Hi James,
   This list is for general questions about gtk+, usually that means
support for people trying to compile or use the gtk+ api, might
I suggest you send this mail to gtk-devel-list gnome org, which is
about the development of the gtk+ libraries.

FWIW, I think that what you've done is a really great idea - IMO
widgets should be as simplistic as possible and combinations of
entries/spinners should be done in more high-level "composite
widgets" - great idea... however the fact that we already have
a GtkSpinButton that exists and has a public API that 
"cannot be broken" may mean that we cant take advantage of such
a redesign/refactoring... 

One question I'd have to put to you: Do you think its possible
with the code you've written to make the existing GtkSpinButton
use your spinner instead... without breaking the existing
spinbutton api ?

Anyway, try sending this mail to the gtk+ development list - I'm
curious to see what they have to say on the matter ;-)

Cheers,
