<div class="descr"> <a name="details"></a>
<p>WebSocket is a web-based protocol designed to enable two-way communication between a client application and a remote host. It enables the two entities to send data back and forth if the initial handshake succeeds. WebSocket is the solution for applications that struggle to get real-time data feeds with less network latency and minimum data exchange.</p>
<p>The Qt WebSockets module provides C++ and QML interfaces that enable Qt applications to act as a server that can process WebSocket requests, or a client that can consume data received from the server, or both.</p>

<p>To include the definitions of the module's classes, use the following directive:</p>
<pre class="cpp">
<span class="preprocessor">#include <QtWebSockets/QtWebSockets></span>
</pre>
<p>To import the QML types into your application, use the following import statement in your .qml file:</p>
<pre class="cpp">
import <span class="type"><a href="qtwebsockets-module.html">QtWebSockets</a></span> <span class="number">1.0</span>
</pre>
<p>To link against the module, add this line to your qmake .pro file:</p>
<pre class="cpp">
QT <span class="operator">+</span><span class="operator">=</span> websockets
</pre>
