I have been working through the Finger example section, and also use
wxPython for a GUI, and although it was a bit tricky to setup, it
works fine. I also setup my Finger server code as a .tac, and twistd
starts it up also. Here is some of the code fragments I used:
# finger_server.py
from twisted.python import log
from twisted.internet import wxreactor
wxreactor.install()
# import t.i.reactor only after installing wxreactor:
from twisted.application import internet, service
from twisted.internet import reactor, protocol, defer
from twisted.protocols import basic
The first step is importing *and* installing wxreactor. After that,
you have to create and register a wxPython App with the Reactor, and
it takes care of the wx loop.
app = MyApp(0)
reactor.registerWxApp(app)
msgWin = app.frame.foundText # this is a textCtrl I send output to.
fs = FingerService(msgWin)
ff = fs.getFingerFactory()
fsf = fs.getFingerSetterFactory()
global application
application = service.Application('finger', uid=1, gid=1)
sc = service.IServiceCollection(application)
internet.TCPServer(79, ff).setServiceParent(sc)
internet.TCPServer(179, fsf).setServiceParent(sc)
In my code, I actually use:
if __name__ == '__main__':
main_code()
else:
service_code()
This lets me run the code in Eclipse for testing, then I copy the .py
file to a .tac file, and it works as a twistd daemon, including
popping up a wxPython window for output. It *also* works as a
standalone file when I use py2exe on the .py file - but I don't see
how you could use twistd with a .exe, since twistd expects a script.
I hope this is clear - if not, I can send you my entire
finger_server.py file, for your amusement :)
