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.
