+
+    \section1 Build Instructions
+
+    Qt for QNX needs to be built either on a QNX system, or \l{Cross-Compiling Qt
+    for Embedded Linux Applications}{cross-compiled} on a Linux host. In either
+    case, The QNX Software Development Platform must be installed.
+
+    Example configure line for cross-compiling Qt for QNX on a Linux host for an
+    i386 QNX target:
+
+    \code
+    configure -xplatform unsupported/qws/qnx-i386-g++ -embedded i386 -no-gfx-linuxfb -no-mouse-linuxtp -no-kbd-tty -no-qt3support -qt-gfx-qnx -qt-mouse-qnx -qt-kbd-qnx -no-exceptions
+    \endcode
+
+    \list
+    \o \c{-xplatform unsupported/qws/qnx-i386-g++} - selects the i386-g++ mkspec for QNX
+    \o \c{-embedded i386} - builds the embedded version of Qt and sets the architecture to i386
+    \o \c{-no-gfx-linuxfb},  \c{-no-mouse-linuxtp} and \c{-no-kbd-tty} are Linux specific and won't work on QNX
+    \o \c{-no-qt3support} - required since the Qt3 support classes are not supported on QNX
+    \o \c{-no-exceptions} - reduces the size of the library by disabling exception support
+    \o \c{-qt-gfx-qnx} - enables the experimental \c{io-graphics} based display driver
+    \o \c{-qt-mouse-qnx} - enables the experimental \c{devi-hig} based mouse driver
+    \o \c{-qt-kbd-qnx} - enables the experimental \c{devi-hig} based keyboard driver
+    \endlist
+
+    \section1 General Notes
+
+    \list
+    \o To enable the experimental QNX display and input drivers, \c{io-display} needs to be
+       up and running. The \c devi-hid based Qt input drivers require \c devi-hid to run
+       in resource mode without Photon support. To enable a standard mouse and keyboard
+       combination, run \c devi-hid as follows: \c{/usr/photon/bin/devi-hid -Pr kbd mouse}.
+       Note that your current shell will not accept keyboard and mouse input anymore after
+       running that command, so run it either from a script that launches a Qt application
+       afterwards, or make sure to have remote login available to launch a Qt application.
+       In addition, the \c QWS_DISPLAY, \c QWS_MOUSE_PROTO and \c QWS_KEYBOARD environment
+       variables should all be set to \c{qnx} before running a Qt application.
+
+    \o The 3rd party TIFF library currently doesn't build due to the missing \c inflateSync
+       symbol from QNX's \c{libz.so.2}. Workarounds would be to manually replace QNX's libz
+       with a newer version, or disable the TIFF plugin entierly by appending
+       \c{QT_CONFIG += no-tiff} to \c{.qmake.cache} after configuring Qt.
+
+    \o Some of the tools, examples and demos do not compile due to dependencies on QProcess
+       or other classes that are not available on QNX.
+    \endlist
+
+    \section1 Platform Regressions
+
+    Qt for QNX's behavior is mostly identical with \l{Qt for Embedded Linux}. However,
+    some regressions were spotted in QDateTime computation around year 0 and year 1970,
+    which have been tracked back to faulty time zone data on some QNX versions.

+    \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}.

+
+    \brief The QQnxMouseHandler class implements a mouse 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-mouse-qnx option, see the
+    \l{Qt for Embedded Linux Pointer Handling}{Pointer Handling} documentation for details.
+
+    In order to use this mouse 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 mouse
+    handler, set the QWS_MOUSE_PROTO environment variable to \c{qnx}. By default,
+    the first mouse device (\c{/dev/devi/mouse0}) is used. To override, pass a device
+    name as the first and only parameter, for example
+    \c{QWS_MOUSE_PROTO=qnx:/dev/devi/mouse1; export QWS_MOUSE_PROTO}.

+    \class QQnxScreen
+    \preliminary
+    \ingroup qws
+    \since 4.6
+    \internal
+
+    \brief The QQnxScreen class implements a screen driver
+    for QNX io-display based devices.
+
+    Note - you never have to instanciate this class, the QScreenDriverFactory
+    does that for us based on the \c{QWS_DISPLAY} environment variable.
+
+    To activate this driver, set \c{QWS_DISPLAY} to \c{qnx}.
+
+    Example:
+    \c{QWS_DISPLAY=qnx; export QWS_DISPLAY}
+
+    By default, the main layer of the first display of the first device is used.
+    If you have multiple graphic cards, multiple displays or multiple layers and
+    don't want to connect to the default, you can override that with setting
+    the corresponding options \c{device}, \c{display} or \c{layer} in the \c{QWS_DISPLAY} variable:
+
+    \c{QWS_DISPLAY=qnx:device=3:display=4:layer=5}
+
+    In addition, it is suggested to set the physical width and height of the display.
+    QQnxScreen will use that information to compute the dots per inch (DPI) in order to render
+    fonts correctly. If this informaiton is omitted, QQnxScreen defaults to 72 dpi.
+
+    \c{QWS_DISPLAY=qnx:mmWidth=120:mmHeight=80}
+
+    \c{mmWidth} and \c{mmHeight} are the physical width/height of the screen in millimeters.
