RE: treegrid

Hi Sailesh,

Screen readers do not read row and column headers by default unless the are
configured to do so. It is a verbosity feature. Regardind spans, screen
readers should read rows/column headers the same as the do today for
tables.

The user can always execute a say line in a screen reader. The issue with
tree grids is they may be used for mail applications and there may be a
check box in the beginning. Typically you would want to read entire line
much like they would do in a list box when you traverse the first column of
a treegrid just like for lists in Windows which have headers. ... I will
raise the point with the Freedom Scientific people though. Ultimately, it
is their UI.

Cheers and thank you for the feedback,
Rich

>JAWS will read the entire row when navigating up and down the left most
column. We will not put this in the BPG.
This may be a problem. A user should be able to invoke a key (say line) to
make it speak the row. Maybe I just want to read the values in the first
column only. The behavior should be the same for reading down any column.
The list below did not address how column / row headers  will be announced
as one reads cells by row / column. Also what about support for reading
headers when they occupy 2 rows or use colspan type of design?
Thanks,
