Description Rick Byers 2015-07-10 12:31:48 PDT
Concrete proposal here: https://github.com/RByers/InputDevice

We're close to doing an intent-to-ship for this in blink, so it would be great to get a better understanding of whether WebKit has any interest in this API or has any outstanding concerns before we ship it.

Seams reasonable. What working group is this work slated for?
Comment 2 Rick Byers 2015-07-10 20:00:09 PDT
Thanks!  I've been talking with WebApps (on www-dom), one of the UI Events spec editors have expressed support (https://lists.w3.org/Archives/Public/www-dom/2015JanMar/0117.html).  UI Events certainly seems like the right place.  But I haven't yet been able to get any further than that yet.  I suspect we won't block shipping on the politics here (but would, of course, block if there are unresolved technical concerns with the API).

Thank you for filing the bug!

The spec appears to be mostly about touch/mouse events at this time, and it is also quite extensible for other event types. Do you have future extension directions in mind?

There is already a note alluding to complexities with keyboard events, and it seems likely that the complexities will grow as use cases and various virtual input devices are considered.
Comment 4 Rick Byers 2015-07-11 03:32:24 PDT
Yes, there has been some brainstorming in the community about how we might want to extend this over time.  Some ideas here: https://docs.google.com/document/d/1WLadG2dn4vlCewOmUtUEoRsThiptC7Ox28CRmYUn8Uw/edit#.  But as you say, the details can get complex, so I figure it's best to iterate incrementally in a careful scenario-driven fashion rather than go nuts all at once.

My focus right now is to solve one particular long standing problem for devices with both a mouse and touchscreen (so not itself that interesting for WebKit).  But no one wants to make one-off hacks just for that, so we're trying to establish a reasonable device info pattern for the future.

Mass move bugs into the DOM component.
