Adding reviewers to get some more perspectives on this. The description is missing in the PR, but the relevant discussion is in #1440, and I think the idea is sound. |

@smhigley I updated the property description to move this along. Nearly ready IMO. Some comments in the diff. |

I think we need a discussion of whether aria-actions should be allowed on elements that are not focusable or referenced by aria-activedescendant. I see potentially big problems with elements that are containers with boundaries that screen readers treat as invisible. I also am concerned about the idea that it could be used on a dialog, which by default, should not be focusable; that is only a fall-back error condition where a dialog would get focus.
I have added several suggestions where I think the language needs more clarity.

I propose we remove the phrase indicating that aria-actions would be used to associate a dialog element to its close button. We need discussion about that specific use case. I think that is a potentially problematic idea.
If the property definition is going to include a phrase that starts with "such as" or "for example", I propose that such a phrase be more clear and concise.
Here's my suggestion:
| <p><a>Identifies</a> a related element or elements whose primary activation (<code>click</code> event) will trigger a behavior or operation relevant to the referencing user interface object, such as the close button for a dialog, or a reply button relevant to the specific email message in focus.</p> | |

What is problematic about it? Users should be able to close a dialog by pressing the escape key (or platform-specific dismiss trigger like VO's scrub), or navigating to a activating the close button, so what's wrong with another way to trigger that?

I propose the following to:
- remove other potentially confusing uses of the term "current element".
- Provide more clarity about the benefits and expected assistive technology support.

Why is this a "SHOULD" instead of a "MUST"?
The "focus" aspect of this requirement should specifically address active descendant in a way that is consistent with how we do so elsewhere.

Mainly because an author cannot detect all forms of AT focus, so there is no way to achieve a MUST. But also to avoid overly restrictive UI flexibility. Authors may have good reasons for not doing this, so we should not penalize them with a validation error.
Since you addressed the active descendant in a later thread, let's continue that discussion there.

Re: Matt's suggestion of
+ or when the referencing element is referenced by <sref>aria-activedescendant</sref> from an element that has DOM focus.IMO, this change will reduce the clarity of the intention and complicate the implementation... In this scenario, it's okay for the container element to manage these actions rather than the activedescendant. Chaining an action through an activedescendant has no precedence on any platform I'm aware of.

Authors should not be able to detect the presence of AT or any form of AT focus. I think we should remove the phrase "focused by assistive technology" from the definition. AFAIK, we have not defined assistive technology focus and do not use it elsewhere in the spec.
I don't quite understand how this would work without mapping actions to elements referenced by aria-activedescendant. Consider a listbox or tree implemented with aria-activedescendant. If there is going to be a custom action on each option or treeitem, the option or treeitem will not have DOM focus; it will be referenced by aria-activedescendant.

I think there are some potential author musts here.
If the focus is from the UA, then any aria-actions must be visible.
In fact, if the element with aria-actions is visible, then all of it's aria-actions elements must also be visible.

Would folks generally be in favor of removing "or assistive technology" and make it a "MUST", making the entire sentence read as follows?:
Authors MUST ensure that related actions elements are visible and activatable when the current element is focused by the user agent.

To what extent is avoiding creating additional vectors for the active finger printing mentioned in section 11 a consideration in the design of this feature? I see some language that appears to be aimed in that direction, such as the requirement for using clicks and default actions. However, as written, it appears to me that it is all author responsibility, and is thus a wide open door. I wonder if it would be possible to have requirements that:
|
|
Matt, why do we need the focusable rule? Would it not be enough for the source to be visible, and the target to be visible & clickable? To activate the action, the browser can send it a click as if a real mouse click occurred. |
I think you may misunderstand. If an author doesn't use a click, it won't reveal anything new about the user. The UI just may not work in some scenarios. We purposefully limited AT's trigger-ability here to a click (rather than a new event or direct API call) to avoid risk of detection. |
Those are all much too rigid/restrictive in my opinion. And possibly too screenreader specific. AT focus or focus-in is an expectation, but not DOM focus. Otherwise we may not be able to make this work well for other AT like Switch Control, Voice Control, etc. Likewise Dragon on Windows, Android's Switch Access, etc. |

Are there any open questions with this functionality that needs any help? |
|
What else is needed to get this PR merged? |

Ah yup, I meant to do Property: AriaProperties.actions: <value>, thanks for catching that!
It came up in discussions with NVDA & JAWS -- it's definitely not as important as the IAccessibleActions pattern or the AccessibleActions custom property, but folks on those calls said it could be useful as a quick way to check if actions are intended to exist for a given node.
I'm not super opinionated on this one, and we can bring it up again to ask if it's needed.

In conversations today I remembered another reason for this -- it should in theory allow for the possibility to query whether an element has actions even when those actions are not present in the DOM.
I think the issue with that approach is that authors also might not pass in id values when the elements they refer to are not rendered. I'm now wondering if we should treat the presence of the aria-actions attribute, even if set to the empty string, as meaningful or indicative of an element supporting actions even if they are not currently rendered.
WDYT? In theory perhaps the interface mapping with an empty array could also indicate that, and maybe this whole idea is too over-engineered 😅

Do we definitely need to expose the fact that actions exist when they aren't currently rendered?
There was a problem hiding this comment.
I don't think so. What can a screen reader user begin with emty actions?
There was a problem hiding this comment.
@MarioBatusic the idea is that the actions will exist when the control gains focus (or hover, usually), but may not exist before then. If a screen reader user is browsing with virtual cursor and doesn't have focus following the cursor, this mapping would make it possible to still let them know that actions exist. If they attempt to interact with those actions, the screen reader would focus on the control, thus presumably causing the actions to render.

@jcsteh I updated the mapping to be an empty string rather than the value, as we discussed at TPAC. WDYT?
Also if anyone's opinions change on whether this is a valuable thing to have, let me know. I'm still a bit ambivalent (mostly worried that aria-actions with invalid ids will still get exposed, but nothing will show up even after focusing the control)

Why do we want to expose this? We don't normally expose idrefs in object attributes. IAccessibleAction should be sufficient.

As I understand it, UIAccessibilityCustomAction (as linked here) can only be used with Mac Catalyst. Browsers aren't Mac Catalyst apps, so I don't think they can use this. We need the equivalent for the protocol used by Mac desktop apps.

Hi @smhigley: should
|

Consolidating to-dos from the TPAC discussion:
|
Does this mean that the browser must only expose the actions when the object has a11y focus? (via DOM focus or activedescendant). This certainly would make things simpler, because "focusable" is actually not a perfect signal, since we don't know which elements with ids are potentially going to be active descendants. We make good guesses but it's not deterministic. E.g. in Chromium (not sure about others) we expose an element with an id as focusable if it also has a role attribute (not just inherited role from HTML) and an ancestor with the aria-activedescendant attribute present. |
|
@aleventhal either your timing was serendipitous, or you saw my comment here :D Would it make sense to expose only the mapping for object attributes of The use case would be the use cases discussed when a screen reader may want to query either an ancestor of the currently focused element for actions in very specific cases (e.g. in a video player), or want to look at whether actions exist when an element has virtual cursor focus but not keyboard focus. The referencing element would need to be given keyboard focus in order to actually expose the menu of actions, but in theory it might be helpful to know whether an element potentially has actions before giving it focus. I think my worry with that is that it may not be possible in practice to trust that authors who coded e.g. |

Should we have some "User Agents MUST"s here? Aaron and I were thinking something along the lines of "User Agents must not expose aria-actions if the Author MUSTs are not followed".

Oh yeah, I can see why that would be helpful. Do you have suggestions for specific exceptions? The first one that comes to mind is not exposing actions if the element is in focus, but the action ids do not point to an element.
Great questions! I'll go in order:

I suggest has-actions: true
- In the future, the actions could come from HTML
- We don't typically name object attributes using "aria" in the name because at that point as the semantics should be technology-agnostic where possible
- The pattern typically has a value, often "true".
@jcsteh WDYT?

makes sense to me, FWIW. But yeah, I think @jcsteh's sign-off is more important :D
Agree with Sarah here... Example could be that aria-actions points to a single delete button for the collection view while you're selected on any (or multiple) items in the collection.
We discussed this pretty extensively for the author requirement... In order to effectively obfuscate whether the even is being synthesized by AT (Web Design Principle §2.9) the even needs to track as a standard mainstream event, in this case a pointer click. So the author expectation is to make these rendered if not fully visible. We have not discussed UA requirements, other than to obfuscate whether the click is really pointer driven or synthesized. I would not expect a click event to fire on an unrendered element, but I think it's harmless to have the click come in on a rendered-but-invisible element like a button set to Great point that this should be agreed upon language in the spec.
I recall we discussed |
`aria-actions` is a new proposed property that identifies secondary action elements inside a composite interactive widget. An example of this pattern is close button in tabs. This property allows authors to surface the actions directly for discoverability. In the example, when a screen reader user focuses on a tab, they should know that the close button exists. This CL implements the mapping for this property for ATK/AT-SPI using the AtkAction interface. Future CLs will handle - the remaining API mappings - IDL related updates - restrictions on edge cases - has-actions attribute https://chromestatus.com/feature/5161589307867136 w3c/aria#1440 w3c/aria#1805 Change-Id: I8702d279fcf0961c84360d0609b0f2a20d9c049c Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/5925796 Reviewed-by: Alex Rudenko <alexrudenko@chromium.org> Reviewed-by: Dominic Farolino <dom@chromium.org> Commit-Queue: Jocelyn Tran <jocelyntran@google.com> Reviewed-by: Aaron Leventhal <aleventhal@chromium.org> Code-Coverage: findit-for-me@appspot.gserviceaccount.com <findit-for-me@appspot.gserviceaccount.com> Reviewed-by: Scott Haseley <shaseley@chromium.org> Cr-Commit-Position: refs/heads/main@{#1376934}
This new state is set to true if the aria-actions attribute is present and indicates that actions may exist on an element. has-actions is mapped for IA2 and UIA. https://chromestatus.com/feature/5161589307867136 w3c/aria#1440 w3c/aria#1805 Change-Id: I6260d4b047e57b09d078d03822e9bc14bb5fabab Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/5985212 Reviewed-by: Ken Buchanan <kenrb@chromium.org> Commit-Queue: Jocelyn Tran <jocelyntran@google.com> Reviewed-by: Aaron Leventhal <aleventhal@chromium.org> Reviewed-by: David Tseng <dtseng@chromium.org> Cr-Commit-Position: refs/heads/main@{#1379356}

@smhigley Is there some text wrt not including action descendants in the recursive name from contents calculation? |
Actually, a simpler rule to implement would be less general. If the name of the element with aria-actions is computed via name from contents, it should not contain the contents of the target actions. |
Resolves #1440 by adding the
aria-actionsattributeThis has a dependency on the changes in #1454.
