There are not too many things you can do when
you are working with an interactive program. I
could, of course, give you a place to write the
filename you want, but that is nearly as tedious
as, well, writing it the way you are doing it now. :-)
Still, you do have this control already, because
it is possible to ask cgWindow to output the
contents of the window independently of the window. And,
of course, you can specify the name of the output
file when you do so:
cgControl, OUTPUT='whateveryoulike.png'
I do store the name of the *last* file you interacted with
with cgPickfile (presumably, in this case, the last file
you wrote if you are only working with one window at a time)
and I could retrieve the basename of that file and use it.
There will be errors from time to time if you are using
cgPickfile for other things.
I could also (but this is a LOT more work and I have
a full-time job now) allow you to suggest a name for
the output file and use that. That may, in time, become
just as tedious as the current solution, and it is
certain to complicate the code a great deal. It doesn't
immediately jump out at me as the "right thing to do".
In this case, I don't see a clear way forward. I wonder
if anyone else has a good idea?
Cheers,
David
