         See the Curses::Widgets pod for other methods.

REQUIREMENTS

       Curses
       Curses::Widgets

DESCRIPTION

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

METHODS

   new (inherited from Curses::Widgets)
         $btns = Curses::Widgets::ButtonSet->({
           LENGTH      => 10,
           VALUE       => 0,
           INPUTFUNC   => \&scankey,
           FOREGROUND  => 'white',
           BACKGROUND  => 'black',
           BORDER      => 1,
           BORDERCOL   => 'red',
           FOCUSSWITCH => "\t\n",
           HORIZONTAL  => 1,
           PADDING     => 1,
           X           => 1,
           Y           => 1,
           LABELS      => [qw(OK CANCEL)],
           });

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

         Key         Default    Description
         ============================================================
         LENGTH             10  Number of columns for each button label
         VALUE               0  Button selected (0-based indexing)
         INPUTFUNC   \&scankey  Function to use to scan for keystrokes
         FOREGROUND      undef  Default foreground colour
         BACKGROUND      undef  Default blackground colour
         BORDER              1  Display border around the set
         BORDERCOL       undef  Foreground colour for border
         FOCUSSWITCH    "\t\n"  Characters which signify end of input
         HORIZONTAL          1  Horizontal orientation for set
         PADDING             1  Number of spaces between buttons

       The last option, PADDING, is only applicable to horizontal sets without borders.

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

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

HISTORY

       1999/12/29 -- Original button set widget in functional model
