I want to automate this instead of having to do a lot of mouse clicking and dragging. This issue has come up a few times recently: I want to do X on my own computer! I should be able to do it! Philosophically this is a very reasonable point. Practically, however, there's no easy way to let you do whatever you want with your machine while simultaneously preventing other applications from doing the same things. Under the current model, every application you run is given equal permissions. (Yes, they can drop permissions or be put into a sandbox, but fundamentally the Unix process model assigns one effective UID and one effective GID to each process, and all processes that have the same EUID and EGID behave the same way.) Keep this in mind when filing bugs about exposing private API or access to operating system features. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

It might be all just built into the internal workings of the window manager process.

Well, at least I now know that can do what I want, albeit kludgily: I can find out the current Space as described in the earlier message here. And although there's no Cocoa nor CoreServices way for me to switch Spaces, I can at least do that via Apple Events in a sort-of hacky way: in the Spaces Preference Pane, I can map keystrokes to the Switch Directly Into a Space events, and then I can use Apple Events in my application to send these keystrokes. None of this is ideal, of course, but it's workable and acceptable for my purposes.

Re: Controlling Spaces and retrieving information about the current Space?
There is very little external control over Spaces. Be sure to file enhancement request radars. So far we have the following: 1) In 10.6 you can ask a window whether or not it is on the active Space ( [NSWindow isOnActiveSpace]) 2) CGWindow.h allows you to query for the space id (kCGWindowWorkspace) that a window is on. Note that this key is only present on visible windows. The API that you use is CGWindowListCreateDescriptionFromArray this API is slow (I saw a lot of time spent in XML decoding on 10.5), so try to use it as little as possible 3) When you create a new document window (and show it), it is placed on the active Space Combine these as needed. For example, to determine whether or not a (candidate) window is on the active Space on 10.5, I ended up doing: - Creating a new 1 by 1 document window show it. Use #2 to get its space id. I now have the id of the active space. (dispose of the window) - Get the space id for the candidate window compare with the id calculated above Obviously this is not desirable code, but this is all we have at the current point in time.

So again I beg the indulgence of all of you if there are one or more other locations where the answer to my question can be easily found. I actually have two related questions. They both pertain to the Spaces application in Snow Leopard. Is there a way in Cocoa to programmatically query which Space the user is currently looking at?
