Qt.
<p> It demonstrates how to export existing <a href="qwidget.html">QWidget</a> classes as ActiveX

</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.
<p> <pre> QAXFACTORY_EXPORT( ActiveQtFactory, "{3B756301-0075-4E40-8BE8-5A81DE2426B7}", "{AB068077-4924-406a-BBAF-42D91C8727DD}" )
</pre>The factory is exported using the QAXFACTORY_EXPORT macro.
<p> To build the example you must first build the <a href="qaxserver.html">QAxServer</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.
<p>
<pre> <SCRIPT LANGUAGE=VBScript>
Sub ToolButton_Clicked()
RadioButton.text = InputBox( "Enter something", "Wrapper Demo" )
End Sub
