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() */ /*!
