<p>The Multiple example demonstrates the implementation of a <a href="qaxfactory.html">QAxFactory</a> to provide multiple ActiveX controls in a single in process ActiveX server using the <tt>QAXFACTORY_EXPORT()</tt> macro. The ActiveX controls in this example are simple <a href="qwidget.html">QWidget</a> subclasses that reimplement <a href="qwidget.html#paintEvent">QWidget::paintEvent</a>().</p>
