Looks good to me!

Only one suggestion: Perhaps move the coreObject->ref() into the GObject itself. Since the object is responsible for the deref(), it makes sense for it to do the ref() as well.

You've exposed addEventListener to the bindings (I think). Is that part of some later work, or required for this patch?

Yeah, I actually planned to do this, but the issue is you cannot know the type of the coreObject in WebKitDOMObject, where that code lives, so you cannot do the casting we do in the wrap method to call ->ref(). On the other hand I don't think that's really needed, I suppose if you cast it to some really low level class where ref/deref are defined it should be more than enough.

I actually didn't, they are blacklisted in CodeGeneratorGObject. I just removed the guards that were there so that the Node wrapper correctly adds its event listeners.

You're right, of course. I don't think there is shared reference counted
class between them. The only approach that I can think of is a vmethod
in the GObject. Not sure if it is worth it here.

This looks very good to me. The only conceptual problem I have is with the property - I don't think we should expose a core object in public API (which a property ends up being). Having said that, I understand it would be difficult to deal with this in another way, and approve of the method. Time for GObject to grow private/protected properties? =)

This needs a bit of updating, removing from the queue.

I have added an updated patch which builds against the latest commit (apart from the constant changing Changelog)

Updated patch. Adds a custom kit method for Event* instead off doing an ad-hoc create_event in Document, it's less code \o/
