destroying a window

[Adrian Feiguin <feiguin magnet fsu edu>]

If the user destroys a window, I'd like to save its current position
using gdk_window_get_position/origin. But if I connect
the "destroy" or "unrealize" signals, the widget->window does not exist
anymore, I only can get the size from  widget->allocation, but not the
position. Any idea?
Thanks
