NAME

       Curses::Widgets::ProgressBar - Progress Bar Widgets

MODULE VERSION

       $Id: ProgressBar.pm,v 1.103 2002/11/03 23:40:04 corliss Exp corliss $

SYNOPSIS

	 use Curses::Widgets::ProgressBar;

	 $progress = Curses::Widgets::ProgessBar->({
	   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,
	   });

	 $progress->draw($mwh);

	 $progress->input(5);

	 See the Curses::Widgets pod for other methods.

REQUIREMENTS

       Curses
       Curses::Widgets

DESCRIPTION

       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.

METHODS

       new (inherited from Curses::Widgets)

	 $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 oth-
       ers 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.

       draw

	 $progress->draw($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.

       input

	 $progress->input(5);

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