But when I run the app on the remote host through QtCreator, it fails to connect to a display, because it does not exist. The solution is to access to remote host with `-X` option. Definitely. This way it opens window(s) on a local (development) machine.

Have you set the environment variable DISPLAY to ":0" (or whatever is
correct) on your run environment?
