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.
