[g-a-devel]checking Accessible* validity

[David Bolter <david bolter utoronto ca>]

Has anyone written (from the at-client perspective) a function to check 
the validity of an Accessible*?

 I think most of us clients are queueing and storing such pointers, and 
it is possible to cause badness when they are defunct.  I recently 
noticed that gedit does not seem to emit the same defunct events for the 
case where it is closed using the file - quit option as opposed to 
pressing the close box.

You should be able to confirm this using event-listener-test -m  in 
at-spi/test

So given that objects can possibly go defunct without client knowledge, 
is there a way a client can check the validity of its stored 
Accessible*?  Or is it the case that we must deal with them when we pop 
the queue and not store interfaces (e.g. Accessible*) to them longer 
than that?

cheers,
