Hi again Simon:
Ok, I was reviewing Scintilla implementation for autocompleting, and actually it won't be that easy unless you change ScintillaImpl for ScintillaEx, which is found here:
http://anyedit.cvs.sourceforge.net/anyedit/AnyEditv2/ScintillaEx.cpp?view=markup
and:
http://anyedit.cvs.sourceforge.net/anyedit/AnyEditv2/ScintillaEx.h?view=markup
Then you can use
SetAutoCompletion(true);
in ctextview, which should derive from ScintillaEx instead ScintillaImpl.
The other option is adding ScintillaEx functions to ScintillaImpl, which I can try to do when I have some time, and tell you if it works.
Regards.
