Hello,
A quote from the blog...
When an application sets a “default” action, the cursor changes to a
pointing hand to indicate that the popup itself is clickable.
This needs to be modified if the author wishes to improve the
accessibility support.
I think we are missing robust and very accessible access to notifications.
GNOME's notifications can receive system focus, it can be controlled
from the keyboard to an extend but it is not possible to execute actions
associated to notifications.
Orca it-self has some notification-daemon built-in support that indexes
notifications as soon as they are issued, however again orca can present
these and the presentation is perfectly accessible however it's not
possible to directly act on the notifications this way.
Another thing might be configurable is that orca indexes the
notifications until it's restarted and does not dismiss these when the
notification is acted on in another way. For example if I receive a new
message in thunderbird, I switch focus into the thunderbird window, read
the unread message and notification is removed from the notification
area. Orca will still present it in its notification list.
Ideally we'd need to make some notification pannel accessible the way
you Chrys are trying to do now.
However I am not sure we can find enough support upstream and perhaps
developing accessible client for notification daemon is something that
should be considered.
I am not very experienced in this regard but ability to bridge
notification importance to speech-dispatcher priorities, ability to act
on the notifications, ability to hide certain notifications, ability to
group notifications by an app or device that has issued them, ability to
assign sounds
would be cool features for a modern desktop.
I am not sure some of these features are currently possible right now
but I think that would boost productivity forward for visually disabled
users too.
I know such a view may only have emerged recently after we became
spoiled by notification handling on mobile oses.
But remember those who don't need accessibility support may eventually
get linux on their mobile devices in the foreseable future. We are kind
of jealous and we'd prefer that too if it would be possible of course.
Greetings
Peter

Howdy Joanie,
oh this is pritty awsome! thanks for this information.
I will forward it to plasma-devel and kbroulik. fore sure they will
like your answer!
mercy,
cheers chrys
Zitat von Joanmarie Diggs <jdiggs igalia com>:
Hey Chrys.
Regarding notifications, it should be pretty simple:
1. Give it ROLE_NOTIFICATION
2. Be sure it emits an object:state-changed:showing event
3. Be sure the displayed text is exposed via the accessible text
interface, either on the notification itself or in the accessible
children of the notification
In theory, that should do it. Orca's looking for notifications that
announce their appearance because, like you stated, they don't get
focus.
Hope this helps. BTW, I'm not subscribed to plasma-devel, so I'm not
sure if my CCing them will be sufficient. If it's not, and if they need
what I've stated above, please forward it to them.
Thanks again for all your work on this!

Howdy Joanie,
I just give an talk to kbroulik ( the creator of Plasmas new awsome
notification system).
see here:
https://blog.broulik.de/2019/05/next-generation-plasma-notifications/
He told me that accessibility is not yet implemented. But I see
notifications are an very importaint part of an desktop system. Problem
for make it accessible is, that it currently doesnt get the focus at
any
time.
Is there a best practice to implement this?
how does gnome do this? how is orca awaiting for incomming
notifications? do you know how we can make this happen?
Sorry for bother you with so basic stuff but you are the only one
person
I know what can answer those issues properly.
maybe a nice side notice for you (and others). We currently work on an
accessibility HIG for KDE.
https://hig.kde.org/accessibility/index.html
Still a WIP, but if someone wants to add some good content just
contact me.
It should contain:
- Keyboard navigation
- Focus handling
- Set A11y Lables/ Descriptions/ roles
- howto test for good a11y
cheers chrys
