    VALUE       => 0,
    INPUTFUNC   => \&scankey,
    FOREGROUND  => 'white',

  See the Curses::Widgets pod for other methods.

Curses::Widgets

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

  $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.

  $btns->draw($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).
