+    \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.
