All my #WebKit merge requests have been merged. Now #WebKitGTK supports touch PointerEvent API, touch point coordinates are fractional, synthesized mouse events are unbroken and both WebKitGTK and WPE WebKit handle pointer capture and release according to the spec. This should considerably improve compatibility of #Epiphany (#GNOME Web) with touch interfaces.
There are still some more things to fix in there, maybe someone in #mobilelinux #linuxmobile community would like to give it a try?
Despite of its enormous codebase it wasn't that hard to look around and find relevant stuff - the GTK layer is fairly thin. The hardest part was to compile it, but running distcc on a Steam Deck sped it up well 😄
We still need to:
- emit pointercancel when the browser takes the touch gesture over
- not change scrolling targets during scrolling just because a new one "flew" onto the cursor/finger
- have some thresholds to differentiate between vertical and horizontal scrolling
