ATSPI Update

Hi Frederik!

I started to work on the ATSPI plugin today and have some questions:

I didn't manage to find any real documentation - is there anything available?

When introspecting the services, I can see that there is a "role" to each 
object that tells me wheter it's a button / label / etc. which is good. 
However, I couldn't find something like doAction() to actually use that 
information for something. Is this already implemented?

And last but not least: What is the best way to find out if an object is 
currently being shown to user (to disable everything else)?

Best regards,
Peter

Ps.: I hope it's okay to use the kde-accessibility mailing list for this but I 
thought this might be interesting others as well...
