+ \title Qt WebChannel Chatserver Example
+ \ingroup qtwebchannel-examples
+ \brief Shows how to use the QWebChannel C++ API to implement a simple chat server
+
+ The chatserver examples provides a chat service that client examples can connect to.
+
+ \section1 Overview
+
+ The C++ application implements a QObject which provides all mechanisms required for
+ a chat service.
+ This object is published through a QWebChannel which uses a WebSocket as transport.
+
+ The server provides a basic \c login method (username only, no passwords), which must be
+ successfully invoked before a client is able to chat.
+ After login a client can invoke the method \c sendMessage and receive the signal \c newMessage
+ to write and receive messages. Furthermore there is a \c userList property which provides
+ the names of all other connected clients.
+ Additionally the server sends a keepAlive signal periodically to all clients. The clients
+ have to respond to this signal, otherwise the client will be removed from the \c userList property.
+
+ The example shows how basic QObject elements can be used with QWebChannel, i.e. signals
+ (\c newMessage), slots (\c sendMessage) and properties (\c userList).
+
+ Because this is a plain server application, there are separated clients needed to interact
+ with the server. Both examples chatclient-qml and chatclient-html show a client implementation
+ compatible with this server.
