Ah, i was clicking autofile after i had made a gradient. I understand now.

I havn't tried using it for anything real. i was mostly playing with the
interface. I think your example of including it above is the way to go. As
for MAX_GRADIENT_ITEMS and using an array, why not use std::vector? i'm
assuming, perhaps wrongly, that you are using C++ (I'm under the impression
that wxWidgets is a C++ toolkit)

Overall, I think it looks good.
