This won't make $window and $text additional arguments for the callback,
but they will become a key and value pair in a hash, not very useful.
You may want to change that to: 
        callback => sub {save($window,$text)},
and eliminate the $widget argument from the callback.

Note that potentially this is a lot of data, so it's better to do 
it in chunks.

See above. ItemFactories do not support additional data in the
callback unless you build an item at a time...
