Does anyone know how to use twisted and tkinter. I have a simple tcp
server
and I want to send messages to it once connected using a tkinter
button? I
have built the code as far as I can but don't know what to do from
here. Any reference I try to put to sendmessage in chatfactory doesn't
seem to work, just brings up error messages.
This is my code:
from twisted.interne t import reactor
from twisted.interne t.protocol import Protocol, ClientFactory
from twisted.protoco ls.basic import LineReceiver
from Tkinter import *
from twisted.interne t import tksupport
class ChatClient(Line Receiver):
def connectionMade( self):
self.sendLine(" Hello server")
def lineReceived(se lf, line):
pass
def connectionLost( self, reason):
pass
class ChatFactory(Cli entFactory):
protocol = ChatClient
def clientConnectio nFailed(self, connector, reason):
reactor.stop()
def clientConnectio nLost(self, connector, reason):
reactor.stop()
def sendMessage(sel f):
self.sendLine(" Test")
root = Tk()
b1 = Button(root,tex t="Send")
#b1.configure(c ommand=sendline to server here)
b1.pack()
tksupport.insta ll(root)
reactor.connect TCP('localhost' ,4567,ChatFacto ry())
reactor.run() 9 3430
Posting that error message would be helpful
Sorry. The error message is normally AttributeError: 'NoneType' object
has no attribute 'sendLine'" jo************@ gmail.com wrote: Posting that error message would be helpful

Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python24\li b\lib-tk\Tkinter.py", line 1345, in __call__
return self.func(*args )
TypeError: unbound method sendMessage() must be called with ChatFactory
instance
as first argument (got nothing instead)
I have simplified the code as well, now attached below:
from twisted.interne t import reactor
from twisted.interne t.protocol import Protocol, ClientFactory
from twisted.protoco ls.basic import LineReceiver
from Tkinter import *
from twisted.interne t import tksupport
class ChatClient(Line Receiver):
def connectionMade( self):
self.sendLine(" Hello server")
def lineReceived(se lf, line):
print line
def connectionLost( self, reason):
pass
class ChatFactory(Cli entFactory):
protocol = ChatClient
def clientConnectio nFailed(self, connector, reason):
reactor.stop()
def clientConnectio nLost(self, connector, reason):
reactor.stop()
def sendMessage(sel f):
self.sendLine(" Test")
root = Tk()
b1 = Button(root,tex t="Send")
b1.configure(co mmand=ChatFacto ry.sendMessage)
b1.pack()
tksupport.insta ll(root)
reactor.connect TCP('localhost' ,8886,ChatFacto ry())
reactor.run()

that's another error message, of course...
class ChatFactory(Cli entFactory):
protocol = ChatClient
def clientConnectio nFailed(self, connector, reason): reactor.stop()
def clientConnectio nLost(self, connector, reason): reactor.stop()
def sendMessage(sel f): self.sendLine(" Test")
root = Tk() b1 = Button(root,tex t="Send") b1.configure(co mmand=ChatFacto ry.sendMessage)
umm. what is that line supposed to do ?
if the purpose is to call the sendMessage method of the Chat-
Message instance you're passing to connectTCP, it's probably
better to create the instance first:
chat = ChatFactory()
root = Tk()
b1 = Button(root,tex t="Send")
b1.configure(co mmand=chat.send Message)
b1.pack()
tksupport.insta ll(root)
reactor.connect TCP('localhost' ,8886,chat)
reactor.run()
</F>
it now comes up with the error message
Traceback (most recent call last):
File "C:\Python24\li b\lib-tk\Tkinter.py", line 1345, in __call__
return self.func(*args )
File "C:\Documen ts and Settings\chris\ Desktop\Python\ client.py", line
30, in sendMessage
self.sendLine(" Test")
AttributeError: ChatFactory instance has no attribute 'sendLine'
"Chris" <ce******@gmail .com> skrev i meddelandet news:11******** **************@ g10g2000cwb.goo glegroups.com.. . it now comes up with the error message

Which is exactly what one would expect from this method
def sendMessage(sel f):
self.sendLine(" Test")
if the class you inherit from doesn't provide a sendLine method.
But since you wrote that method, what did you expect it to do ?
(If this is code from some Twisted manual or sample, it's probably time
to double-check your code against the source...)
</F>
There is no manual that's the problem. The sendLine method is part of
LineReceiver which is part of twisted. It's used to send a message over
the transport link. I can get it working by overriding twisted's
methods for example linereceived() or connectionmade( ). But how do I
get it to send a message over the transport to the server by clicking a
tkinter button? There are no examples or documents on the internet that
can help, I've searched for hours.
Fredrik is right, ChatFactory doesn't have sendLine as a method b/c it
doesn't inherit it from ClientFactory. The code: protocol = ChatClient
does do anything within ChatFactory except set the variable. Try out
these.
from twisted.protoco ls.basic import LineReceiver, LineReceiver.se ndLine
or change class ChatFactory(Cli entFactory) --- to:
class ChatFactory(Cli entFactory, LineReceiver):
or tell ChatFactory that sendLine comes from LineReceiver --
class ChatFactory(Cli entFactory):
protocol = ChatClient
def clientConnectio nFailed(self, connector, reason):
reactor.stop()
def clientConnectio nLost(self, connector, reason):
reactor.stop()
def sendMessage(sel f):
self.LineReceiv er.sendLine("Te st")
I'm pretty sure that those should work. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Hello,
I am very interested in fooling around with Twisted Matrix's HTTP Web

traditional CGI scripts?
After looking how asynchronous Twisted's framework really is, I have
been interested in it.
Thanks,

Hi,
Sorry for reposting but I changed my code and received a new error
message so I thought I would try it on the group again. I have a

connects to the server and sends messages. However I receive this error
message when I click the send button:
