Description Alex ARNAUD 2017-10-05 13:39:43 UTC 
Description:
Dear all,

LibreOffice find search entry has a broken accessibility tree when it emits events so Orca screenreader cannot determine it's a LibreOffice event and doesn't present it to the user.
When the user write text in the find search entry and it want to read the text LibreOffice should emits caret-moved events, it the behavior we do since the fix of the bug #99687. Unfortunatly when the event is emitted the parent of the emitter is -1 so Orca can't present the information to the user. See the AT-SPI related documentation: https://lazka.github.io/pgi-docs/Atspi-2.0/classes/Accessible.html#Atspi.Accessible.get_index_in_parent

Steps to Reproduce:
1) Launch the attached event listener
2) Launch LibreOffice Writer
4) Press ctrl+f and type "test"
5) Press left or right arrow

Actual Results:  
LibreOffice sends the events and when the listener ask for the parent index it obtains "-1"

Expected Results:
LibreOffice should send the event and correctly set the parent index


Reproducible: Always

User Profile Reset: No

Additional Info:
Best regards.

I can reproduce with an old version from the bibisect repo:

Version: 6.0.6.0.0+
Build ID: c6c82096301180cfa7942dd9fb9d1cb66c7ecc04
CPU threads: 4; OS: Linux 5.16; UI render: default; VCL: gtk3; 
Locale: en-GB (en_GB.UTF-8); Calc: group

but everything looks fine with current git master, Orca speaks the corresponding character and the attached script prints 0 as index in parent, no more -1:

> object:text-caret-moved(1, 0, 0)
>         source: [text | ]
>         host_application: [application | soffice]
>         sender: [application | soffice]
> 0
> object:text-caret-moved(2, 0, 0)
