    \class QScreenDriverPlugin

    \ingroup plugins

    \ingroup qws

    \brief The QScreenDriverPlugin class is an abstract base class for

    screen driver plugins in Qt for Embedded Linux.

    Note that this class is only available in \l{Qt for Embedded Linux}.

    \l{Qt for Embedded Linux} provides ready-made drivers for several screen

    protocols, see the \l{Qt for Embedded Linux Display Management}{display

    management} documentation for details. Custom screen drivers can be

    implemented by subclassing the QScreen class and creating a screen

    driver plugin.

    A screen driver plugin can be created by subclassing

    QScreenDriverPlugin and reimplementing the pure virtual keys() and

    create() functions. By exporting the derived class using the

    Q_EXPORT_PLUGIN2() macro, The default implementation of the

    QScreenDriverFactory class will automatically detect the plugin

    and load the driver into the server application at run-time.  See

    \l{How to Create Qt Plugins} for details.

    \sa QScreen, QScreenDriverFactory

*/

/*!

    \fn QStringList QScreenDriverPlugin::keys() const

    Implement this function to return the list of valid keys, i.e. the

    screen drivers supported by this plugin.

    \l{Qt for Embedded Linux} provides ready-made drivers for several screen

    protocols, see the \l{Qt for Embedded Linux Display Management}{display

    management} documentation for details.

    \sa create()

*/

/*!

    Constructs a screen driver plugin with the given \a parent.

    Note that this constructor is invoked automatically by the

    Q_EXPORT_PLUGIN2() macro, so there is no need for calling it

    explicitly.

/*!

    Destroys this screen driver plugin.

    Note that Qt destroys a plugin automatically when it is no longer

    used, so there is no need for calling the destructor explicitly.

/*!

    \fn QScreen* QScreenDriverPlugin::create(const QString &key, int displayId)

    Implement this function to create a driver matching the type

    specified by the given \a key and \a displayId parameters. Note

    that keys are case-insensitive.
