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

[Joanmarie Diggs <jdiggs igalia com>]

OK, that got things working. Thanks! Mind you, by working I mean it
eventually shows up in Accerciser and Orca. I am seeing delayed
responses, including in Accerciser, and a lot of console spew in the
terminal where I launched Dolphin, including lines like:

qt.accessibility.core: Cannot create accessible child interface for
object:  PlacesView(0x5597ab8ce650)  index:  12

QSpiApplication::keyEventError  "org.freedesktop.DBus.Error.NoReply"
"Did not receive a reply. Possible causes include: the remote
application did not send a reply, the message bus security policy
blocked the reply, the reply timeout expired, or the network connection
was broken."

Anyhoo, I can see state expandable and confirm Orca is not presenting
it. I still need to debug why.

Thanks again!
