Re: [orca-list] KDE Plasma 5.15 Task switcher

[Joanmarie Diggs <jdiggs igalia com>]

Hey again.

I just created an initial script for kwin based on the new switcher
script I created. It improves the situation regarding interrupting
presentation.

That said: One of the things which causes Orca to interrupt presentation
is keyboard events. We aren't seeing them from kwin. In other words,
when you're in kwin, Orca has no clue that you have pressed any keys. At
least not in my environment (which admittedly is Fedora 29 in which I
installed Plasma packages and dependencies from Fedora 30 which isn't
shipping yet). I believe that if we start getting input events from
kwin, presentation by Orca would be further improved.

Beyond that, "filler" is a rather unfortunate role for the thing in the
switcher emitting focus-change events. Right now, Orca is looking for
that role in its heuristic for identifying events from the switcher
container for kwin. Any chance we could get another, better role for it?
If so, I'll immediately update the heuristic. :)

If you look at
https://developer.gnome.org/atk/unstable/AtkObject.html#AtkRole, you'll
see the definition of ATK_ROLE_FILLER is "A object that fills up space
in a user interface". And while the thing on the screen getting
highlighted is arguably an object filling up space in a user interface,
I believe that the closest equivalent in Gtk+ is GtkAlignment ("A widget
which controls the alignment and size of its child"). Fillers are
normally things to be ignored by Orca. To me, the selected thing in kwin
looks more like an icon. And there is an ATK_ROLE_ICON.... I'd entertain
other proposals as well. :)

Please let me know what you, Frederik, and other members of the KDE
community think about the role change. And also please let me know if
what's in Orca master does indeed make things better with respect to
kwin presentation.

Thanks!
