[next] Prevent app close

Hello. Target: cpp, next;

I can’t find the main close event to replace/prevent it.
This topic did not help.
Using Lib.current.stage.application.onExit.add, I can only add an additional function

Thank you


did not work :frowning:

Have you tried adding a listener to window.onClose, and canceling from there?

Note that this will only work on native targets, if it works at all. (“Try to allow exit to be canceled” isn’t very reassuring.)

I can not make what I want, neither solution does not work, I need a working example code. It’s trivial task, why is it so difficult. :persevere:
