Ура! Thank you, guys for support and ideas.
Now I can make the app running on a remote machine open its graphics on a local
development machine.
Steps:
1. Open ssh session with X forwarding enabled
ssh -X user@host
2. Get know forwarded display identity:
echo $DISPLAY
Will return something like `localhost:11.0`
3.Set environment variable DISPLAY for your run configuration in QtCreator to
that value like `localhost:11.0`
4. Enjoy.
