Hi Pete,
Returning the line number seems very odd to me; I would avoid it.
Here's why:
- Some documents/apps do line numbering for the entire document
- Some documents/apps do line numbering per page
- Most documents/apps don't have this
- In many situations, resizing the text field will change the line
breaks (and thus the numbering)
- Some documents/apps only present the portion of text showing in
the window (e.g. OpenOffice Writer)
Also, it should be pretty straightforward to count the number of line
via our existing API.
Regards,
Peter

Apparently Firefox returns a "line-number" field in the object
attributes for a text control. I found the FF IA2 spec at
https://developer.mozilla.org/en/Accessibility/AT-APIs/IA2/Attrs
which just points you to the Gecko spec at
https://developer.mozilla.org/en/Accessibility/AT-APIs/Gecko/Attrs
The IA2 object spec, which is a work in progress, is at
http://www.linuxfoundation.org/en/Accessibility/IAccessible2/ObjectAttributes
What are your thoughts on adding line-number to the spec?
By the way, the IA2 object attribute spec was started when Symphony was
done but FF
IA2 support was still not complete. So a larger question is if we
should harmonize the current IA2 and FF object attribute specs,
hopefully borrowing from other mature specs like CSS2 (or maybe even
CSS3). Or should we eliminate the IA2 object attribute spec and
instead have each app document its own object attributes. The former
would be better but perhaps not practical. I'd like to know what the
list thinks.
Thanks, Pete
