\class QWSQnxKeyboardHandler
\preliminary
\ingroup qws
\since 4.6
\internal
\brief The QWSQnxKeyboardHandler class implements a keyboard driver
for the QNX \c{devi-hid} input manager.
To be able to compile this mouse handler, \l{Qt for Embedded Linux}
must be configured with the \c -qt-kbd-qnx option, see the
\l{Qt for Embedded Linux Character Input} documentation for details.
In order to use this keyboard handler, the \c{devi-hid} input manager
must be set up and run with the resource manager interface (option \c{-r}).
Also, Photon must not be running.
Example invocation from command line: \c{/usr/photon/bin/devi-hid -Pr kbd mouse}
Note that after running \c{devi-hid}, you will not be able to use the local
shell anymore. It is suggested to run the command in a shell scrip, that launches
a Qt application after invocation of \c{devi-hid}.
To make \l{Qt for Embedded Linux} explicitly choose the qnx keyboard
handler, set the QWS_KEYBOARD environment variable to \c{qnx}. By default,
the first keyboard device (\c{/dev/devi/keyboard0}) is used. To override, pass a device
name as the first and only parameter, for example
\c{QWS_KEYBOARD=qnx:/dev/devi/keyboard1; export QWS_KEYBOARD}.
\sa {Qt for Embedded Linux Character Input}, {Qt for Embedded Linux}
*/
/*!
Constructs a keyboard handler for the specified \a device, defaulting to
\c{/dev/devi/keyboard0}.
Note that you should never instanciate this class, instead let QKbdDriverFactory
handle the keyboard handlers.
