Re: [orca-list] a couple of weird issues with orca's flat review, and changing labels

Hi,
I can confirm this but I noticed this when using Byobu and reading status lines near the bottom of a terminal.

Nautilus, pcman fm or any other file manager of your choice will report current progress by increasing value on a progress indicator. This can either be seen when progress announcements kick in or with flat review. The copying dialog will also contain approximate estimated time displayed on a label. By using the flat review we can see progressbar is updating. Label is also updating but orca is not seeing updated content and in order to update switch to other windows and then switch back is required.

hi all
I've noticed a couple of strange issues with the latest version of
orca, v3.14. These mostly happen in mate, since that's my every day
desktop but they might be desktop agnostic. The first is this. When in
an application where the on screen text frequently changes, an
update-manager would be the best example I can think of, if you use
flat review to review by  word or line, orca will only report the
lines it could see when you entered flat review. For example, if you
check on the status of updates, and orca saw updating linux, but the
text has since changed to your system is up to date, orca would still
report updating linux. This isn't limited to text, either. If there
are any progress bars, orca will report the progress bar in the state
it was when you entered flat review. Of course orca will still anounce
the new progress bar updates, but it can't see them with flat review.
What's interesting, is if you flat review by character, this doesn't
happen. Orca can track the changes in labels and text, and report
them, it just can't with larger units of text. I haven't a clue what
might cause this. I seem to remember people writing in saying they
were having issues with orca reporting old text, and this might be the
cause. This happens anywhere labels can change. On panel applets,
battery charge monitors are particularly vulnerable to this, and in
volume applets. I'm almost sure this is limited to mate, or at the
very least, gtk, because I recently tried trisquel, and it seems to
have indicators, which don't suffer from this. I'm stumped. Could this
be an orca issue? At-spi? Something with mate not re-drawing the
applets? I don't think it's the latter, because if I go into an
applet, such as a battery applet, the percentage gets reported
correctly, it's only the label on the panel that isn't correctly said
by orca. A restart of orca fixes most if not all of this, and
sometimes, such as progress bars and dialogs, a tab away from and back
to will fix it most of the time. Can anyone else confirm this? This is
*not a complaint at all, just a little confusing.
Thanks
