REQUIREMENTS

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.
