Bug 202789 – [GTK][WPE] Support Pointer Events

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Carlos Alberto Lopez Perez]

Pointer events is a W3C/HTML5 API:

https://developer.mozilla.org/en-US/docs/Web/API/Pointer_events
https://w3c.github.io/pointerevents/

Support for it on WebKit is currently on development. It has been enabled for Mac in bug 195008

It would be a good idea to enable it as well for GTK/WPE.

[Carlos Alberto Lopez Perez]

I have put here some basic demos about this API: https://people.igalia.com/clopez/wkbug/pointer-events/

Support for it can be enabled for GTK and WPE and it works, but currently it only works with pointerType=mouse. If a touch device is present, it doesn't work as expected (no pressure report,etc) and it reports the pointerType as mouse.

I think we can enable this as an experimental feature for the meantime. It should not be promoted to be enabled by default until it can fully replace the alternative API (MouseEvent+TouchEvent)
