Windows and Linux... I don't know if it detatches on linux.. I just know that if I manually kill the UI while the CLI version is running, Ill have to track it down in the task manager later..

Can you confirm the following is how you made it? In my experiment, the following way makes the newly created process terminate when the GUI crashes. QProcess *proc = new QProcess; connect(proc, SIGNAL(readyReadStandardError()), this SLOT(readStderr())); proc->start(); Thanks, Yifei On Mon, Jul 1, 2013 at 6:28 PM, Scott Aron Bloom <scott.bl...@onshorecs.com<mailto:scott.bl...@onshorecs.com>> wrote: Im completely confused on what you are trying to do.. I can tell you that, I have a QProcess variable, and I have attached to the "stdout/stderr available signals".. When they trigger, I get the stdout and stderr And if the GUI crtashes while the CLI call is running, the CLI keeps running.
