Bug 139071 – AX: [ATK] Inline text elements with accessible object attributes and/or event handlers are not exposed

• Component: Accessibility
• Status: RESOLVED FIXED

[Joanmarie Diggs]

ATK fails to expose inline text elements which have accessible object attributes and/or event handlers. Examples:

* span with an onclick handler
* abbr with a title attribute
* time with a datetime attribute

These need to be separate accessible objects. The appropriate role is ATK_ROLE_STATIC, which was added to ATK v2.15.2.

Note that the "expected" UNKNOWN roles are due to the need to bump the minimum ATK version in the GTK -- and EFL if they want to -- jhbuild. See bug 139070. In the meantime, this patch demonstrates that the inline text elements are now being exposed (albeit with a less-than-ideal role).

Chris, when you get a chance, could you please review this? Thanks!

Can we make the time element accessible on its own so we don't need to check date time in the list of attributes to check against all elements? InlineRole is a bit of a strange name. I don't have a better idea though.

Makes sense.

Related aside, that attribute also applies to <ins> and <del>. And if there is value in exposing datetime for <time> for ATs (which I gather from Steve Faulkner and others there is), I assume that value also applies to modification-related elements. So I made time + ins + del accessible on their own. (And also created a couple more roles-exposed.html items to test those.)

I gave it more thought today, and I'm still at a loss. Hopefully it will not be needed all that often, so if and when a better idea appears it should be simple enough to change.

we can probably just write this as
return hasTagName(insTag) || hasTagName(delTag) || hasTagName(timeTag)
