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

Howdy Joanie,

for the key event issue:
i just picked up this again. i remembered that Kate has the same issue  
by interrupting. Frederik wired up some experimental code what should  
fix it in Kate. Maybe it improves the situation here too:
https://codereview.qt-project.org/#/c/245319/
its still in review currently.

as for the filler role, i understand. sounds like something i would be  
able to change. if it is a "icon" i stay in same trouble as i added  
the desktop icons accessibility. QT seems not to offer a "Icon" role.
https://doc.qt.io/qt-5/qaccessible.html#Role-enum
for the destkop icons i used "canvas" but its also not the best  
solution i think. maybe this needs to get added in QT? Or maybe  
QAccessible::listItem? the docu says also
QAccessible::Graphic "A graphic or picture, e.g. an icon."
what sounds wrong somehow? not sure whats the best. but whatever we  
use, i will sync it up with the desktop icons, as it currently says  
"Icon Name Canvas" (german lainwand) whats not so elegant as well.

cheers chrys
