Re: SVG accessibility new issues

Joanie,

My apologies for using your name as a shortcut for the both linux and
Apple.


Joanie DOES think the pointer should be exposed in Linux. This exposure
is in addition to exposure through the computed name.

Furthermore, the pointer *is already being exposed* for SVG elements
with aria-labelledby. Joanie fixed that bug (along with some parallel
issues) upstream a couple of weeks ago:
https://trac.webkit.org/changeset/198254.

Are any sections/testable statements in the wiki are wrong given your fix?
(Not including stuff that is still an open issue).


We have an agenda issue for Wednesday

Difference between testable statements in wiki and spec
Webkit doesn't follow the spec for name - the spec has requirements for
exposing labelledby, webkit doesn't bother - neither linux (Joanie) or
apple see a current need for exposing labelledby
https://lists.w3.org/Archives/Public/public-svg-a11y/2016Mar/0049.html
Rich filed a bug on my request and if we agree labelledby doesn't need to
be expose we need to remove the bug

It sounds like linux (Joanie) follows the spec but apple doesn't - is this
correct?  What would a better description of the issue be? How about?

Hey Fred, all.

Some clarifications regarding this item:

Joanie doesn't see any point to exposing a pointer via AXTitleUIElement
in the case of OS X if Apple doesn't see the need, VoiceOver doesn't do
the wrong thing without this pointer, etc. It's Apple's platform; not
Joanie's. And Joanie respects that. :) And the labelledby value IS
exposed through the computed name (aka AXDescription).

is in addition to exposure through the computed name.

For those of you who like layout tests (who doesn't love layout tests?):
If you look at
https://trac.webkit.org/browser/trunk/LayoutTests/platform/gtk/accessibility/w3c-svg-name-calculation-expected.txt#L1
,
you'll notice a bunch of "AXTitleUIElement: non-null" lines (In the case
of Linux, "AXTitleUIElement" is layout-test speak for "the object
referenced by ATK_RELATION_LABELLED_BY". Thus that file documents the
fact that WebKit DOES bother for Linux.)

Sorry for any confusion or lack of clarity on this matter in my previous
communications. And please let me know if anything remains unclear.

Thanks!
