\class QKbdDriverFactory
\ingroup qws
\brief The QKbdDriverFactory class creates keyboard drivers in
Qt for Embedded Linux.
Note that this class is only available in \l{Qt for Embedded Linux}.
QKbdDriverFactory is used to detect and instantiate the available
keyboard drivers, allowing \l{Qt for Embedded Linux} to load the preferred
driver into the server application at runtime. The create()
function returns a QWSKeyboardHandler object representing the
keyboard 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 keyboard drivers. In
addition, custom keyboard drivers can be added using Qt's plugin
mechanism, i.e. by subclassing the QWSKeyboardHandler class and
creating a keyboard driver plugin (QKbdDriverPlugin). See the
\l{Qt for Embedded Linux Character Input}{character input} documentation
for details.
