<p>The Wrapper example demonstrates how to export existing <a href="qwidget.html">QWidget</a> classes as ActiveX controls, and the use of <a href="qaxfactory.html">QAxFactory</a> together with the <tt>QAXFACTORY_EXPORT()</tt> macro. ActiveX controls in this example are the standard button classes <a href="qpushbutton.html">QPushButton</a>, <a href="qcheckbox.html">QCheckBox</a> and <a href="qradiobutton.html">QRadioButton</a> as provided by Qt.</p>

<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>

111

<pre>  QAXFACTORY_EXPORT( ActiveQtFactory, "{3B756301-0075-4E40-8BE8-5A81DE2426B7}", "{AB068077-4924-406a-BBAF-42D91C8727DD}" )</pre>

112

<p>The factory is exported using the QAXFACTORY_EXPORT macro.</p>

113

<p>To build the example you must first build the <a href="qaxserver.html#qaxserver">QAxServer</a> library. Then run <tt>qmake</tt> and your make tool in <tt>examples/activeqt/wrapper</tt>.</p>

114

<p>The <a href="qaxserver-demo-wrapper.html">demonstration</a> requires your WebBrowser to support ActiveX controls, and scripting to be enabled.</p>
