is it possible to notice if a second window (made with screen class) is manually closed by the user?

is it possible to notice if a second window (made with screen class, https://wiki.gideros.rocks/index.php/Screen) is manually closed by the user? is there an event to listen or some value to check?
i have a vague memory that i've asked this and the answer was no but let me ask it again, hopefully i'm wrong.
thanks

I think there is no way to attach an event to Screen object, but you can check its state every frame?

if ((window:getState() & Screen.STATE_CLOSED) > 0) then 
end
-- or maybe this
if (window:getState()  == Screen.STATE_CLOSED | Screen.STATE_HIDDEN) then 
end

thanks, the first seems to work fine. the second solution too but i did test it less.
