Re: [webkit-dev] new -webkit-user-select value: atomic
Hi, After reviewing the original specification for 'user-select: all' [1], I think the behavior we had in mind for 'user-select: atomic' matches the original intent of 'user-select: all'. It also partially matches the Mozilla behavior, and I believe the differences are likely to be bugs in Mozilla's implementation. I've encouraged Alice to proceed with implementing, using 'all' for the property value, while we continue to work the issue in the CSS WG. Thanks, Ted ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo/webkit-dev

Excellent! Thanks for the follow up. I'm so glad we reached out to the standards group first. - Ryosuke On Aug 7, 2012 2:31 PM, Edward O'Connor eocon...@apple.com wrote: Hi, After reviewing the original specification for 'user-select: all' [1], I think the behavior we had in mind for 'user-select: atomic' matches the original intent of 'user-select: all'.

[webkit-dev] new -webkit-user-select value: atomic
We intend to work on an experimental implementation of a new -webkit-user-select value that we are calling atomic. This value causes the element to which it is applied to behave atomically for selection purposes; either all of none of the element and its contents are contained in the selection. The user-select property is not currently specified in any CSS specification, but we intend to start discussion on www-style. Firefox implements this property (prefixed with -moz). They have a value, all, that superficially behaves like atomic, but has some different behavior under incremental selection, which is why we're not using that value. Since the property name is prefixed, we don't intend to prefix the new value. Alice ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo/webkit-dev

Could you give us an example of how this properly might be used? The user-select property is not currently specified in any CSS specification, but we intend to start discussion on www-style. Yes! Given that IE10 now supports -ms-user-select, it is imperative that we spec this property in the CSS working group. Firefox implements this property (prefixed with -moz). They have a value, all, that superficially behaves like atomic, but has some different behavior under incremental selection, which is why we're not using that value. Could you elaborate more on the difference? Maybe the difference is small enough that it makes sense to reuse all. e.g. Mozilla might be willing to change their behavior for all. - Ryosuke ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo/webkit-dev

We'll try to work quickly to reach consensus in the WG. /be ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo/webkit-dev

Thanks for the follow up :) Yeah, I'm quite concerned about adding even more values to this completely under-speced CSS property as well. We're already divergent on some aspects of none (see https://bugs.webkit.org/show_bug.cgi?id=82692 and https://bugs.webkit.org/show_bug.cgi?id=80159), and I would love to see some progress in the CSS WG before we proceed with the implementation of this new value (would be fine if the consensus was to add a new value; I just want to make sure other browser vendors are well informed). - Ryosuke ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo/webkit-dev
