I'd bet it is...

PasteUpMorph>>windowEvent: anEvent

self windowEventHandler

ifNotNil: [^self windowEventHandler windowEvent: anEvent].

anEvent type == #windowClose

ifTrue: [WorldState quitSession].

and #windowsEvent: is called in a sequence like:

VM event => InputEventFetcher => Morphic event => PasteUpMorph ...

Hello,

I would like to change the behavior of Pharo when the user clicks on the
close button of the host window.

So far it looks like #quitSession is sended from somewhere, but I fail
to see the chain of call between the host window and the #quitSession
message.

Any idea?

Thanks

Hilaire
