[wxperl-users] Perl Sockets & wxSocket

[Graciliano M. P. \(V. Sites\) <gm...@vi...>]

Mattia,

I saw in the TODO of wxPerl the line:
  wxSocket* ?

Well, I had think "why wrappe wxSocket if Perl already have Sockets", until
try to use Perl Sockets with Wx.
Is just impossible to use them together, specially on Win32.

I try to make an app that open a socket and write in some TextCtrl each line
received in the socket AND send through the Socket lines writed in other
TextCtrl, making a Talk program.

The problems:

1* I can't read all the time the Socket, since it's from Perl, and we stop
the Wx app if we stay inside a loop on Perl subs. To avoid this I make the
program read the Socket from a wxTimer every 1s. But to never break Wx I
need to make first a IO::Select in the Socket, or we stop (freeze) until
receive data.

2* IO::Select doesn't work with Wx, at least on Win32!!! Yes, since
IO::Socket use a interface similar to sleep() to wait for the data, and
sleep() doesn't work when Wx is loaded on Win32, we can't make a IO::Select,
since it always say that the Socket doesn't have data in the buffer when Wx
is loaded!

3* Read a Socket from a Perl function can make some conflicts with other
events of Wx, since we are always running a Perl sub. Imagine if you want to
read 2+ Sockets!

4* If I want to read and send data through the Socket I really need to use
IO::Socket! Or I only can send data after read something!

The concept of Socket for GUI interface are different of Perl Sockets. I
think that  wxSocket will be useful, since we can work with events to get
connections and data. And the Accept(), like other functions, can be used
without block the GUI.
