Yes that is exactly what I do.. From: Yifei Li [mailto:yifl...@gmail.com] Sent: Monday, July 1, 2013 7:29 PM To: Scott Aron Bloom Cc: interest@qt-project.org Subject: Re: [Interest] Redirect stdout to a file
Hi Scott, What I'm trying to do is exactly the same as what you did. 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.
