Qt handling of SIGKILL etc..

[Perdrix]

Do I need to add a signal handler in my main() and do something there to tell Qt App.exec() to close or is that already handled by QCoreApplication?

Thanks

Well if you are talking about Linux SIGKILL, kill -9, programs cannot catch/handle it anyway, it's a nuke signal. Can't say for sure what it does under Windows.

For other signals you might like to read through https://doc.qt.io/qt-6/unix-signals.html, and perhaps the further detail in https://codereview.stackexchange.com/questions/175131/safely-and-elegantly-handling-unix-signals-in-qt-applications. All looks like a lot of work! :)

You're right, I was thinking more of SIGTERM and SIGINT etc. not sure why I put SIGKILL in the title of the thread (mental hiccup).
