April,
I've been searching through the documentation and I have yet to find
the particular service that broadcasts these events. I don't know if
applications default to broadcast when they are opened, closed, etc. I
thought the Workspace might be the place, but listening to all events
from there got me zilch. I also checked around in the Finder
documentation to see if it offered this kind of information, but all I
found was basically a wrapper to the file system.
So I suppose what I am seeking is some system level notification center
that broadcasts all these system level activities. I have yet to find
one.
Of course, the capability must exist, the Dock obviously is aware of
all these things. Anyone want to tell me how the Dock works?

Isn't it possible to write either a command line tool or small app that
would just listen for all events... I think the param you pass for the
event to watch is either nil or null, and then log the even either to
the
console or to a file or something?
The only thing I wonder is if the app would be able to log not only the
notification posted but the posting app or at least the posting class?
I was going to experiment with this but other things have consumed my
time
and so if I am right about this and it would work let me know, if not,
let
me know so I dont waste time.
Thanks

There was no response to the message quoted below. I am also
interested in learning how to do this. I'm interested in making an
app that is able to be informed when other applications are launched,
quit, activated or deactivated. Any tips?

Out of curiosity, How does one react to events in other applications?
Lets say I want the finder to play a sound when a window opens or
perhaps I'd like to know when iTunes finishes playing a track or is
completely launched. So that I can do ... Something I dunno make the
computer play a happy little flash movie, the reaction isn't
important,
It's finding out what's happening in any app or specific apps that
I'm
foggy on.
April.
