Can you configure Qt Creator to kill the running application before building or running?

Question

I'm developing a QApplication and I find that I often forget to close my application before rebuilding and re-running it. This becomes a problem when I accidentally look at an instance of my application built 10 minutes ago and expect to see code changes from 30 seconds ago.

It is also annoying because I have to move my hand all the way over to the mouse, move the mouse all the way over to the running application, and close it every time I want to rebuild and I am lazy and I don't want to do that.

Is it possible to configure Qt Creator to close my QApplication when I start building or running it again?

Answer 1

There is an option to do that in Qt Creator:

1. Open the Preferences => Build & Run => General
2. Change “Stop application before building” from “None” to “Same Project”

Answer 2

To whomever might stumble here later, an easier way to o this is to put a "killall" command (as suggested by tangbongbong) is the first build step under Projects(ctrl+5) -> Build and Run

In the screenshot below my executable name was "Tutano" and I added the -9 option to ensure it would be killed.
