Well carved.  I understood.

Yes.  Expected.  lookup_widget() must be given another widget within
the same top level widget.

The way I solve this is to retain at least a widget pointer to my
logical parent window widget, or the button that triggered it.  In my
gfocustimer application, I have a struct for the dialog that contains
the pointer and other stuff.  There are, of course, other ways to have
the dialog remember the related widget.
