23:05:54 <MarkS> hi rio cabanier_, are you available?
23:06:01 <MarkS> s/rio/rik
23:06:03 <Zakim> +cabanier
23:09:11 <MarkS> [discussion on scrollPathIntoView() and why location information of fallback content needs to be updated]
23:11:32 <MarkS> zakim, take up item 2
23:11:32 <Zakim> agendum 2. "scrollPathIntoView()" taken up [from MarkS]
23:13:09 <MarkS> RS: we need to add text that makes it clear that scrolling the page (and moving the position of canvas objects in the browser window) should result in location information updates to fallback elements as well.
23:14:37 <MarkS> JMunro: We should probably add that under point #3 Scroll rendered fallback element into view with the align to top flag set.
23:15:11 <MarkS> RC: Sounds like advice.  Do we need to put it here?
23:15:25 <MarkS> RS: Should probably go in an implementation guide for Canvas
23:16:03 <MarkS> RC: I don't think we need to specify that the position of the elements gets changed if the page scrolls.
23:16:46 <MarkS> ...If the canvas document is offscreen and an element gets focused, it should tell the browser to move the canvas into the viewport
23:17:21 <MarkS> RS: just need to put something into the method for scrollPathIntoView()
23:17:39 <MarkS> ...and this was moved to L2
23:17:51 <MarkS> RC: Should we leave it undefined for now?
23:18:26 <MarkS> RC: if you are tabbing to an element that is offscreen, you want to scroll the page to move it into the viewport
23:18:30 <MarkS> RS: Where should that go?
23:18:40 <MarkS> RC: It should be text that is similar to scrollPathIntoView
23:18:57 <MarkS> ...it should be one of the steps for drawing the focus ring
23:19:46 <MarkS> JMunro: I'm wondering if sending location updates to the a11y layer is really needed because its connected to the fallback content which is connected to the element drawn on the screen.
23:19:55 <MarkS> ...do we need a note that says to move the location too
23:20:36 <MarkS> RS: If you tab to something which is a fallback content, what would happen?
23:21:19 <MarkS> JMunro: I think the browser would move focus to that element, and draw the focus ring.
23:21:31 <MarkS> RS: When you first tab, will you have a location?
23:21:55 <MarkS> RC: the position is always known.
23:22:11 <MarkS> ...when you call drawFocusRing, you set the location
23:23:09 <MarkS> RS: before that is called, we don't have location information.
23:23:09 <MarkS> RC: that is true
23:23:35 <MarkS> ...but they have to call drawFocusRing, even when it does not receive focus (its just checking)
23:25:11 <MarkS> ...I don't think we need to define this behavior
23:25:58 <MarkS> JMunro: I thought location information for all elements was only returned on dCFR
23:26:10 <MarkS> ...dSFR returns VOID
23:27:12 <MarkS> JMunro: so element.focus doesn't trigger this, they have to call drawFocusRing
23:27:22 <MarkS> RC: correct.
23:28:01 <MarkS> ...author needs to call drawFocusRing which checks all the canvas elements to see if it has focus.  if it does, it draws a ring, regardless it will update the location info for all elements in canvas
23:28:39 <MarkS> http://www.w3.org/html/wg/drafts/2dcontext/html5_canvas_CR/#dom-context-2d-scrollpathintoview
23:31:37 <MarkS> RC: We need additional text under scrollPathIntoView() "if the elements region is not on the screen, then scroll the region into view"
23:33:53 <MarkS> JMunro: RE: where to put these things. Do we want to put these notes at the bottom of both methods (dCFR and dSFR)
23:34:36 <MarkS> RC: It should be after step 1 of each function
23:34:44 <MarkS> s/function/method
23:35:37 <MarkS> RS: This is something they would have to change in Chrome...
23:35:39 <MarkS> RC: yes
23:35:45 <MarkS> ...should talk to Dominic
23:38:24 <MarkS> JMunro: I can put some draft text into there that clarifies that if focus is moved to an element on the canvas and the canvas is not in the viewport, the page should scroll so that the canvas is in the viewport.
23:38:52 <MarkS> RS: I just pinged dominic and he said no problem.
23:39:35 <MarkS> zakim, agenda?
23:39:35 <Zakim> I see 5 items remaining on the agenda:
23:39:36 <Zakim> 1. Review action items taken up at last meeting [from MarkS]
23:39:36 <Zakim> 2. scrollPathIntoView() [from MarkS]
23:39:36 <Zakim> 3. Continue Bug Walkthrough (starting with 23980) [from MarkS]
23:39:36 <Zakim> 4. Estimate how long it will take to address rest of the bugs [from MarkS]
23:39:36 <Zakim> 5. Confirm next meeting [from MarkS]
23:40:11 <MarkS> RC: after step 3, when the elements are attached to the region. that is where it should go
23:41:02 <MarkS> zakim, take up next item
23:41:02 <Zakim> agendum 1. "Review action items taken up at last meeting" taken up [from MarkS]
23:41:58 <MarkS> JMunro: 23978 is mostly taken care of.  I see your reply now and will finish it up.
23:42:39 <MarkS> ...wanted to suggest that as we make changes, can we say something like "change [original content] to [new content]"
23:43:09 <MarkS> RS: absolutely
23:44:52 <MarkS> JMunro: we can make changes to L2
23:45:13 <MarkS> http://www.w3.org/WAI/PF/HTML/track/actions/224
23:46:46 <MarkS> RS: That is all taken care of.  There may not be a bug, but the work is being done
23:46:55 <MarkS> MS: I can take a closer look to confirm.
23:47:05 <MarkS> zakim, next item
23:47:05 <Zakim> agendum 3. "Continue Bug Walkthrough (starting with 23980)" taken up [from MarkS]
23:47:21 <MarkS> https://www.w3.org/Bugs/Public/show_bug.cgi?id=23980
23:48:02 <MarkS> RC: we agreed last call that dSFR is OK dCFR needs work, but we can do that for L2
23:48:20 <MarkS> JMunro: Let's make a note on the bug.
23:48:32 <MarkS> https://www.w3.org/Bugs/Public/show_bug.cgi?id=23982
23:49:00 <MarkS> Focus Ring out of canvas
23:49:55 <MarkS> RC: I think that was a question from Apple.  Wanted to know what should happen
23:50:20 <MarkS> ...what happens when you try to scroll to it.
23:50:39 <MarkS> RS: the location would change, but the visual rendering of the ring would be clipped
23:50:45 <MarkS> ...do we need a note to clarify that?
23:51:51 <MarkS> RC: lets say the path is underneath the canvas element, would you scroll past that, or to the bottom or not at all?
23:53:09 <MarkS> ...clip it if its partially visible, but what if it is not visible (beyond the canvas borders)
23:53:44 <MarkS> ... wouldn't you just say abort
23:55:41 <MarkS> RS: give it a location, but don't draw anything.
23:56:12 <MarkS> RC: what happens if you tab to the fallback content for an element that is rendered beyond the borders of the canvas?
23:56:27 <MarkS> RS: don't scroll at all.
23:56:41 <MarkS> ...it has to be visible on the canvas
23:57:10 <MarkS> RC: so that should be made clear.  if the element is beyond the borders of the canvas, do not scroll it into view
23:57:47 <MarkS> zakim, next item
