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
" ;}

	 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
" ;}

	 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!
") ;

       ... 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!
") ;

	 $client->Write($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.
