Re: [orca-list] If you are using Mate with Braille please contact me.

    Hello Tom,
    
    Which Mate version are you using? Are you sure do you have the
    default Mate? I know Ubuntu Mate does a lot of customization on Mate
    
    
    Best regards.

My desktop has plenty of files and orca does not respond to any keys so I would surmise that nothing has focus.  I know alt-tab does nothing in my case at least as far as orca is concerned.

+ Orca-list for MATE folks.

Hey Tom.

Thanks! Here's the relevant part of your debug.out (with timestamps and "INFO:" trimmed for readability and extra space added to group the checks together):

Looking at [window | ] from [application | marco] marco

[window | ] is not active and showing, or is iconified

Looking at [frame | Top Panel] from [application | mate-panel] mate-panel
[frame | Top Panel] lacks state active

Looking at [frame | Desktop] from [application | caja] /usr/bin/caja
[frame | Desktop] lacks state active
[frame | Desktop] is not active and showing, or is iconified

Unable to find active window from [list of all applications, even those which don't have any windows, e.g. Orca, mate-settings-daemon, etc.]

So... The question is what -- if anything -- are you in or has focus? My guess is that it's safe to eliminate the top and bottom panels. And if memory serves me the window from Marco is what you wind up in when you use Alt+Tab. So you're not in that. The only candidate is the Desktop.

You can do a functional test to see if the Desktop is active by putting some files in $HOME/Desktop. Then, when you start up and Orca just says "Screen reader on," press navigation keys which should work on the Desktop like Home, End, Left, Right, Up, Down. If one of those keys causes the selected/focused item to change, then that's where focus is. In which case, the MATE folks should see about adding the "active" state to accessible state set of the Desktop frame. Then Orca should tell you you're on the Desktop and if it finds a focused icon, present that as well.

On the other hand, if pressing those keys doesn't work without your having first explicitly given focus to the Desktop, then I suspect that when you start up your session, absolutely nothing has focus and you are not physically in any window. Thus Orca has nothing to present as the active window or focused item. If this is indeed the case, perhaps the MATE folks could consider putting focus *somewhere*, like the Desktop, for all users.

Related aside: Orca used to say "no focus" to indicate that condition, but doing so reliably was problematic: There are often very brief moments where one is in limbo between a window becoming inactive and a window becoming active. If Orca doesn't wait a sufficiently long enough time, Orca would be regularly spamming you with "no focus" messages. On the flip side, if Orca waits too long to tell you nothing has focus, you've probably already reached this conclusion due to the silence and caused something to gain focus rendering the eventual "no focus" message pointless. I had tried to strike a balance in between these two extremes, but "no focus" messages still crept through on occasion and users complained. So the "no focus" message got removed.

I'm dealing with some Chromium issues at the moment, but I'm hoping the MATE users -- and in some cases MATE contributors, like Hypra -- will read the above and either fix the missing state (if the Desktop really is active) or see about causing the Desktop to gain focus or clue me in to something I'm not aware of. :)

Thanks!!

Hi Joanie

Here is a debug with orca starting.  Not a high priority as I can easily work around it but might be interesting to know why orca says nothing but "screenreader on" until I go to the menu.

Hey Tom.

When Orca is first started, it tries to find the active application window. If it finds it, it should present it. Also if it finds it, it then searches for the focused object in that window. So my guess is that Orca is not finding an active window. If you care as to why, capturing a full debug.out would be helpful. I'm happy to take a look.

If the scenario is that Orca is being started automatically along with the desktop, the approach of relaunching Orca and cycling through levels presumably won't work. But on https://wiki.gnome.org/Projects/Orca/Debugging, under item 2, you'll find something which should work, namely using orca-customizations.py to set up the file and debug level
ahead of time.

HTH.
