Orca Structural Navigation for Links has been added

Hi All.

I have just checked in a change to Gecko.py which adds
support for 
structural navigation by link in Firefox.  U is for the next
unvisited 
link; Shift+U for the previous unvisited link; V for the
next visited 
Link; and Shift V for the (yup, you guessed it) previous
visited link. 
<smile>

Take care.
Joanie

Hi Joanie,
thanks for that quick accomplishment of the FF functions.
However: I've to put some water into the wine, because the
"v" and
"shift+v" keys don't work at all.
I've tested it on several homepages:
http://www.dradio.de
http://ww
w.f-r.de/rss/nachrichten/index.xml
If you open any link, return to the former page and try to
search for a
visited link, you always hear: "No visited link".
I use the very latest FF3.
Maybe a problem of the HTML code. I guess you've tested it
on several
sites, which ones?
Regards
Hermann

Hi Hermann:

I just tested this with Orca 2180 and FF3 (Gecko/20070313 
Minefield/3.0a3pre) using the specific pages you list below.
 The v, u, 
shift+v, and shift+u commands seem to work well for me. 
I'll download 
the latest Firefox to see if it behaves any differently.

Hi Joanie,
the mail was rejected again, so I repeat it in cas you
missed my 
answer:
I retested the page, and it definitely doesn't work.

Hi Hermann.

If you could send me a full debug.out that would be awesome.
 Yeah, I 
know, if Comcast wasn't blocking your ISP.... (I don't use
their spam 
filtering, so it's some system-wide thing.  But I'll call
them.) Options 
in the meantime:

1. Attach it to bug 417001 on bugzilla (that's the original
RFE)
2. Send it to the list (without putting my name in the To or
CC fields)
3. Send it to my work address:  joanmarie.diggscarroll.org

The first two are preferred because I generally only check
my work mail, 
well, when working on my "real job".
<smile>

Thanks in advance!!
Joanie

Hello Joanie,
as an attachment I send the debug.out.
I only tested the dradio page, but I think that's
sufficient.

Hi Hermann.

Okay, I *believe* that I followed your steps exactly.  Just
to be sure 
we're on the same page so to speak, here's what I think you
did:

Loaded the page, tabbed to the first Vorschau link (the one
immediately 
after Wir über uns), and pressed Enter to follow that link. 
On the new 
page, tabbed, shift tabbed once, and then tabbed until you
got to the 
Sitemap link, at which point you pressed Alt Left Arrow to
return to the 
previous page.  Focus at that point was on a link called
"Vorschau," and 
I'm guessing from what the contents of the braille display
indicate, 
that it's the same one that you followed.  Then you tabbed
once to the 
Frequenzen link and pressed V.

Operating under the assumption that I captured your steps
correctly, I 
cleared my history and followed them.  And, sure enough, I
got the same 
results you did.  But when I pressed Shift V, I was returned
to the 
first "Vorschau" link.  If you have not followed
other links on that 
page, I think what is happening is that you are tabbing past
the one 
visited link in which case there are no more visited links
moving 
forward; only moving backward.

Does this make any sense?

Take care.
Joanie (who called Comcast and was told that there was
nothing they 
could do <grumble, grumble, grumble>)

Hi Hermann, all.

Hermann and I started an off-list conversation surrounding
my Comcast
issues and switching to Gmail.  But Hermann's question is
one that
should be on-list I think (hope you don't mind Hermann!):

> How does Gecko.py identify visited links? Could it be a
colour problem?
> I think visited links are shown in a different colour,
right?

Visited links are sometimes shown in a different color;
sometimes not.
In the old days they always were.  Then folks figured out
ways to make
their pages prettier by controlling link colors. 
<smile> 

Regardless, it is not a color problem because we're not
looking at the
color when determining whether or not a link is visited. 
One of the
properties of links exposed via at-spi is its visited state.
 The script
looks at the next (or previous) link and through at-spi says
"hey, have
you been visited?"  If the link claims that it has, we
stop; else we
move on to the next (or previous) link.  So, potentially the
problem is
that a link is lying about whether or not it's been visited.
 But I
don't think that's the case....

Is there any chance that in your Preferences dialog, under
Privacy, you
unchecked the checkbox called "Remember visited pages
for the last X
days?"  If you uncheck that checkbox, Firefox won't
remember visited
pages and links that you visited will no longer claim to be
visited.

If that isn't it.... Would you mind doing the following:

1. Go to dradio.de
2. Follow a link, then immediately press Alt Left Arrow to
go back
3. Tab a few times, follow another link, then immediately
press Alt Left
Arrow to go back (do this a couple of times)
4. Then try V and Shift V

Thanks!
Joanie

Yeah! That privacy settings do the job.
I use to treat such settings restricted, since I don't want
to keep so
many sites in my browser's cache. Maybe a bit German
<smile>, but
privacy is a top issue in our country.

Awesome!

I won't comment about privacy issues in the U.S. other than
to say I'm a
card-carrying, dues-paying member of the EFF. <grin> 
As for that
setting: You could lower the number of days to, say, 1. 
Seems 9 is the
default.

Thanks for all the testing and feedback!
Joanie
