use Curses::UI;

# The hard way.
# -------------
my $dialog = $win->add(

$win->delete('mydialog');
# The easy way (see Curses::UI documentation).

# or even:
$cui->status( 'Some message' );
$cui->nostatus;
=head1 DESCRIPTION
Curses::UI::Dialog::Status is not really a dialog, since
the user has no way of interacting with it. It is merely
a way of presenting status information to the user of
your program.
See exampes/demo-Curses::UI::Dialog::Status in the
distribution for a short demo.
=head1 OPTIONS
=over 4
=item * B<-title> < TEXT >
Set the title of the dialog window to TEXT.
=item * B<-message> < TEXT >
This option sets the initial message to show to TEXT.
=back
=head1 METHODS
=over 4
=item * B<new> ( OPTIONS )
=item * B<layout> ( )
=item * B<draw> ( BOOLEAN )
These are standard methods. See L<Curses::UI::Container|Curses::UI::Container>
for an explanation of these.
=item * B<message> ( TEXT )
This method will update the message of the status dialog
to TEXT. For this update to show, you will have to call the
B<draw> method of the progress dialog.
