I am writting an application which must know when a window is resized or moved. I had a look on notifications but it seems it does not do what I expected.
Do you have any idea how I can achieve this?
A:
Give your window a delegate. The NSWindowDelegate protocol has windowWillResize:toSize: and windowWillMove: methods.

Does it work for all windows? I mean not only the one from the application?

A:
Given your response to Carl's answer, I'd suggest the Accessibility API, which can give you access (and I believe frame change notifications) for all windows, not just your app's.

It's a good idea unfortunatly, notifications are raised when thing are done and not during moving or resizing :(

It is unfortunately the best you can do for other applications' windows.

A:
If you want window size/ordering then take a look at CGWindow.h. CGWindowListCreateDescriptionFromArray() is probably what you want.
NSWindowList() is also useful for a list of windows.
