How do I prevent closing NWJS window with ALT-F4?

I need to prevent closing my game when users press Alt-F4. Instead, I want to and exit the game gracefully by showing a dialog like "Do you want to quit the game? Any unsaved progress will be lost. Yes/No"

Is there any way to do this with NWJS export?

Hello my freinds...

I need to know if you are in Windows or Linux ?!

I will need it to work on Windows and possibly MacOS.

Someone just answered me in this old post, but I wonder if there is an easier and less hacky solution.

Have you tried using the keyboard object and "intercepting" the keyboard combination ALT+F4 ? (On Alt is down And F4 is down; trigger once while true)

I saw window.onbeforeunload referenced in a few places when searching for close confirmation in JavaScript. Don't know if it will work with nwjs or not.

I can try this, but what's next? I will not be able to prevent the window from closing.

oosyrag I'll try it, thanks!

I was hoping that the keyboard input would be caught (like Space bar in browsers).

Unfortunately it does not seem to be the case from my test.

Perhaps Ashley will have an alternative solution.

Can't you just put the JS code from the other thread in a script in Construct? That post is from the old C2 forum, but C3's JavaScript coding feature is ideal for snippets like that.
