Problem with wxSocket

I'm trying to play with wxSocket, but have strange results. The
fragment of code which I attached works perfectly well when run from
wxluaedit.exe (2.8.7.0-MSW-bin) but hangs after displaying the first
message ("connect: true") when run from any other tool (wxlua,
wxluafreeze, also embedded using wxluafreeze).

Could you please help me?
Thanks,
Mateusz Czaplinski

That is strange, what happens if you add a menu item (see minimal
sample or even a button) so that you have to click it before
connecting. I just tried it in Linux and you code works fine for all
three programs. Maybe it's a MSW thing with initializing?

wxLua and wxLuaFreeze, like typical C++ apps, run the Lua code to
create the GUI in the wxApp::OnInit() function which is called before
the mainloop is run. I wonder if this is why wxSocket works in
wxLuaEdit and not the others.

Let me know

You're right, it worked when made to run from an event handler of a
button - thanks a lot! It appears it never occured to me to think
about when the Lua code is actually run... and what you write about
that sounds possible, so maybe my problem was because some things in
Wx were not properly initialized yet during this OnInit() method.
And then, if I still want to connect immediately after starting the
program, I suppose I should probably look for some timer or something
similar (sounding like SwingUtils.invokeLater() ;)
