\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.
*/
QScreenDriverPlugin::QScreenDriverPlugin(QObject *parent)
: QObject(parent)
{
}
/*!
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.
*/
QScreenDriverPlugin::~QScreenDriverPlugin()

}
/*!
\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.
