LinuxQuestions.org - Qt asynchronous sockets problem

Hey everybody,
I'm trying to write a simple, four-player card game to play over the network using the QT4 toolkit. I've set up a protocol (client/server) such that I always know when I must do sending and when I must do recieving. Unfortunatly using the sockets system is causing me epic headaches!
The problem is, I don't want to block the GUI by using QTcpSocket::waitForReadyRead(). What I had in mind was using blocking I/O in a thread whenever it was necessary and catching the thread's terminate signal in my main loop...but then I have no way of knowing which socket (player) I just finished sending data to!
Idealy, i'd like to do something like this...

(in the server)

Code:

class MyIOThread : public QThread

{

public:

QTcpSocket* socket;

....other game data....

int result;

void run(); };



void MyIOThread::run(){ some code using data and socket->read(); set this.result; return;}



...ive decided some recieving needs to be done from the client...

MyIOThread* thethread = new MyIOThread;

thethread->socket = some_socket_somewhere;

connect(thethread, SIGNAL(terminate()), this, SLOT(aslot()));



void aslot()

{

do soemthing with MyIOThread_instance_that_I_declared_before.result

}

So is there a way i can find out exactly what instance of a class fired the signal i'm now handling in that slot?
Thanks
