Do you really mean "always" here? I haven't done it before. I don't see it 
used in Vasilis's demo either.

This worked, thanks.  Is self being bound to the containing mk-<widget> 
something we can count on?

This turns out to be something that can, and probably should be, done without 
using the clos objects, it is all gtk calls. I added an 
initialize-instance :after method to gtk-app that you can see in the cvs 
repository, cells-gtk/gtk-app.lisp.

Thanks for the help.
