\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.
