Using psychopy from a gui ... how to stop psychopy

[Jason Steffener]

Hello.

I wrote a GUI to launch all of my psychopy experiments.

The gui uses Tkinter and is simply a bunch of buttons which each launch my psychopy experiment.

If my experiment is running and I press "escape" my experiment window closes as well as my GUI window.

I would like to keep my GUI window open, I therefore removed the core.quit() function from the code piece:

# check for quit (the Esc key)

            if endExpNow or event.getKeys(keyList=["escape"]):

                win.close()

                # core.quit()

But with this the experiment keeps running but with no window!

Can I press escape and have my experiment stop and its window close but NOT my GUI?

Thank you for feedback.

Check out how coder.py and builder.py launch experiment scripts. That will probably work for you too.

I figured it out using sys.exit()

# check for quit (the Esc key)

            if endExpNow or event.getKeys(keyList=["escape"]):

                win.close()

                sys.exit()

Thanks for the clues Jeremy.

Hi Jason,

I think core.quit() does some PsychoPy housework before exiting (e.g. ensuring all data saving is completed, files closed etc). You might want to check that you aren't missing out on any of that (probably less of an issue if you are writing your own experiments rather than using Builder, but still…)

Regards,

Michael
