<P>
<p>The <a href="QTcpServer.html#QTcpServer(com.trolltech.qt.core.QObject)"><tt>QTcpServer</tt></a> class provides a TCP-based server.</p>
<p>This class makes it possible to accept incoming TCP connections. You can specify the port or have <a href="QTcpServer.html#QTcpServer(com.trolltech.qt.core.QObject)"><tt>QTcpServer</tt></a> pick one automatically. You can listen on a specific address or on all the machine's addresses.</p>
<p>Call listen() to have the server listen for incoming connections. The <a href="QTcpServer.html#newConnection()"><tt>newConnection</tt></a> signal is then emitted each time a client connects to the server.</p>
<p>Call <a href="QTcpServer.html#nextPendingConnection()"><tt>nextPendingConnection</tt></a> to accept the pending connection as a connected <a href="QTcpSocket.html"><tt>QTcpSocket</tt></a>. The function returns a pointer to a <a href="QTcpSocket.html"><tt>QTcpSocket</tt></a> in QAbstractSocket::ConnectedState that you can use for communicating with the client.</p>
<p>If an error occurs, <a href="QTcpServer.html#serverError()"><tt>serverError</tt></a> returns the type of error, and <a href="QTcpServer.html#errorString()"><tt>errorString</tt></a> can be called to get a human readable description of what happened.</p>
<p>When listening for connections, the address and port on which the server is listening are available as <a href="QTcpServer.html#serverAddress()"><tt>serverAddress</tt></a> and serverPort().</p>
<p>Calling <a href="QTcpServer.html#close()"><tt>close</tt></a> makes <a href="QTcpServer.html#QTcpServer(com.trolltech.qt.core.QObject)"><tt>QTcpServer</tt></a> stop listening for incoming connections.</p>
<p>Although <a href="QTcpServer.html#QTcpServer(com.trolltech.qt.core.QObject)"><tt>QTcpServer</tt></a> is mostly designed for use with an event loop, it's possible to use it without one. In that case, you must use waitForNewConnection(), which blocks until either a connection is available or a timeout expires.</p>
