	       my $client      = IO::LCDproc::Client->new(name => "MYNAME");
	       my $screen      = IO::LCDproc::Screen->new(name => "screen");
	       my $title       = IO::LCDproc::Widget->new(
			       name => "date", type => "title"
			       );
	       my $first       = IO::LCDproc::Widget->new(
			       name => "first", align => "center", xPos => 1, yPos => 2
			       );
	       my $second      = IO::LCDproc::Widget->new(
			       name => "second", align => "center", xPos => 1, yPos => 3
			       );
	       my $third       = IO::LCDproc::Widget->new(
			       name => "third", xPos => 1, yPos => 4
			       );
	       $client->add( $screen );
	       $screen->add( $title, $first, $second, $third );
