FWIW: after this I wanted to check how can the objc bindings do events without actually exposing any event object/structure directly, since it seemed at best tricky to achieve this (eg, you really need access to some data members of say MouseEvents to make sense of what happened; if it's not exposed as a class in the API it must be exposed in some other way). So checking the code I see some headers in the objc bindings dir where there are references to headers referring to particular event types: WebCore/bindings/objc/DOMEvents.h: (...) #import <WebCore/DOMEvent.h> #import <WebCore/DOMEventException.h> #import <WebCore/DOMEventListener.h> #import <WebCore/DOMEventTarget.h> #import <WebCore/DOMKeyboardEvent.h> #import <WebCore/DOMMouseEvent.h> #import <WebCore/DOMMutationEvent.h> #import <WebCore/DOMOverflowEvent.h> #import <WebCore/DOMUIEvent.h> #import <WebCore/DOMWheelEvent.h> (...) and googling a bit with those names you can see the usual definitions for things like DOMMouseEvent: http://google.com/codesearch/p?hl=en#mc67TWYcYcg/WebKit/DOMMouseEvent.h&q=DOMUIEvent.h&d=1 So if all this stuff is exposed in the API I think what I have done in the GObject bindings is essentially the same, and I'm not really exploring any new ground. I guess at some point we started talking about different things, and you meant something else in your answer?
