    \class QAccessibleWidget
    \brief The QAccessibleWidget class implements the QAccessibleInterface for QWidgets.

    \ingroup accessibility

    This class is convenient to use as a base class for custom
    implementations of QAccessibleInterfaces that provide information
    about widget objects.

    The class provides functions to retrieve the parentObject() (the
    widget's parent widget), and the associated widget(). Controlling
    signals can be added with addControllingSignal(), and setters are
    provided for various aspects of the interface implementation, for
    example setValue(), setDescription(), setAccelerator(), and
    setHelp().
