NAME
UI::Dialog::Backend::CDialog - backend for the console dialog(1) variant.
SYNOPSIS
use UI::Dialog::Backend::CDialog;
my $d = new UI::Dialog::Backend::CDialog ( backtitle => 'Demo',
title => 'Default' );
$d->msgbox( title => 'Welcome!', text => 'Welcome one and all!' );
ABSTRACT
UI::Dialog::Backend::CDialog is the UI::Dialog backend for the console dialog variant. While this module
is used through UI::Dialog or any other loader module only the compatible methods are ever accessible.
However, when using this module directly in your application (as in the SYNOPSIS example) you are given
access to all the options and features of the real dialog(1) application.
DESCRIPTION
There are essentially two versions of the console dialog program. One has support for colours as well as
extra widgets, while the other does not have either. You can read about the colour support in the TEXT
MARKUP section.

DESCRIPTION
End the meter bar widget process. One of the flaws with gdialog is that the gauge widget does
not close properly and requies the end user to close the gauge window when 100% has been
reached. This is the second reason why I'm glad gdialog is going the way of the dodo.
RETURNS
