QProcess exits the application after calling QProcess.start()

I am using QProcess to run other programs. But when I exit my app after calling QProcess.start() it says in debug console:

QProcess: Destroyed while process is still running.

and the process closes.

But I want to keep this process running after closing my app. How I start new process:

QProcess p;
p.start("ssu.exe", QStringList() << "-instantinstall");

How do I do that?

Solution

  • You need to use QProcess::startDetached. See the docs:

    If the calling process exits, the detached process will continue to live.
