    \class QtUiTest::WidgetFactory
    \inpublicgroup QtUiTestModule
    \brief The WidgetFactory class provides a factory interface
    for QtUiTest widget wrapper classes.

    QtUiTest::WidgetFactory is an abstract base class which enables the
    creation of QtUiTest wrapper objects around Qt widgets.

    Customizing QtUiTest behaviour for particular widgets is achieved by
    implementing one or more test widget classes which inherit from
    one or more QtUiTest widget interfaces,
    subclassing QtUiTest::WidgetFactory, reimplementing the pure virtual
    keys() and create() functions to create instances of the custom test
    widget classes, and exporting the factory class using the
    Q_EXPORT_PLUGIN2() macro.
*/

/*!
    \fn QtUiTest::WidgetFactory::create(QObject* object)

    Attempts to create a test widget to wrap \a object.  Returns the created
    test widget.  Returns 0 if this factory does not support wrapping
    \a object.

    The returned object is suitable for use with
    \l{QtUiTest}{qtuitest_cast}.

    This function will only be called for objects which inherit one of the
    classes returned by keys().
*/

    Returns the list of C++ class names this factory can generate test widgets

    Note that returning a class from this function does not guarantee that the
    factory will always be able to generate a test widget for that class.

    \brief The Widget class provides an abstract base class

    QtUiTest::Widget encapsulates important information
    and functionality related to two-dimensional GUI elements.

    All test widgets should implement the QtUiTest::Widget interface,
    using multiple inheritance to implement other QtUiTest interfaces
    where suitable.
