</pre>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.

</pre>The factory is exported using the TQAXFACTORY_EXPORT macro.
<p> To build the example you must first build the <a href="qaxserver.html">TQAxServer</a> library. Then run qmake and your make tool in
<tt>examples/wrapper</tt>.
<p> <hr>
<p> The <a href="qaxserver-demo-wrapper.html">demonstration</a> requires your
WebBrowser to support ActiveX controls, and scripting to be enabled.
