    <p>Trying to convert a server written in C++ into Python. The server was written to be Asynchronous/Non Blocking. What works in C++ doesn't seem to want to work for me in Python</p> <p>I am using PyQT4. I read Python you have to create the event loop or something along those lines any ideas are greatly appreciated</p> <p>I should mention what seems to not work is that the <strong>incomingConnection</strong> function in Class Server is never called. </p> <p>*cheers</p> <pre><code>import sys from PyQt4.QtCore import * from PyQt4.QtNetwork import * class Client(QObject): def __init__(self, parent=None): QObject.__init__(self) QThreadPool.globalInstance().setMaxThreadCount(15) def SetSocket(self, Descriptor): self.socket = QTcpSocket(self) self.connect(self.socket, SIGNAL("connected()"), SLOT(self.connected())) self.connect(self.socket, SIGNAL("disconnected()"), SLOT(self.disconnected())) self.connect(self.socket, SIGNAL("readyRead()"), SLOT(self.readyRead())) self.socket.setSocketDescriptor(Descriptor) print "Client Connected from IP %s" % self.socket.peerAddress().toString() def connected(self): print "Client Connected Event" def disconnected(self): print "Client Disconnected" def readyRead(self): msg = self.socket.readAll() print msg class Server(QObject): def __init__(self, parent=None): QObject.__init__(self) def incomingConnection(self, handle): print "incoming" self.client = Client(self) self.client.SetSocket(handle) def StartServer(self): self.server = QTcpServer() if self.server.listen(QHostAddress("0.0.0.0"), 8888): print "Server is awake" else: print "Server couldn't wake up" def main(): app = QCoreApplication(sys.argv) Server().StartServer() sys.exit(app.exec_()) if __name__ == '__main__': main() </code></pre>

    1. COThis really doesn't seem to be a situation for this library; probably you would be better off using basic sockets and threads.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
