Mac(3p)

NAME
Tk::ProgressBar::Mac - a blue, 3-D Macintosh Classic progress bar.

SYNOPSIS
 use Tk::ProgressBar::Mac;
 $pb = $parent->ProgressBar(-option => value);

DESCRIPTION
This widget provides a dynamic image that looks just like a Mac OS 9 progress bar. Packed around it are four Frames, north, south, east and west, within which you can stuff additional widgets. For example, see how Tk::Copy::Mac uses several Labels and a CollapsableFrame widget to create a reasonable facsimile of a Macintosh copy dialog.

The following option/value pairs are supported:

-width
    The maximun width of the Progressbar.

METHODS

reset
    Resets the progress bar image so that it appears unused (a $pb->set(0) still shows the bar's base and end cap).

set($percent)
    Sets the width of the progress bar, as a percentage of -width.

ADVERTISED WIDGETS
Component subwidgets can be accessed via the Subwidget method. Valid subwidget names are listed below.
