Re: [orca-list] Qt 5 accessibility

I'm stating the obvious, so please forgive me/not meaning to insult anyone's inteligence. 
For most of us the screenrader taht most interests us is Orca. While all screenreaders have their quirks, 
strengths and 
weaknesses and should be tested thoroughly in an ideal world, orca is probably most likely to react 
differently to others 
I think so should receive priority in testing, probably along with NVDA when time does not permit testing on 
all popular 
screenreading programs. 
Thanks again for your interest in this.

Hi Peter and all,

Hello,
I am sorry my attempt at some kind of report was not something you would
consider as a polite request. Anyway is there a way for you or someone
else close enough on the team to at least do some verry basic testing
with the real screen reader orca on linux in this specific case please?


I do this regularly and one issue just came up which was completely unexpected 
to me. I run KDE usually and thus get one of the Qt default styles. But of 
course most Orca users use Gnome and Qt tries to adapt and be visually 
pleasing and thus loads the GTK style which integrates nicely but fares much 
worse when it comes to a11y. I haven't thought about this being an issue 
before and I guess we were experiencing completely different behavior.

As a quick test, can you run the application on the command line with "-
style=fusion" as parameter? For me that makes a huge difference, as in Orca 
barely working and working nicely.

I'm currently on the road, so I'll not get around to looking at this properly 
for the next few days.
https://bugreports.qt-project.org/browse/QTBUG-39419


Also would you like me to write reports in a way so you will get steps
to reproduce, current behaviour and expected behaviour? This is
something I believe I can do and if it may eventually help to make QT
accessibility become even better in the future, then I am happy to do that.


That would be really great. Usually the issues are pretty obvious (even though 
you'll have to bear with me, I'm still learning all the time), so a short 
description of what doesn't work and how it should be is indeed the right 
thing. Please be sure to use GUI: Accessibility as Component, then it ends up 
being assigned directly to me and I'll deal with it.


I haven't tested QT5 on windows so I can't comment on this right now but
I can remember having issues for example with tabcontrols on all the
platforms in the past so I've assumed most of these critical issues
target multiplatforms where possible.


We radically reworked many parts and moved away from some of the old MSAA 
APIs, of course it depends on the screen reader used, but I usually check at 
least with NVDA and it seems to me that Tabs work. Please let me know if they 
don't. As said, I usually check that screen readers read the items (such as 
each tab name) and that it works with keyboard. I may very well get details 
wrong and sometimes Qt behaves slightly different from GTK.

Greetings,
Frederik



Thanks and greetings

Hi,

Peter, thanks for your feedback. In the last three months we closed 44
accessibility issues in Qt, of course not all of them will end up in a
release right away. Also I personally worked on a lot of Mac and Windows
issues since I got high quality bug reports on these platforms.

This is the first time I get any feedback when it comes to accessibility
on
Linux with Qt 5.3, so I am not surprised that there are issues. Please let
me know when you run into problems.

Hello,
I have briefly tested transmission-qt with QT 5.3 on arch linux today.
I am not happy to report that:
- comboboxes


I wonder if the problem you are seeing is this bug:
https://bugreports.qt-project.org/browse/QTBUG-36814
(fixed in 5.3.1)


, sliders appear to be still broken ei.e. not correctly
firing value change events.


Can you please give more details? I just tested a simple Qt example that
ships with Qt (widgets/sliders) and for me sliders work (Orca announces
the new value after pressing the arrow keys.
Funny enough sliders and dial don't do that.
https://bugreports.qt-project.org/browse/QTBUG-39394


I am having issues navigating in edit fields (note this appears to be
working better with QT4).


Please give more details. Ideally a bug report at
https://bugreports.qt-project.org (the account creation currently has a
visual only captcha, sorry for that. Upgrading the bug tracker is
scheduled but non-trivial, but you can send a mail to
jira-admin qt-project org and will get an account).


Perhaps there are under the hoodstability and other fixes but I am
afraid real accessibility testing by the potential users is either not
taken into considerations while working on this or it's being put aside
for the consideration to the future updates.


We test as much as we can, but not depending on a screen reader it's
sometimes hard to tell what is working and what isn't. So please give
feedback, otherwise I cannot spend time on this.

Greetings,
Frederik


Other things which I can't say are QT5 issues or might be app specific
issues is that flat review does not work and some of the controls don't
convey its role and state.
I have studied no implementation details I have observed all this by
running orca and my guess work as I can't see at all.

I am looking forward to some real exciting developments on this front.

Greetings

Hello,

since Qt accessibility comes up as a topic every once in a while, I
thought
I'd give a short update.

Qt 5 is looking better and better when it comes to accessibility. Today
Qt
5.3.0 was released and the release contains quite some improvements
across
the board and on all platforms. I recently wrote a blog post about it:
http://blog.qt.digia.com/blog/2014/05/14/accessibility-in-qt-5-3/

Since KDE is slowly moving towards a release based on Qt 5, I hope that
we'll be able to provide a decent experience for everyone from the
release of Plasma Next and onwards. By the way, the old environment
variable to enable accessibility has been retired and Qt now ships and
builds all accessibility code by default, not depending on external
plugins any more.

I'd also like to mention that we now have a dedicated mailing list to
discuss Qt accessibility issues:
http://lists.qt-project.org/mailman/listinfo/accessibility

Another nice project that just started is a cooperation to improve
accessibility for Qt apps on mobile devices (targeting Android and iOS).

Let me quote Trenton:

My name is Trenton Schulz. I’m a senior research scientist at the
Norwegian
Computing Center (Norsk Regnesentral), and I’m working with Digia on
our
BestApps project [1] for increasing the accessibility of mobile apps.

Currently, we are doing some user investigation about how different
people
use assistive technology (AT) with their smartphones and apps. In
connection with this, I would be interested in finding people that
would
be
interested in participating in a small interview (either over
telephone,
Skype, or email) about how they use this technology. We are holding a
workshop connected to this as well on 19 June in Oslo.

So, if you are interested (or know anyone), please let me know via
email
and I can send more details. Your input can help make future Qt
applications more accessible and easier to use for everyone.


I'm looking forward to feedback from the Orca users as more Qt 5
applications become available on Linux.

Greetings,
Frederik

PS: Qt 4 is in maintenance mode and there will be no real changes in
accessibility for it.
