<p>The factory implementation returns the list of supported controls, creates controls on request and provides information about the unique IDs of the COM classes and interfaces for each control.</p>

<p>The factory is exported using the QAXFACTORY_EXPORT macro.</p>
<p>To build the example you must first build the <a href="qaxserver.html">QAxServer</a> library. Then run <tt>qmake</tt> and your make tool in <tt>examples/activeqt/wrapper</tt>.</p>
<p>The <a href="qaxserver-demo-wrapper.html">demonstration</a> requires a web browser that supports ActiveX controls, and scripting to be enabled.</p>
