I'm using the C interface ( or better, C++, just #include <SWI-cpp.h> ) to
host the runtime, i.e. swipl.so on Unix or swipl.dll on Windows, in a Qt
text editor.

The tricky part, that I had some hard time to get working, is about leaving
IO unchanged and getting threads attached to Qt from Prolog side ( it's
working now, kind of ).
Now I'm working on the swipl-win interface, controlled from a Prolog script.
The editor, debugger, etc keep running on XPCE.

About completion, I think Jan will publish a PL_... C interface that will
give more sensible hints, by means of inner access to REPL context.
To be true, also the already available (but I don't know how to properly
access it) tab completion is far smarter than my code, that simply caches
the result of this:

?- setof(P,M^A^(current_predicate(M:P/A), \+sub_atom(P,0,1,_,$)), L).

Working on XPCE seem reasonable to me. I'd like to try to reuse XPCE
interfaces in Qt. Could we meet in between ?

This week ( I hope :) I'll upload to github the alpha release of swipl-win
interface, to evaluate deployment feasibility.
Since Qt is evolving, it's kind of experimental work.
