How do I get window number from CFTypeRef in cocoa?

Question

CFTypeRef focusedWindow;
AXUIElementCopyAttributeValue(
        frontMostApp, kAXFocusedWindowAttribute, (CFTypeRef *)&focusedWindow
);

in this case, How do I get window number from focusedWindow?

Window number is like [[NSApp mainWindow] windowNumber]

A CFTypeRef is just a generic CF object; it's the counterpart to Foundation's NSObject. You cannot expect just any CFType to have a window number, because that doesn't make sense for most objects. An AXWindow or AXUIElement might, but, well, Chuck already said it. — Peter Hosey, Jan 20 '11 at 15:34

It's an AXUIElement, and unfortunately, you can't get its window number AFAIK.

Thank you. The link is the good source to me to understand structure of Accessibility APIs :) – Hwansoo Kim Jan 20 '11 at 07:02
