I can use intialization/finalization do run some cleanup code and this works fine so far.

But would it be possible to have the onbeforeunload event in order to do some checks (e.g. for
unsaved data) and let the user confirm, that he wants to close the window?

I could probably look into adding something that allows for this, but displaying a modal dialog, etc. at that point would not be wise.  Your application should simply assume that it can go away at any time, and should work accordingly by doing auto-saving, etc. using a timer or some other method.

I think there will be only non visual code to check if the app can be closed and then the event
returns a message, that will be shown in a confirmation dialog of the browser. So no UI stuff there
anymore.

I have seen that in different applications, e.g. Outlook Web mail.

What exactly is the confirmation dialog, if not UI ?

But yes, I know what you're referring to (OnBeforeUnload event).  I'll have to check into this to see how consistent the behavior is across the various browsers.  I think there are some issues with Mobile Safari firing this event.

You can try creating the event as described here:
