I think I can't use this: I don't create an ad-hoc widget, I need an
`define-widget' expression to define the widget to behave accordingly
when created.

And the widget this is about is a part of a group widget definition so
there will never be an explicit `widget-create' call by me, the widget
will always be created implicitly by the parent.

And in this definition a :value spec is more or less ignored - in my
tests that child widget will always be created with a nil widget value.

I am attaching the code in question so that you don't have to guess -
you can find the relevant part by searching for the comment

  ;; Is there a better approach, Mauro?

or simply just your name.


Thanks so far,

Michael.
