    72     \brief The QMouseDriverFactory class creates mouse drivers in
       
    73     Qt for Embedded Linux.
       
    74 
       
    75     Note that this class is only available in \l{Qt for Embedded Linux}.
       
    76 
       
    77     QMouseDriverFactory is used to detect and instantiate the
       
    78     available mouse drivers, allowing \l{Qt for Embedded Linux} to load the
       
    79     preferred driver into the server application at runtime. The
       
    80     create() function returns a QWSMouseHandler object representing
       
    81     the mouse driver identified by a given key. The valid keys
       
    82     (i.e. the supported drivers) can be retrieved using the keys()
       
    83     function.
       
    84 
       
    85     \l{Qt for Embedded Linux} provides several built-in mouse drivers. In
       
    86     addition, custom mouse drivers can be added using Qt's plugin
       
    87     mechanism, i.e. by subclassing the QWSMouseHandler class and
       
    88     creating a mouse driver plugin (QMouseDriverPlugin). See the
       
    89     \l{Qt for Embedded Linux Pointer Handling}{pointer handling}
       
    90     documentation for details.
