On Mac OS X 10.5 you can read back information on other windows within
the same GUI session as the calling process using the CGWindow API
(defined in /System/Library/Frameworks/ApplicationServices.framework/
Frameworks/CoreGraphics.framework/Headers/CGWindow.h).
/* CGWindowListCopyWindowInfo
* Copy the CFArray of CFDictionaries, with each dictionary
containing descriptive information
* on a window within the user session.
* Returns NULL if called from outside of a GUI security session, or
if no window server is running
* The returned CFArray may be empty if no windows meet the
specified criteria. */
CG_EXTERN CFArrayRef CGWindowListCopyWindowInfo( CGWindowListOption
option, CGWindowID relativeToWindow );
Each dictionary in the returned array will include a number of
interesting values. Bounds for each window can be extracted from a
dictionary in the returned array using:
CGRect boundsForWindowDictionary( CFDictionaryRef windowDictionary )
{
CFDictionaryRef rectDictionary;
CGRect rect;
rectDictionary = CFDictionaryGetValue(windowDictionary,
kCGWindowBounds);
if ( rectDictionary )
{
if ( CGRectMakeWithDictionaryRepresentation(rectDictionary, &rect) )
return rect;
}
return CGRectNull; /* Failure case */
}

Actually it would be to design some kind of "window-sensitive" VNC
server/client. Therefore I need to be able to track the window
rectangles of third-party apps. Does it helps ?

How does it work for multiple document applications ?
In the general case, I am not sure that this is possible. You may be
able to get something working by using the Accessability APIs. Post
what it is that you're actually trying to do (i.e. *why* you want to
know the locations of other application's windows) and perhaps
you'll
get a more helpful response.
