Keyboard doesn't attach after application start - Raspberry Pi

creasser

Hi,
keyboard in app works fine until I unplug and plug in my keyboard again. Then it stops working in QT application and output goes directly to console (but of course app still covers console) - I found it out when I logged in via ssh and kill the app.

QT version 4.7.

Is there anybody who faced a similar problem?

Thanks a lot for ur replies.

Hi,

AFAIK, when starting the application, Qt detects (or you tell it) what device to use. When unplugging and replugging, your kernel is probably creating a new device which is not the same as the one used by your application.

I'd say it too.
And is there any fix?

Don't play with the keyboard or use your OS to detect that and restart your application.

@SGaist: Yeah, of course, I thought of that. But isn't there any procedure to re-attach keyboard during app run in QT?

Not that I know of, but you can try asking on the interest mailing list. You'll find Qt's developers/maintainers there (this forum is more user oriented)
