That would be great! :) Meanwhile I'm tempted to take another shot at a
decent GUI interface. A direct Qt wrapper for Q would be quite useful.

BTW, if you're interested in database interfaces, then you should maybe
take a look at the code of q-sqlite3. I know that OODBs are different,
but q-sqlite3 might give you a couple of ideas on how to handle result
sets and callbacks into the Q interpreter.

http://www.libsdl.org seems to work ok over here.

q-opengl is rather complex, with all the callback and special
typemapping stuff, but you might wish to take a look at the Makefile to
get an idea how to set up compilation of a q-swig module. I'd suggest
that you first take a look at the basic q-swig example in
/usr/share/q/examples/swig. And then there's a bunch of additional
introductory examples in the swig-1.3.22-q-20060225.tar.gz tarball at
SWIG-1.3.22/Examples/q. It should also be useful to have a look at the
html documenation for SWIG 1.3.22 which is also in that tarball.

I really have to write an introduction to Q-SWIG sometime, but I hope
that with the SWIG docs and the Q examples you'll be able to find your
way. ;-) Of course you could also use Q's "raw" C interface, which is
documented fairly well in the manual, but SWIG is really the only
practical option for wrapping bigger libs.

Cheers,
Albert
