27829 2015-01-14 05:22:35 +0000 [Shadow]: Update ShadowRoot to have elementsFromPoint and caretPositionFromPoint 2015-04-15 06:39:03 +0000 1 1 1 Unclassified WebAppsWG HISTORICAL - Component Model unspecified PC All RESOLVED FIXED P2 normal --- 14978 1 pdr hayato hayato mike public-webapps public-webapps-bugzilla oldest_to_newest 117132 0 pdr 2015-01-14 05:22:35 +0000 cssom-view now has the following extensions to Document[1]: partial interface Document { Element? elementFromPoint(double x, double y); sequence<Element> elementsFromPoint(double x, double y); CaretPosition? caretPositionFromPoint(double x, double y); }; Only elementFromPoint is currently defined on ShadowRoot. The best way forward would be to define this in cssom but, until then, can we add the following methods to ShadowRoot? sequence<Element> elementsFromPoint(double x, double y); CaretPosition? caretPositionFromPoint(double x, double y); They could be defined in roughly the same way as elementFromPoint.

Sounds the spec needs to reflect the change of cssom-view. 117186 2 hayato 2015-01-15 06:09:41 +0000 Instead of defining these in Shadow Root as well as in Document, I've started to feel that it'd be better that we have the common interface between Document and Shadow Root. e.g. interface NodeTreeRoot { Element? elementFromPoint(double x, double y); sequence<Element> elementsFromPoint(double x, double y); CaretPosition? caretPositionFromPoint(double x, double y); Selection? getSelection (); readonly attribute Element? activeElement; readonly attribute StyleSheetList styleSheets; }; Document implements NodeTreeRoot; ShadowRoot implements NodeTreeRoot; 117443 3 pdr 2015-01-22 23:34:06 +0000 @Hayato, that sounds reasonable to me. Can we make it so? :) 117532 4 hayato 2015-01-28 08:41:10 +0000 (In reply to Philip Rogers from comment #3) > @Hayato, that sounds reasonable to me. Can we make it so? :) Yeah, we can do it, however, we have to rewrite each behavior of each API so that it also considers shadow trees as well as the document. That's not so difficult, but let me put this on my task queue for now. 117652 5 hayato 2015-02-02 05:26:05 +0000 Make ShadowRoot have elementsFromPoints and caretPositionFromPoint tentatively at: https://github.com/w3c/webcomponents/commit/3df488859776f0f1cd4a17b5c564cf6165584cb9 In the long term, we should have the common interface between Document and ShadowRoot. 117653 6 hayato 2015-02-02 05:30:45 +0000 I'm aware that these are tentative definitions. However, it would serve the most of our purposes for a while, I hope. 119517 7 hayato 2015-04-15 06:39:03 +0000 Let me close this bug. I've filed a bug for comment #2 as https://www.w3.org/Bugs/Public/show_bug.cgi?id=28493
