+    \class QAxBindable
+    \brief The QAxBindable class provides an interface between a
+    QWidget and an ActiveX client.
+
+    \inmodule QAxServer
+
+    The functions provided by this class allow an ActiveX control to
+    communicate property changes to a client application. Inherit
+    your control class from both QWidget (directly or indirectly) and
+    this class to get access to this class's functions. The
+    \l{moc}{meta-object compiler} requires you to inherit from
+    QWidget first.
+
+    \snippet doc/src/snippets/code/src_activeqt_control_qaxbindable.cpp 0
+
+    When implementing the property write function, use
+    requestPropertyChange() to get permission from the ActiveX client
+    application to change this property. When the property changes,
+    call propertyChanged() to notify the ActiveX client application
+    about the change. If a fatal error occurs in the control, use the
+    static reportError() function to notify the client.
+
+    Use the interface returned by clientSite() to call the ActiveX
+    client. To implement additional COM interfaces in your ActiveX
+    control, reimplement createAggregate() to return a new object of a
+    QAxAggregated subclass.
+
+    The ActiveQt \l{activeqt/opengl}{OpenGL} example shows how to use
+    QAxBindable to implement additional COM interfaces.
