Cairo-GObject provides access to enums, but it won't automatically get you great cairo bindings. It might actually get you 90% of the way there, though, and I'd be interested seeing how far you can run with just that, and be happy to merge patches that make it easier.
Why? cairo has a subtype system where you have subtypes of cairo_surface_t (e.g. cairo_image_surface_t) or cairo_pattern_t (e.g. cairo_gradient_pattern_t) where some objects have special methods. You determine which type this is by calling cairo_surface_get_type(); and matching it against a closed enum (cairo_surface_type_t). It might be enough to do 90% of the work with GObject-Introspection and write some small by-hand functions when you need to "cast" to a specific type in your binding, but you do always need some small native glue code that calls cairo_surface_get_type(); On Thu, Jan 22, 2015 at 9:39 AM, Nicola Fontana <n...@entidi.it> wrote: > Il Thu, 22 Jan 2015 16:28:19 +0000 Emmanuele Bassi <eba...@gmail.com> > scrisse: > > > Cairo is not a GObject library, so introspection is fairly useless. > > Hi Emmanuele, > > the cairo source tree includes cairo-gobject [1] that already wraps > enums and structs in GObject style.
