RE: treegrid

Richard,

 

Sure I know reading column / row headers is a verbosity setting. I was
asking whether  they can be programmatically determined. 

Setting the reading algorithm based on one use-case (first colum=checkbox)
is perhaps not the best way to proceed. 

In that case, the checkbox should be programmatically labeled by the cell
containing the key value for the row. The user should not be expected to
listen to a string of cells and determine which is the row identifier.

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

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,
