'yellow',
           INPUTFUNC   => \&scankey,
           FOREGROUND  => undef,
           BACKGROUND  => 'black',
           BORDER      => 1,
           BORDERCOL   => 'red',
           FOCUSSWITCH => "\t",
           X           => 1,
           Y           => 1,
           HIGHLIGHT   => [12, 17, 25],
           HIGHLIGHTCOL=> 'green',
           MONTH       => '11/2001',
           ONYEAR      => \&yearly,
           ONMONTH     => \&monthly,
           ONDAY       => \&daily,
           });

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

         Key         Default   Description
         ============================================================
         CAPTION       undef   Caption superimposed on border
         CAPTIONCOL    undef   Foreground colour for caption text
         INPUTFUNC \&scankey   Function to use to scan for keystrokes
         FOREGROUND    undef   Default foreground colour
         BACKGROUND    undef   Default background colour
         BORDER            1   Display a border around the field
         BORDERCOL     undef   Foreground colour for border
         FOCUSSWITCH    "\t"   Characters which signify end of input
         HIGHLIGHT        []   Days to highlight
         HIGHLIGHTCOL  undef   Default highlighted data colour
         HEADERCOL     undef   Default calendar header colour
         MONTH     (current)   Month to display
         VALUE             1   Day of the month where the cursor is
         ONYEAR        undef   Callback function triggered by year
         ONMONTH       undef   Callback function triggered by month
         ONDAY         undef   Callback function triggered by day

       Each of the ON* callback functions expect a subroutine reference that excepts one
       argument: a handle to the calendar object itself.  If more than one trigger is called, it
       will be called in the order of day, month, and then year.

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

       The draw method renders the calendar 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 calendar's selected day to be rendered in standout mode (inverse video).
