Check file if the file is writable or used by another process

Unfortunately there is no file locking in Unix.
What you can do is call a system command and use a combination of fuser and grep to find if some other process is using the file.

unix create a ".~lock.filename#" logfile. but i have hope there is a better way to handle this. We are open the file with QDesktopService:penUrl(...);

Unix doesn't create any lock files. If an application doesn't lock the file for exclusive access (and on Unix applications rarely do that), there is no way of knowing if a file is open other than processing the /proc tree (if it exists and you have access to it).
