Can one know if a windows i minimized?

[Preben Randhol <randhol+gtk pvv org>]

I know this may be out of the realm of GTK, but since one can remove
window decorations from GTK I was wondering if one also could hook the
minimize button so the program knows that it is being minimized. This is
useful in some areas.

Thanks in advance.
