I don't actually remember writing that. So I must guess what I meant.

Even after seeing the C documentation:
http://developer.gnome.org/doc/API/2.0/gdk/gdk-Graphics-Contexts.html#GdkGCValues

I'm still not quite sure what a GdkGCValues does. Is it just for saving
the whole state of a GdkGC, or is it often used to set individual
details.

Maybe we should just use it to implement an operator=() ?

For now, of course, you can use gobj() and use the original C functions.
