REQUIREMENTS ^

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).

HISTORY ^

1999/12/29 -- Original calendar widget in functional model
