+ \class QMouseDriverFactory
+ \ingroup qws
+
+ \brief The QMouseDriverFactory class creates mouse drivers in
+ Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ QMouseDriverFactory is used to detect and instantiate the
+ available mouse drivers, allowing \l{Qt for Embedded Linux} to load the
+ preferred driver into the server application at runtime. The
+ create() function returns a QWSMouseHandler object representing
+ the mouse 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 mouse drivers. In
+ addition, custom mouse drivers can be added using Qt's plugin
+ mechanism, i.e. by subclassing the QWSMouseHandler class and
+ creating a mouse driver plugin (QMouseDriverPlugin). See the
+ \l{Qt for Embedded Linux Pointer Handling}{pointer handling}
+ documentation for details.
