Hi,
I have two clients which are connected to a listener. My clients are QTCPSockets and my listener is QTCPServer.
When new connection arrived, I send a message to clients just for test purpose and it's working.
What I want to do is a simple client messaging. i.e. one client send message to another and vice versa. But whenever I write a block from client to another, the problem occurs - that no message is sent to receiver client. My writing policy does not involve Listener. I simply
class Client // assume it's sender client object
{
...
QByteArray data;
data.append("Hello");
int n = clientReceiver->write(data);
emit clientReceiver->readyRead();
...
}
By the way I checked the documentation and I encountered the following sentence "Note for developers implementing classes derived from QIODevice: you should always emit readyRead() when new data has arrived...". I also emitted readyRead as you see above.
What is the deal here?
