Ok, then I think you're really outside of the qooxdoo domain. You want the
browser to open up the Save File As dialog to allow the user to save the
file. I think you should be able to do that with an Iframe most easily
without doing anything with qooxdoo. I've never actually tried to do what
you're attempting, though, so I don't have explicit instructions for you.
I believe you'll have to arrange for the server to provide a MIME type that
the browser doesn't know what to do with, in order for the browser to open
that Save As dialog. If you send the CSV file back as text/plain, the
browser will likely just render it in the Iframe. Sending it as
application/something may be appropriate, but I'm not sure of the best way
to handle this.
