"top of the widget root" is weird.  You just mean "the widget" I think.

capital Windows here, to reduce confusion with lowercase windows below

Maybe make it more clear why we expose this?  Maybe the caller doesn't care that
it's an eventbox but rather this is just "the widget that contains the junk" or
whatever.
