To determine whether the app is launching for the first time, you can
put a boolean called "firstLaunch" into the user defaults. It would
have a factory default of YES and could be changed to NO inside of
applicationDidFinishLaunching:.
As for the buttons, are you sure you want to detect mouse events on
them? Will setting their targets and actions, and possibly determining
which button was clicked using the actions' "sender" arguments, not
suffice? If not, I believe you will have to subclass NSButton to
override the mouse event-handling methods.

Here's a simplification:
I have an application with several buttons. If it is the first time
the application is launching, I want to do some special things. In
my AppController class, which is a delegate of NSApp, I use the
delegate method -applicationDidFinishLaunching: to perform the test.
After I've detected that it is the first time, I first want to
access some IBOutlets. Then, I'd like to be able to get mouse events
for each button, so that I can do other things.
I can't figure out want to do with the classes. I'd like to make a
new class (FirstLaunch) for the first launch, but I'm not sure what
to call from AppDelegate. Also, to get mouse events, shouldn't I be
a sublass of the buttons, and considering that I have multiple
buttons, I'm confused. I could probably tackle these issues one-by-
one, but taken all together, they're confusing me.
Broken down, I need to access & manipulate IBOutlets I have set in
IB, determine when buttons are clicked (and which button was
clicked). I'd like to be able to do this from another class so as to
not clutter up the AppDelegate.
Thanks for the help!
