=head1 ABSTRACT

UI::Dialog::Gauged is simply another meta-class for UI::Dialog. This
class simply has a different order of priority than UI::Dialog and only
uses backends that support a standard set of gauge related functions.

=head1 DESCRIPTION

This class is simply a nice way to try and ensure a GNOME based widget set.

=head2 gauge_stop( )

=over 4

=item EXAMPLE

=over 6

 $d->gauge_stop();

=back

=item DESCRIPTION

=over 6

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.

=back

=item RETURNS

=over 6

TRUE (1) if the widget closed fine and FALSE (0) for anything else.
