USAGE

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

43         sub onConnect {
44           my ( $sock , $this , $evt ) = @_ ;
45           my $client = $sock->Accept(0) ;
46
47           my ($local_host,$local_port) = $client->GetLocal ;
48           my ($peer_host,$peer_port) = $client->GetPeer ;
49
50           $client->Write("This is a data test!\n") ;
51
52       ... or ...
53
54           $client->Write( $data , length($data) ) ;
55
56           $client->Close ;
57         }
58

METHODS

60       All the methods work as in wxWidgets (see the documentation).
61
62       The functions for reading data (Read, ReadMsg, Peek) take 3 arguments,
63       like the Perl read() function:
64
65         ## To read the data into the variable
66         $sock->Read($buffer , 1024) ;
67
68       ... or ...
69
70         ## To append data at the given offset:
71         $sock->Read($buffer , 1024 , $offset ) ;
72
73       The write functions (Write, WriteMsg, Unread) can be used with 1 or 2
74       arguments:
75
76         $client->Write("This is a data test!\n") ;
77
78         $client->Write($data , $length) ;
79

EVENTS

81       The events are:
82
83           EVT_SOCKET
84           EVT_SOCKET_ALL
85           EVT_SOCKET_INPUT
86           EVT_SOCKET_OUTPUT
87           EVT_SOCKET_CONNECTION
88           EVT_SOCKET_LOST
89
90       The EVT_SOCKET works as in wxWidgets, the others are wxPerl extensions.
91
92       Note that EVT_SOCKET events of wxSocketClient and wxSocketServer work
93       differently than other event types.
94
95       First you need to set the event handler:
96
97           $sock->SetEventHandler($handler, $id) ;
98
99       Then you set what types of event you want to receive:
100
101           ## this select all.
102           $sock->SetNotify(wxSOCKET_INPUT_FLAG|wxSOCKET_OUTPUT_FLAG|
103                            wxSOCKET_CONNECTION_FLAG|wxSOCKET_LOST_FLAG) ;
104
105       Enable the event notification:
106
107           $sock->Notify(1) ;
108
109       And only after this use:
110
111           ## note that $handler must be the same that was used in
112           ## SetEventHandler
113           EVT_SOCKET($handler, $id , sub{...} )
114
115       To make the events easier to use, all the proccess is automatic, and
116       you just use:
117
118           EVT_SOCKET_INPUT($handler , $socket , sub{...} )
119           EVT_SOCKET_OUTPUT($handler , $socket , sub{...} )
120           EVT_SOCKET_CONNECTION($handler , $socket , sub{...} )
121           EVT_SOCKET_LOST($handler , $socket , sub{...} )
122
123           ## This is for the events not used yet by the above:
124           EVT_SOCKET_ALL($parent , $socket , sub{...} )
125
126       ** The new way is better to handle more than one socket in the same
127       time too.
128          Take a look in the demos.
