Hi, Sam
* SPI_STATE_ACTIVE: Indicates a window is currently the active window
Is this what you want?

Steve, thanks for your reply.

I called gtk_init(null, null) and then tried using
gdk_display_get_window_at_pointer() and gdk_window_at_pointer(),
both returned null, which I'm interpretting as "that window
belongs to a different application -- you do not have access".

I decided to drop down to XWindows.  I have been able to find the
XWindow under the mouse and match its geometry (x, y, width, height)
with the Accessible *window obtained from ap-spi, so this might work.
Of course if there happened to be multiple identical windows at the
same spot, I would not be able to distinguish them.

This brings up two questions:

1. Is there a way to map from an at-spi Accessible *value to its
   associated XWindow window?
2. Is there a better alternative than XWindows for doing this?

Thanks.

-Sam

Sam, this is something where you may need to look outside the a11y API.
e.g the windows manager

Happy new year

Hi Sam (and hi Steve)

You might find libwnck useful:

http://library.gnome.org/devel/libwnck/stable/WnckWindow.html#wnck-window-is-above
(and wnck_window_is_below)

Note you could use libwnck API... or find out how it is implemented
under the hood :)

cheers,
David

Thanks David. I knew there was a library we used in Python for
accessing WM features that had a strange name. Yep, that's the one.

I precisely asked for an API to get this information some time ago, but
it was rejected because it was said that AT-SPI engines shouldn't assume
that the desktop is an X-Window desktop.  So there is currently no way
except the kind of tinkering you have figured out.

Samuel,

= it was rejected because it was said that AT-SPI engines shouldn't assume that the desktop is an X-Window desktop.

I'm ok with the rejection as long as I can use AT-SPI for everything.  But now that I have to use the underlying window manager to figure out which window is on top, I'm with you: it would be nice to be able to map AT-SPI windows to window manager windows, whether it's X or WIN32 or whatever.
