Curses::Widgets::ProgressBar - Progress Bar Widgets

  use Curses::Widgets::ProgressBar;

  $progress = Curses::Widgets::ProgessBar->({
    CAPTION     => 'Progress',
    CAPTIONCOL  => 'yellow',
    LENGTH      => 10,
    VALUE       => 0,
    FOREGROUND  => undef,

    HORIZONTAL  => 1,

  $progress->draw($mwh);

  $progress->input(5);

  See the Curses::Widgets pod for other methods.

Curses
Curses::Widgets

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

Note that this widget is designed for rendering, not interactive input. The application should update the the value of the bar by either calling the input method, which will add the passed value to the widget's current value, or by setting the value directly via the setField method.

  $progress = Curses::Widgets::ProgressBar->({
    CAPTION     => 'Progress',
    CAPTIONCOL  => 'yellow',
    LENGTH      => 10,
    VALUE       => 0,
    FOREGROUND  => undef,
    BACKGROUND  => 'black',
    BORDER      => 1,
    BORDERCOL   => undef,
    HORIZONTAL  => 1,
    X           => 1,
    Y           => 1,
    MIN         => 0,
    MAX         => 100,
    });

The new method instantiates a new Progress Bar 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
  LENGTH           10   Number of columns for the bar
  VALUE             0   Current value
  FOREGROUND    undef   Default foreground colour
  BACKGROUND    undef   Default blackground colour
  BORDER            1   Display border around the set
  BORDERCOL     undef   Foreground colour for border
  HORIZONTAL        1   Horizontal orientation for bar
  MIN               0   Low value for bar (0%)
  MAX             100   High vlaue for bar (100%)

Setting the value will change the length of the bar, based on the bounds set with MIN and MAX. The CAPTION is only rendered on the border of a horizontal progress bar.

  $progress->draw($mwh);

The draw method renders the progress bar in its current state. This requires a valid handle to a curses window in which it will render itself.

  $progress->input(5);

The argument is added to the progress bar's current value.
