    \title Qt WebChannel Standalone Example
    \ingroup qtwebchannel-examples
    \image standalone-screenshot.png
    \brief Shows how to use the QWebChannel C++ API to communicate with an external client.

    The standalone example is a simple chat between a C++ application and a remote HTML
    client running in your default browser.

    \include examples-run.qdocinc

    \section1 Overview

    The C++ application sets up a QWebChannel instance and publishes a Dialog object over it.
    For the remote client side, \l {standalone/index.html}{index.html} is opened. Both show a
    dialog with the list of received messages and an input box to send messages to the other end.

    The Dialog emits the Dialog::sendText() signal when the user sends a message. The signal
    automatically gets propagated to the HTML client. When the user enters a message on the HTML
    side, Dialog::receiveText() is called.

    All communication between the HTML client and the C++ server is done over a WebSocket.
    The C++ side instantiates a QWebSocketServer and wraps incoming QWebSocket connections
    in WebSocketTransport objects, which implement QWebChannelAbstractTransport. These objects are
    then connected to the QWebChannel instance.
