    \class QAxWidget
    \brief The QAxWidget class is a QWidget that wraps an ActiveX control.

    \inmodule QAxContainer

    A QAxWidget can be instantiated as an empty object, with the name
    of the ActiveX control it should wrap, or with an existing
    interface pointer to the ActiveX control. The ActiveX control's
    properties, methods and events which only use QAxBase
    supported data types, become available as Qt properties,
    slots and signals. The base class QAxBase provides an API to
    access the ActiveX directly through the \c IUnknown pointer.

    QAxWidget is a QWidget and can mostly be used as such, e.g. it can be
    organized in a widget hierarchy and layouts or act as an event filter.
    Standard widget properties, e.g. \link QWidget::enabled
    enabled \endlink are supported, but it depends on the ActiveX
    control to implement support for ambient properties like e.g.
    palette or font. QAxWidget tries to provide the necessary hints.

    However, you cannot reimplement Qt-specific event handlers like
    mousePressEvent or keyPressEvent and expect them to be called reliably.
    The embedded control covers the QAxWidget completely, and usually
    handles the user interface itself. Use control-specific APIs (i.e. listen
    to the signals of the control), or use standard COM techniques like
    window procedure subclassing.

    QAxWidget also inherits most of its ActiveX-related functionality
    from QAxBase, notably dynamicCall() and querySubObject().

    \warning
    You can subclass QAxWidget, but you cannot use the \c Q_OBJECT macro
    in the subclass (the generated moc-file will not compile), so you
    cannot add further signals, slots or properties. This limitation
    is due to the metaobject information generated in runtime. To work
    around this problem, aggregate the QAxWidget as a member of the
    QObject subclass.
