How do I know when a QMainWindow is closed?

How can I trigger a function to be called when a QMainWindow is closed? I have a very long loop that I want to abort when the user closes the window. I want that when that happens, a function is called that will set a flag to true, which in turn will tell the loop to finish.

I solved it, after googling for a while I realized that I could do that by overloading the closeEvent function that exists in the class that is derived from QMainWindow by Qt Creator when the project is created.
