RE: calculator clarification

["Ravinandan Arakali" <ravinandan arakali wipro com>]

Hi Bill,
Thanks for the info. Yes, what you said about the digits 0-9 makes sense.
When I proposed tooltips for 0-9, I was imagining AT applications which
might look at only the description(tool tip) attached to a button to
describe
it to a disabled user.
Are there any such AT applications ?

Regards,
Ravinandan

Hi Ravinandan:

I expect that tooltips on 0-9 would add little of use from an
accessibility point of view, since the labels are already exported via
the default implementation of atk_object_get_name () for buttons.  The
'e' button probably could benefit from a tooltip, if only something like
"e (base of natural logarithm)".

[Padraig: correct nomenclature? ;-)]

The tooltips are exposed via accessibility interfaces as
atk_object_get_description ().  If the tooltip were not necessary for
normal use the same end result (from an accessibility standpoint) could
be accomplished by explicitly setting the accessible name/description of
such buttons inside the calculator code:

   atkobject = gtk_widget_get_accessible (e_button);
   atk_object_set_accessible_name (atkobject, "base e");
   atk_object_set_accessible_description (atkobject, "base of natural
logarithms");

My opinion is that just setting the tooltip for 'e' and other non-digit
buttons will be sufficient.

Best regards,

-Bill
