[WK2][GTK] Propagate motion-notify-event signals from the WebView

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Mario Sanchez Prada]

As it was brought up in the mailing list recently[1], there are some signals for which the default handlers in the WebView prevent them from being propagated as there is no way to know, in a multi-process model, when the WebProcess have actually processed them or not (they should be propagated when not processed). See more detailed explanation in [2].

Options proposed were, mainly, to either store the event in the UI process and re-emit later once we know the Web process has not been handled (as done for key events) or simply to return FALSE to always propagate them, which sounds like a good option for events like motion-event-notify, which do not act over any specific target (see [3] for a better explanation of the rationale behind).

I discussed this with Carlos on IRC and he agrees on doing that change for motion events, so tracking that change here.
