Hi Krzesimir and Murray,
Thanks, that makes sense. The Animation timeline still doesn't work, but
that's another problem and I'm happy enough chewing away at it. I can achieve
the effect with a BehaviourPath, so I've got something working to leverage off.
I'm possibly being a sucker for punishment, but is there any other
documentation on wrapping C functions apart from the back of the programming
with gtkmm book? I think I need to understand the process a little better.
Ian.

Glib::Value is not nice to use as one might wish. Maybe try
initializing it before:
Glib::Value<float> xdim;
xdim.init (xdim.value_type ());
xdim.set (150.0);
effect->bind("x", xdim);
