[orca-list] collapse/ expanded /expandable state of tree views in QT4/ QT5 applications

[chrys <chrys linux-a11y org>]

Hello Joanie,


i currently work on some KDE accessibility. i recognize that orca does 
not speak the collapse/ expanded /expandable information for tree views. 
I checked with Accerciser, it looks like the information is available. 
could you add them to the presentation? that would be very cool :). thanks!

reproduce:

install "dolphin" the file manager of KDE

open dolphin -> select the tree view

arrow around up/ down and expand/ collapse items with arrow left / right.

result:

dolphin is perfectly accessible but the collapse/ expand information is 
missing.


other example would be the room list of "mumble". an popular VIOP chat 
application.


cheers chrys
