+ \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.

+ \sa QKbdDriverFactory
