Get a list of opened windows cocoa

Question

I'm new to Cocoa and I want to know how I can get a list of all open windows. I'm not talking about running programs, since this would be an easy task. I want to list windows, for example, if I have Preview running with 10 pdf opened, my program should be able to retrieve a list with all those pdf. I also want to know if there's some API available to interact with already open windows (and maybe move them or do something else) from an external application. Thank you.

Answer 1

First, Cocoa is not an acronym, so it's not "COCOA". :-)

Second, your only (public API) option is the Accessibility API. You'll have to enable access for assistive devices in the Accessibility panel in Systems Preferences.

Take a look at the docs to get started: Accessibilty Overview
