I think you want to just return nil

[Tim Horton]

ALSO, don't you need to get mouse events when you're inside the HUD? It looks like WKPDFHudView implements mouseDown.

[Tim Horton]

So probably what you really want is to return nil UNLESS the point is inside _layer, in which case you return self.

(And also only if the layer is not hidden, but I think it always will be unhidden if the mouse is over it??)

[Alex Christensen]

WebViewImpl::mouseDown and friends give all HUDs the needed mouse events, not just this one, which is better than what you suggested because there may be two partially overlapping HUDs.

[Tim Horton]

Oh! So it’s called by WebKit code, not appkit? Very confusing!
