NAME

Wx::Socket - wxSocket* classes

USAGE

use Wx qw(:socket) ;
use Wx::Event qw(EVT_SOCKET_INPUT EVT_SOCKET_LOST) ;
use Wx::Event qw(EVT_SOCKET_CONNECTION) ;

##########
# CLIENT #
##########

my $sock = Wx::SocketClient->new(wxSOCKET_WAITALL);

EVT_SOCKET_INPUT($parent , $sock , \&onInput ) ;
EVT_SOCKET_LOST($parent , $sock , \&onClose ) ;

$sock->Connect('localhost',5050) ;

if (! $sock->IsConnected ) { print "ERROR\n" ;}

sub onInput {
  my ( $sock , $this , $evt ) = @_ ;
  my $length = 123;
  my $buffer ;
  $sock->Read($buffer , 1024 , $length ) ;
}

##########
# SERVER #
##########

my $sock = Wx::SocketServer->new('localhost',5050,wxSOCKET_WAITALL);

EVT_SOCKET_CONNECTION($parent , $sock , \&onConnect ) ;

if ( !$sock->Ok ) { print "ERROR\n" ;}

sub onConnect {
  my ( $sock , $this , $evt ) = @_ ;
  my $client = $sock->Accept(0) ;

  my ($local_host,$local_port) = $client->GetLocal ;
  my ($peer_host,$peer_port) = $client->GetPeer ;

  $client->Write("This is a data test!\n") ;

... or ...

  $client->Write( $data , length($data) ) ;

  $client->Close ;
}

METHODS

All the methods work as in wxWidgets (see the documentation).

The functions for reading data (Read, ReadMsg, Peek) take 3 arguments, like the Perl read() function:

## To read the data into the variable
$sock->Read($buffer , 1024) ;

... or ...

## To append data at the given offset:
$sock->Read($buffer , 1024 , $offset ) ;

The write functions (Write, WriteMsg, Unread) can be used with 1 or 2 arguments:

$client->Write("This is a data test!\n") ;

$client->Write($data , $length) ;

EVENTS

The events are:

EVT_SOCKET
EVT_SOCKET_ALL
EVT_SOCKET_INPUT
EVT_SOCKET_OUTPUT
EVT_SOCKET_CONNECTION
EVT_SOCKET_LOST

The EVT_SOCKET works as in wxWidgets, the others are wxPerl extensions.

Note that EVT_SOCKET events of wxSocketClient and wxSocketServer work differently than other event types.

First you need to set the event handler:

$sock->SetEventHandler($handler, $id) ;

Then you set what types of event you want to receive:

## this select all.
$sock->SetNotify(wxSOCKET_INPUT_FLAG|wxSOCKET_OUTPUT_FLAG|
                 wxSOCKET_CONNECTION_FLAG|wxSOCKET_LOST_FLAG) ;

Enable the event notification:

$sock->Notify(1) ;

And only after this use:

## note that $handler must be the same that was used in
## SetEventHandler
EVT_SOCKET($handler, $id , sub{...} )

To make the events easier to use, all the proccess is automatic, and you just use:

EVT_SOCKET_INPUT($handler , $socket , sub{...} )
EVT_SOCKET_OUTPUT($handler , $socket , sub{...} )
EVT_SOCKET_CONNECTION($handler , $socket , sub{...} )
EVT_SOCKET_LOST($handler , $socket , sub{...} )

## This is for the events not used yet by the above:
EVT_SOCKET_ALL($parent , $socket , sub{...} )

** The new way is better to handle more than one socket in the same time too. Take a look in the demos.
