Hello Christophe and all.
There are several kind of accessibility issues all around the suite. In
example, it is not possible to read a document from the beginning to the
end using the appropriate Voice Over command: the TTS stops reading
paragraph. There is no way to know for sure if a page is complete and a
new one is beginning. Only basic text attributes are reported by the
reader: in example, I can find out if a text is bolded or underlined,
i have no way to figure out if it is superscripted or not. If an image
present, Voice Over doesn't report it. I can create a table, but I
explore it or even know that a table is present.
Can you do all these things in iWork Pages or other office suites that are
available for Mac OS (NeoOffice, IBM Lotus Symphony)? If yes, then we
should look at registering bugs for LibreOffice. The bugs have probably to
do with missing or incorrect mappings between the internal OpenOffice.org
API and the native (accessibility) API for Mac OS. I don't know enough
about the Apple APIs to suggest specific improvements. I only know that
text features like bold, italic and underline are not part of the NS
Format/character or format/paragraph are dialogs witch a VO user can
understand with no little difficulties. From a... blind point of view,
the options are grouped by category.
"Format Paragraph" and "Format Character" are dialogs with tabbed
interfaces. When you say "category" are you referring to the different tabs
in these dialogs or to groupings of controls inside the tabs?
(All accessibility APIs that I am aware of, except those on Mac OS, have a
"role" for "tab page" or "tab item". I don't know how tabs are identified
to assistive technology on Mac OS.)
There are several buttons to select
the options category you want to change or review. Ok, with Voice Over I
can access them, but the options and their parameters... that is a
completely different story! I cannot use standard VO movement commands,
have to use the tab key instead. But, if I do so, Voice Over do not
announce the controls' labels. And, even if I can change values in edit
boxes and check and uncheck check boxes, there are other controls I
access with the keyboard, in particular pop up buttons.
This could be due to missing mappings to the Mac OS accessibility API,
especially if you encounter no such problems in other applications. This
can probably be checked with the Accessibility Inspector: see
Can anyone with access to a Mac system do this and report back if labels
are actually connected with the corresponding controls?
Some dialogs are a
little bit confusing: when I explore them using VO standard movement
commands, the controls are reported in a meaningless order: in example,
and Cancel buttons should be the last two controls within a dialogs; in
some cases, they are not.
I think these issues need to be registered as bugs. I would suggest one
bug per dialog, and each bug should precisely describe in which order the
controls are encountered. Do you know how and where to report bugs?
All that I am talking about is referred to Writer. Of course, there are
similar list of issues for Calc and, if you want, we can discuss it.
If you want to discussed the issues in other applications, I suggest that
you create a separate discussion thread for each application, just to make
it easier to sort through e-mails ;-)
Last but not list, I apologize for my horrible english. I do my
and hope you'll understand.
Don't worry. I think we understand each other.
