+ \class QScreenDriverFactory
+ \ingroup qws
+
+ \brief The QScreenDriverFactory class creates screen drivers in
+ Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ QScreenDriverFactory is used to detect and instantiate the
+ available screen drivers, allowing \l{Qt for Embedded Linux} to load the
+ preferred driver into the server application at runtime. The
+ create() function returns a QScreen object representing the screen
+ driver identified by a given key. The valid keys (i.e. the
+ supported drivers) can be retrieved using the keys() function.
+
+
+ \l{Qt for Embedded Linux} provides several built-in screen drivers. In
+ addition, custom screen drivers can be added using Qt's plugin
+ mechanism, i.e. by subclassing the QScreen class and creating a
+ screen driver plugin (QScreenDriverPlugin). See the
+ \l{Qt for Embedded Linux Display Management}{display management}
+ documentation for details.
