First of all, the example seems to be incomplete, there's no app.exec_() and nothing creates a Server object. However your problem lies in the init function of the Server. It waits for the worker-thread to finish. Since you create the server from the main thread as it seems you block the event processing and hence no gui-updates and no cross-thread signals work. This does not make any sense, since the point of a thread is to do work in parallel and in your case your serializing everything again.
