Obtaining information about the application that owns the active window

Question

I am sure it's something easy, and I am not looking to the right documentation.

I need to get information about the application that handles the active window. The code I need to write needs to intercept some custom gestures, and return to the application an event that depends from the application itself.

Answer 1

There's the NSWorkspace class from which you can get a dictionary with information about the activeApplication. That application usually owns the "key" window.
