And I know this is not what you ask for, but if you need to track
application usage, I suggest you to have a look at thoses carbons
events.
kEventAppLaunched:
kEventAppTerminated:
kEventAppFrontSwitched:
It may avoid you to check the frontmost application using a timer, or
some other (nasty) pulling method. I know this is a Carbon call, but I
don't think there is a Cocoa equivalent for the "front switched" event
(and it's available in the 64 bits API).
You can easily use them from a Cocoa Application. Just register a
event handler, and then it will be called when one of those event
occured. (if this is from a daemon application, you will have to call -
[NSApp run], else it will run automatically).
EventTypeSpec eventTypes[] = {
{ kEventClassApplication, kEventAppLaunched },
{ kEventClassApplication, kEventAppTerminated },
{ kEventClassApplication, kEventAppFrontSwitched },
};
InstallApplicationEventHandler(yourCallBackFunction,
GetEventTypeCount(eventTypes), eventTypes, self, NULL);

This will give you an NSDictionary with a lot of information about
the active application:
[[NSWorkspace sharedWorkspace] activeApplication];

Im sure this is not the right list, but it is the closest one i
could think of for this topic (or maybe carbon-dev).
I am looking to obtain the current foreground application. The
applications path, bundle identifier, or application name would be
fine, however the path would be ideal. I want to do this to track
application usage for statistical purposes for a product somewhat
similar to Altiris's Application Metering on windows. How could i
go about doing this? Also how could i deal with scenarios where
there may be more than one foreground application such as if Spaces
or Fast User Switching is enabled?
