Where does InputEvent( ev[i]) get caught?

[ChrisW67]

If you don't want an X11 input event generated from a keyboard like device then you could tell X11 to ignore it from xorg.conf:

Section "InputClass"
    Identifier      "Ignore barcode reader because I am reading it directly through /dev/input/eventx"
    MatchProduct    "Whizzo barcode reader"
    Option          "Ignore" "yes"
EndSection

Section "InputClass"
    Identifier      "Ignore barcode reader because I am reading it directly through /dev/input/eventx"
    MatchProduct    "Whizzo barcode reader"
    Option          "Ignore" "yes"
EndSection

To copy to clipboard, switch view to plain text mode 

Looks like you should be able to intercept raw XEvents by installing a QCoreApplication::setEventFilter() (or QAbstractEventDispatcher::setEventFilter())

Thanks for your response. Was hoping to avoid xorg mod since other targets won't have xorg. Will play with event filter at core application level. Really wanted to get event _after_ translation to Unicode and _before_ it became a keypress event so I wouldn't have to recode the wheel. Will play with this today and see how it turns out.

Thanks again.

You can filter cooked events using qApp->installEventFilter() but by that time you can no longer tell where the key event has come from. QApplication::x11EventFilter() might be easier for raw XEvents. I am not sure you can get the original source device this way either.

I do not think you will find a universal, platform independent manner in which to do this.
