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}.
