IO::LCDproc (3pm)

        use IO::LCDproc;

        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 );
        $client->connect() or die "cannot connect: $!";
        $client->initialize();

        $title->set( data => "This is the title" );
        $first->set( data => "First Line" );
        $second->set( data => "Second line" );
        $third->set( data => "Third Line" );

        $client->flushAnswers();

Follow the example above. Pretty straight forward. You create a client, assign a screen, add widgets, and then set the widgets.

IO::LCDproc::Client

It is the back engine of the module. It generates the connection to a ready listening server.

\s-1METHODS\s0 Constructor. Takes the following possible arguments (arguments must be given in key => value form): host, port, and name. name is required.

add( \s-1SCREENREF\s0 )

Adds the screens that will be attached to this client.

connect()

Establishes connection to LCDproc server (LCDd).

initialize()

Initializes client, screen and all the widgets with the server.

answer()

Reads an answer from the server

flushAnswers()

Flushes all answers from the server (should be called regulary if you don't need the answers)

IO::LCDproc::Screen

\s-1METHODS\s0

new( name => '\s-1MYNAME\s0')

Constructor. Allowed options: heartbeat => 1 or 0. Adds the given widgets to this screen. Sets the screen priority with $prio one of

hidden The screen will never be visible background The screen is only visible when no normal info screens exists info normal info screen, default priority foreground an active client alert The screen has an important message for the user. input The client is doing interactive input.

\s-1METHODS\s0

new( name => '\s-1MYNAME\s0' )

Constructor. Allowed arguments: align (left, center, rigth), type (string, title, vbar, hbar, ...), xPos, yPos, data

set()
