More or less.  But a notification in the sense of libnotify is
transient; what I'm working on is the state of an application, which may
change over time (controlled by keyboard events, already handled in a
non-toolkit application) ; the whole state is currently a single text
label.  I'm not sure if I have to worry about focus, as only one element
is present.  The graphical interface is even fullscreen, so there's
absolutely nothing else to be presented.

Thanks; this matches what I read.  Indeed my code has to work as a server.

I'll keep that into account.

I had seen no code doing it.  Thanks.  That might be the solution of all
my problems.

Your answer seems very useful, but I don't see any misconception I had
with respect to servers and clients.  Have I missed something?  I really
would like to understand this better.

Therefore for clients.

AT-SPI clients seem very easy to write; I've played with the C programs
in https://github.com/infapi00/at-spi2-examples , which work well and
are very short.  But ATK servers are involved.

Will do.  Thanks again.
