    \class QGfxDriverFactory qgfxdriverfactory.h
    \brief The QGfxDriverFactory class creates QScreen objects for Qt/Embedded.

    The graphics driver factory creates a QScreen object for a given
    key with QGfxDriverFactory::create(key).

    The drivers are either built-in or dynamically loaded from a
    driver plugin (see \l QGfxDriverPlugin).

    QGfxDriverFactory::keys() returns a list of valid keys. Qt
    currently ships with "LinuxFb".

    This class is only available in Qt/Embedded.
*/

/*!
    Creates a QScreen object of a type that matches \a key, and with
    the ID, \a displayId. The QScreen object returned may be from a
    built-in driver, or from a driver plugin.
