[Pythoncard-users] twistedEchoClient sample

[Kevin A. <al...@se...>]

twistedEchoClient/

I've added a twistedModel.py module to the PythonCard framework package  
which contains a TwistedApplication class that can be used instead of  
Application (formerly PythonCardApp) if you want to write a PythonCard  
application that uses Twisted. The twistedEchoClient shows how to use  
the new class. I also created a generic loginDialog so it would be easy  
to connect to a server on another machine with a different default  
port, username, and password. Obviously this won't be available until  
release 0.8 unless you're working from PythonCard cvs.

Here's the readme.txt file:

Twisted Echo client which uses the TwistedApplication class.

class TwistedApplication(model.Application):
     def OnInit(self):
         model.Application.OnInit(self)
         reactor.startRunning()
         wx.EVT_TIMER(self, 999999, self.OnTimer)
         self.twistedTimer = wx.Timer(self, 999999)
         self.twistedTimer.Start(250, False)
         return True

     def OnTimer(self, event):
         reactor.iterate()

     def OnExit(self):
         # need to stop the timer for cleanup purposes
         self.twistedTimer.Stop()
         self.twistedTimer = None
         reactor.stop()


You need to start pbecho.py first so you have a server to connect to.  
pbecho.py is included in the Twisted distribution within your Python  
site-packages directory:

     site-packages/TwistedDocs/examples/pbecho.py
