37-
38 \brief The QTcpServer class provides a TCP-based server.-
39-
40 \reentrant-
41 \ingroup network-
42 \inmodule QtNetwork-
43-
44 This class makes it possible to accept incoming TCP connections.-
45 You can specify the port or have QTcpServer pick one-
46 automatically. You can listen on a specific address or on all the-
47 machine's addresses.-
48-
49 Call listen() to have the server listen for incoming connections.-
50 The newConnection() signal is then emitted each time a client-
51 connects to the server.-
52-
53 Call nextPendingConnection() to accept the pending connection as-
54 a connected QTcpSocket. The function returns a pointer to a-
55 QTcpSocket in QAbstractSocket::ConnectedState that you can use for-
56 communicating with the client.-
57-
58 If an error occurs, serverError() returns the type of error, and-
59 errorString() can be called to get a human readable description of-
60 what happened.-
61-
62 When listening for connections, the address and port on which the-
63 server is listening are available as serverAddress() and-
64 serverPort().-
65-
66 Calling close() makes QTcpServer stop listening for incoming-
67 connections.-
68-
69 Although QTcpServer is mostly designed for use with an event-
70 loop, it's possible to use it without one. In that case, you must-
71 use waitForNewConnection(), which blocks until either a-
72 connection is available or a timeout expires.-
