Thanks for all the info - that's really useful! I've printed it out, and am 
using it as a reference while I try and puzzle out how to adapt to smoke code 
for ruby. Sorry I've taken so long to reply, but I've only just got round to 
doing anything.

So far, so good. I read up on the ruby C interface for the stuff in ruby.h, 
and reminded myself how the existing Qt 2 ruby bindings work. The ruby 
interface is much simpler (and prettier?), than the perl .xs one. I think 
getting to grips with Qt.xs is going to take the longest - I feel on top of 
most of the rest now.

I've built the smoke lib from the KDE cvs - I needed to remove qt_x11.h from 
the header list though as it wasn't in my current qt-copy/include directory. 
And I'm using PerlQt-3.006 downloaded from SourceForge with it - I didn't 
realise there wasn't any perlqt in the cvs. I needed to use the KDE cvs 
kalyptus and smoke, otherwise I got an error about QTextItem being missing as 
it's changed to a private class.
