    \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.
