Because of the problem I am experiencing described here Cannot use keyboard within Qt app without sudo and here Qt embedded linux event watcher I was wondering either there is in Qt, an event watcher? I Have found library named QFileSystemWatcher but it doesnt work with devices, only with regular files. Also I have found a 3rd party library for this QDeviceWatcher but it only consists signals for when a new device is inserted or removed, not when it changes (for example I press a key). I need to watch a keyboard device /dev/input/event1 for key strokes. I would apreciate all help!

I think you're looking for the wrong fix to your problem. You should debug why Qt can't reliably open `/dev/input/event1`. – peppe Jul 03 '15 at 09:02

@peppe I am trying to do that for over a week now and I cannot figure it out. This only occurs when i run the app remotelly through ssh or via rc.local script. I am not proud of this solution but its what i got left I believe. – Łukasz Przeniosło Jul 03 '15 at 09:03

You *can* attach to a running process using remote gdb, so you should be able to debug it. If you somehow can't debug it, you should post a question describing exactly what you're doing, and where does the debugging fail. You'll of course need a self-built debug Qt. – Kuba hasn't forgotten Monica Jul 06 '15 at 13:10
