> Existing API only provides the information that state has changed. There is no info about the previous state of the element. I guess some little heuristic should be done here to find this element. What do you think ?

If you literally mean "find" that element, I think that's a bad idea -- and an unnecessary one: Given a tri-state checkbox foo, any time foo changes state -- for whatever reason, including bar changing state -- foo itself should notify WebKit that its state has changed. In other words, if bar changes state you should not try to find foo. Foo should come to you with its own web-app-emitted signal.

If, on the other hand, all you are told is "foo changed state to checked/unchecked" and you have no way of knowing if foo might be a tri-state that just lost state mixed/indeterminate.... a) That sucks. ;) b) Determining that foo is tri-state *might* require a heuristic.

Make sense?
