use Curses::UI;
    my $cui = new Curses::UI;
    my $win = $cui->add('window_id', 'Window');

# The hard way.
    # -------------
    my $dialog = $win->add(
        'mydialog', 'Dialog::Error',
    -message   => 'The world has gone!'
    );
    $dialog->focus;
    $win->delete('mydialog');

# The easy way (see Curses::UI documentation).
    # --------------------------------------------
    $cui->error(-message => 'The world has gone!');

# or even:
    $cui->error('The world has gone!');

=head1 DESCRIPTION

Curses::UI::Dialog::Error is a basic error dialog. It is
almost the same as L<Curses::UI::Dialog::Basic|Curses::UI::Dialog::Basic>,
except for the fact that a warning sign is drawn to the left of
the message using ASCII "art":

_
      / \
     / ! \
    /_____\

Since this class is very closely related to the basic dialog,
see L<Curses::UI::Dialog::Basic|Curses::UI::Dialog::Basic> for
a description of the options and methods that you can use.
