Using the accessibility APIs, you'd do something like this:

- get the pid_t of an application
- call AXUIElementCreateApplication with that pid
- call AXObserverCreate with that pid
- call AXObserverAddNotification with that AXUIElementRef and observer, passing kAXMainWindowChangedNotification as the notification
- call AXObserverGetRunLoopSource on that observer
- call CFRunLoopAddSource( GetCFRunLoopFromEventLoop( GetMainEventLoop() ), passing that run loop source

Now your callback proc should be called when the main window (i.e., the active window) of that application changes.

Is it possible to use any of these APIs (or any APIs for that matter) to obtain the name of the window once I'm notified that it's become active?
thanks!
