If by “PageClient” you mean the WKPageLoaderClient in WKPage.h, then didCommitLoadForFrame is there. I don’t even recall there ever being a didCommitLoadForMainFrame, but didCommitLoadForFrame combined with a quick call to WKPageGetMainFrame will do the exact same thing. > WebPage does have a callback that tells this (didStartPageTransition), but > this is not forwarded to UIProcess, which is kind of weird, since its > opposite (didCompletePageTransition) is fired to PageClient when a page has > completed its transition. didStartPageTransition is about starting a provisional load, and didCompletePageTransition is *not* about committing a provisional load. Additionally, neither of these are actually sent to any API clients; They are internal to WebPage. If you think didCommitLoadForFrame() for the main frame was what you wanted, then both of these are irrelevant anyways. > I have a patch that does forward the didPageStartTransition to UIProcess and > I would like to know what you guys think of that. Does this seems useful to > you as well? Since - at this point in my response - I’m not sure what you want or what you’re talking about, I would say no it does not seem useful. ~Brady
