Hi joar
As is often the case, I though of the solution within twenty minutes of
posting the question. Subclassing NSApplication was the idea I came up
with. However, since I had a notion that this might be inadvisable,
it's nice to have it validated.
Just for the archive, I might add that it's necessary in this case to
check that the event is a keyDown or mouseDown before handling it,
since -sendEvent: picks up *all* events, including mouseMoved events
when the application is in the background.
Thanks,
-Jeremy

I'm trying to implement a timed inactivity lockout in my application,
so that if there are no key or mouse events for a set period of time,
the application locks the user out, requiring a password to unlock.
Since I don't want to have to subclass every window in the application
and override -keyDown: and -mouseDown: in each of them, is there a way
to catch all key and mouse events at one point in the responder chain?
If not, can anyone suggest a better way of handling this sort of
inactivity timeout?
