- Travis_MSFT: I think we can probably combine the discussion on DOM 3 Events with UI Events

- 01:40:16 [wangxz]
- wangxz has joined #webapps
- 01:40:16 [heycam]

- 01:51:03 [heycam]
- ... after that, Marcos from Mozilla proposed we align our efforts with Service Workers
- 01:51:17 [heycam]

- 01:51:18 [heycam]

- 02:09:09 [heycam]
- ... there's some thinking around multiple users using a common application,
- 02:09:09 [heycam]
- ... and if there's more than one keyboard device provided, you might want to take presses from different places
- 02:09:10 [heycam]
- ... gamepad takes a simpler model

- gary: with buttons, we wanted that to happen

- ... e.g. click events to fire for buttons
- 02:09:11 [heycam]
- ... a recent change in DOM 3 click and dblclick events are fired only for the primary button
- 02:09:11 [heycam]
- ... so that doesn't work for gamepad, with a dozen buttons

- 02:11:53 [heycam]
- ... don't know if that's important
- 02:12:35 [heycam]
- chaals: the general principle is, if you change the spec between FPWD and LCWD, when you CfE again at last call, people may exclude patents against the new bits of work
- 02:12:35 [heycam]
- ... whether that happens or not...
- 02:12:35 [heycam]

- 04:23:56 [bryan]
- sicking: our keyboard API addresses a very different use case; it does not allow a webapp to build its own IME, rather for an app to be the IME for other web pages
- 04:24:34 [bryan]
- ... there are some APIs on some platforms that allow apps to act as IMEs, in the web platform we had to build a new API for that
- 04:25:06 [bryan]
- kochi: so you mean providing IME by the platform and providing IME for specific webapps is different
- 04:25:55 [bryan]

- … now looking at using Media Queries
- 05:42:12 [jcraig]
- "Because this approach relies so heavily on features that overlap with work maintained by the CSS Working Group and Web Applications Working Group, it is likely that portions or all of this specification may move under the purview these other groups.

- JS: we met with CSS WG today
- 05:48:39 [abarsto]
- … they will look at our spec and give us feedback
- 05:48:56 [jcraig]
- When the author first attempts to check the 'matches' property of the query, the user agent will determine that this is a restricted setting, and immediately return false, so the first call to this function on the initial page load will never result in audio descriptions being enabled.
- 05:49:01 [abarsto]
- Gary: re D3E, wondering about fingerprinting and keyboard layout
- 05:49:07 [jcraig]
- Note: The immediate return is critical to prevent blocking threads, as well as eliminating potential abuse by fingerprinting scripts attempting to determine uniqueness using execution time of the synchronous call to mql.matches.
- 05:49:16 [jcraig]
- However, at the same time, the user will be prompted to decide whether or not to share their media alternative settings with the requesting web site.
- 05:49:22 [abarsto]
- … we need to support customized keyboards
- 05:49:25 [jcraig]
- The web author can register for a change listener on this media query list, and the event handler will be called asynchronously when the user agrees to share their media settings.
- 05:49:29 [abarsto]
- … need some UX for that
- 05:49:44 [abarsto]
- … We should talk with you in the D3E context
- 05:50:01 [abarsto]
- CN: not sure this effectively solves the fingerprinting prob
- 05:50:18 [jcraig]
- When the user prompted, matchMedia returns false (or default value) immediately, and only provides the updated match asynchronously through matchMedia().addEventListener or subsequent requests to matchMedia().matches (e.g. on page reload) so there is never any detectable difference between "No" and "You don't need to know."
- 05:50:23 [abarsto]
- … my concern is that you have uninformed and no consent
- 05:50:30 [abarsto]
- … forces user to give consent
- 05:50:33 [jcraig]
- A restricted @media block never prompts the user unless both the @media block and an included selector matches.

- 05:53:06 [jcraig]
- When we spoke with CSS, they agreed that some of these media features made sense, but the privacy/restriction model may be outside the scope of CSS WG. We think its within the scope of WebApps…
- 05:53:21 [abarsto]
- … not sure it is quite so clear

- 05:53:46 [abarsto]
- CN: not about acceptable or not
- 05:54:00 [abarsto]
- … but saying it will protect your privacy is overselling
- 05:54:03 [jcraig]
- The other aspect about this that I'd like to bring to the WG's attention is currently a todo in the draft:
- 05:54:10 [abarsto]
- … don't see it as an impasse
- 05:54:22 [abarsto]
- … but if the privacy system doesn't protect privacy
- 05:54:28 [jcraig]
- Add justification interface on a per-category setting (possibly meta tag or a partial interface on document). Justification string may be defined by an new JavaScript interface, or perhaps by a meta tag in the document head, such as:
- 05:54:28 [jcraig]
- <meta name="userMediaSettings" content="Used to enable captions and display them in your preferred font size and color.">
- 05:54:39 [abarsto]
- … need to recognize their are implications of providing more info
- 05:54:40 [jcraig]

- ... previously you could tell which physical key was pressed - cannot do this with key event in DOM3
- 06:19:51 [adrianba]

- gary: you're wondering when we're likely to get rid of keychar and keycode?
- 06:22:44 [adrianba]
- ... they will live as long as web sites need them to be around - we need a good spec to replace them

- 06:23:38 [annevk]
- garykac: so that seems kinda contrary to how we define many features

- 06:28:44 [adrianba]
- chaals: known issue at W3C of having specs out of sync
- 06:29:01 [adrianba]
- ... sounds like the sensible thing is to look at the modern spec and use it as your working reference
- 06:29:15 [adrianba]
- ... if you run into trouble you can consider process hoops for changing reference
- 06:29:29 [richardschwerdtfeger]
- Rich: what is "modern"?
- 06:29:35 [adrianba]
- ... but now it is more common to publish Rec based on draft spec if the part you depend on is stable enough
- 06:30:06 [adrianba]
- gary: considering UI Events was primary given constructors and code attribute
- 06:30:21 [adrianba]
- ... it was a dumping ground for feautures we didn't think would make it into D3E
- 06:30:28 [adrianba]

- [UIEvents is more modern than DOM3, DOM4 is more modern again, If I got it right...]

- 06:33:54 [garykac]
- Once we move |code| into DOM3, then DOM3 will have a complete KeyboardEvent specification

- ... previous api was only implemented by chrome - would like to get more support from other browser vendors on new version

- … it's writeable in the intereface and setting it when the reaonly flag is set will throw.
- 09:48:51 [chaals]

- DS: Don't have dictionaries
- 09:59:34 [chaals]
- AvK: Doesn't matter
- 09:59:41 [chaals]
- Cam: That would be the WebIDL way to do this.
- 10:00:06 [chaals]
- … If we make a @@@@@ for an unchanging object, you can use the dictionary version to get.
- 10:00:17 [chaals]
- … We don't want to have a new version changing values all the time.

- Alex: By default WebIDL uses getters/setters, whereas javascript uses properties. Seems Anne was saying start with the obvious thing from ajvascript.
- 10:01:30 [chaals]
- … not clear that the base class and then setting a flag to force readonly, is a good way. Not natural in Javascript.

- Trav: Getter argument is that the platform should not update a data value from underneath the JS code. If the value of a property is 5, it shouldn't change to 6 without you knowing.
- 10:02:58 [chaals]
- … for that you have tohave an accessor. DOM attributes are that way, but makes sense that the workd is oriented to getters/setters.
- 10:03:10 [Daniel_Austin]
- +1 readonly descends from readable/writeable
- 10:03:16 [chaals]
- AR: But the single point of truth being the object seems like a broken assumption
- 10:03:34 [chaals]
- JS: Problem is talking about a wide range of objects - lots of different behaviours.

- 10:03:52 [chaals]
- … many objects returning would not make sense with data properties.
- 10:04:12 [chaals]
- … seems in many cases but not all getters make sense. Maybe not as often as we use them.
- 10:04:37 [chaals]
- … Exception objects are one of the few objects with properties, and had getters. That'sthe pattern, but people don't use them much.
- 10:04:59 [chaals]
- … If we can return dictionary objects, inertia is why we keep using interfaces everywhere.
- 10:05:31 [chaals]
- Cam: With objects, you use a different construct to get data properties instead of accessors. You can't have a data property without devolving to prose.
- 10:05:40 [chaals]
- … Makes sense to use a data property...
- 10:06:22 [chaals]
- Alex: What's behind the curtain. If there is an IDL that claims to say what there is in JS, that doesn't seem to hold. But if there is a value where JS isn't privy to it, that would not be a fair assumption.
- 10:06:48 [chaals]
- Cam: If functions that implement getters/setters have access to other properties...
- 10:06:53 [chaals]
- Alex: What are they?

- … so they aren't all that rettible. So there are elements where it makes sense.
- 10:08:36 [chaals]
- Alex: Sure. But to implement a class for this I would only have getters/setters as an exceptional process.
- 10:08:43 [chaals]
- … would support @@@@@@@
- 10:09:05 [slightlyoff]
- ...adding properties to itnerfaces in WebIDL
- 10:09:12 [chaals]
- Cam: For these objects, data properties are more liekly to make sense that things in the DOM that need to do computation or return non-simple values.

- [should we keep going...?]
- 10:11:14 [chaals]
- JS: Seems like if we are going with getters and setters, inheritance is the way to go, but think we're not looking closely enough at using data properties instead.
- 10:11:34 [chaals]
- … Don't know for the specific case of Rectangles.
- 10:12:05 [chaals]
- Cam: Think the proposal was to have both the dictionary and the data properties.
