My program doesn't ask anything when you close it, but it keeps
automatically saving the document in
a temporary file. Thus at every start it loads it up and you're back
where you left.
So I thought I would call the screenshot function at the very end,
while closing down the program.

It didn't work. It didn't save the screenshot of what was there.

So I call it when I receive the expose event (like in the example) and
it does work there.
Why is that?

I still have to investigate it, but I thought the window would be
still available in my Quit function
when called from the destroy event.

Weird.
