I do not see any API to set the priority of a QProcess in Qt Documentation. I assume the process is started with normal priority.
Is there a way to start the process with lower priority on Linux?
I dont think there exists an API to set the priority of the process using a Qt call. I used direct Linux calls and was successfully able to change the process priority.
