Hi David,

Well, I was mostly busy with my snowboard in the French Alps the past 
week :-)  Sorry for not replying earlier.

It is a long-time wish for me to have the scintilla control as part
of wxHaskell and it would be great if someone would do this!
The scintilla editor is really a great tool.

Anyway, I see two problems, uhh, challenges I mean:

1) The component uses its own protocol to call methods
2) The component uses its own protocol to send events

So, first of all, I think it is necessary for you to run
a basic C++ wxWidgets sample with wxScintilla. Next, you need
to somehow make a "C" wrapper (in wxc) for some scintilla methods
and add the signatures to the "wxc.h" header file (so they get
marshalled by wxDirect). Furthermore, I think it would be much
better if you use the wxWidgets standard event model. Actually,
you can see how you can make custom events by looking at the
"wxcHtmlEvent" class in the "wxc/src/extra.cpp" file (this is
all a bit of mess, so carefully navigate aroung :-)

Well, I hope this helps you to get started, feel free to
write to me personally to get more help -- I would really like
to see scintilla as part of wxHaskell.
