RE: Question about ARIA 1.1 haspopup attribute

Thanks Stefan.

 

I look forward to your testing assistance, especially if you will help raise
bugs with browser and assistive tech developers. I have observed multiple
instances of need for both. Good quality bug reports with accurate and
reliable reproduction procedures will take some time.

 

Matt

Matt, Bryan,

 

You guys are doing a super job to back up the APG with all the examples
planned .

I understand the situation and I agree that elaborated examples are the
first step for cross-AT compliance.

I believe one these examples have been carefully scrutinized be AT, braowser
and control developers many of the existing issues can be addressed.

 

As I did in the past I do offer some testing services for the combinations
FF/IE + JAWS/NVDA as soon as the new example suite is completely online.

I am always open for discussions about this and can give input what is
needed from a business perspective, too. 

 

Let's hope with the increased number of AT developers involved we can get an
even better overall WAI-ARIA coverage in 2017!

 

Best Regards

Stefan

Stefan, that is a good choice of words, "expected". I would say that we have
assistive technology expectations of some kind for all attributes, including
haspopup, but there is no such thing as an ARIA compliant assistive
technology. That, as you know, is a long-standing working group decision
about the scope of the ARIA specification. Of course, it is a decision that
was made and revisited at specific points in time and made for very
practical reasons that considered the landscape at those times. Whether or
not there has been sufficient change in the landscape to justify
reconsideration is a very good question.

Yesk, very, very well.

 

This is one reason Rich has been working hard to get more participation from
assistive technology developers. But, it is very difficult for them to
balance effective participation in web standards and requirements with the
rest of their business.

 

We believe we will have more AT developer participation in 2017.

Yes, unacceptable in the long run.

 

BTW, normative requirements for AT are not the only feasible approach to
changing this reality. To start with, we have not even had authoritative
reference implementations of ARIA that can be used by assistive technology
developers. That is a huge, I believe primary, reason for the massive
inconsistency. And, that is why I am so heavily invested in filling the gap
with the authoring practices guide.

Matt, Bryan,

 

Many thanks for fast reply. I'd like to ask one more thing:

 

>>> there are no requirements for assistive technologies to render
information about aria-haspopup

 

Does this mean we have a two-class society regarding ARIA attributes, such
like aria-checked where it is "expected" that AT renders info and such like
aria-haspopup where this is in the mercy of AT to render info? I mean we
should develop a common understanding here what is a "must" and what is a
"may".

Not only on the API level (as it happens in the ARIA core specs) but also
for AT. An overview table with musts and mays would help here.

 

I understand that you cannot force AT people to support things but on
consultation level I feel a bit fooled telling a developer supplying a
property just MAY work - know what I mean? This has also implications for QA
processes, what should I tell an accessibility tester? "Oh yes we are
supplying property x but AT just ignores it or interprets it differently" -
my everyday reality but unacceptable in the long run.

 

Regards

Stefan

Stefan,

 

I agree that such a use of aria-haspopup is consistent with the spec. 

 

However, given there are no requirements for assistive technologies to
render information about aria-haspopup, discoverability can be an issue. So,
I would avoid using such menus as the sole path to critical function in a
self-service application. Although, for most applications, this
discoverability issue likely affects experience design for audiences other
than just assistive technology users. 

 

Given you address discoverability, I think context menus are often an
awesome way to provide enhanced productivity for everyone, and signaling
their availability with aria-haspopup is good practice.

 

Matt

Hi,

Yes, aria-haspopup is still needed in this case, and I recommend 'true' at
this point since this is the only supported value at present in ATs.

 

Examples of different types of controls that use this model can be seen by
expanding the "ARIA Menus" button at

http://whatsock.com/tsg/#tgl-2-5

(Simply scroll down to the Variations links to the live demos, which include
simulated and native controls like form fields as well.)

 

These live examples too can be downloaded directly in the archive at

All the best,

Bryan

Subject: Question about ARIA 1.1 haspopup attribue

 

Hi Matt, Bryan,

 

a discussion came up here how to signal to blind users that a control with
an ARIA role has a custom (non-standard) context menu (a menu representing
all functionality associated with a control, not a list with values).

 

I am not talking about menu buttons here where the aria-haspopup pattern is
an integral part of the concept. I am talking about checkboxes, links etc.

 

Is ARIA 1.1 aria-haspopup="menu" here nevertheless aproppriate?  If not, is
there annother mechanism using ARIA to indicate custom *context* menus?

 

Or isn't that needed since we once discussed that form elements doesn't need
extra haspopup indication since they always have a (default) browser context
menu associated? I mean there is a design principle "Don't report normalcy"
and this I consider this relevant to be pointed out.

 

Best Regards + have a great christmas!

Stefan
