Hello, i got stuck while trying writing to a threaded server. Receiving works fine but the other way around...
Method readData() at tcpsocket.cpp is never called. What am I doing wrong?

Server:

Qt Code: 
  1. MultiServer server;
  2.      if (!server.listen(QHostAddress::Any, 15000)) {
  3.          close();
  4.          return;
  5.      }

  8. {
  9.     QString msg = "Message from server";
  10.     ConnectionThread *thread = new ConnectionThread(socketDescriptor, msg, this);
  11.     connect(thread, SIGNAL(finished()), thread, SLOT(deleteLater()));
  12.     thread->start();
