Indeed it seems working like that ... on the other condition that getting min,
max and step parameters were extracted in the right order (forget me !) :
<<
(|GtkHScale|
(let ((adjust
(get-mult-prop-values
(get-strm-mult-prop "adjustment" props) ())))
;;; (format t "min = ~g~%" (coerce (fifth adjust) 'double-float))
;;; (format t "max = ~g~%" (coerce (fourth adjust) 'double-float))
;;; (format t "step = ~g~%" (coerce (third adjust) 'double-float))
(setq new-widget
(gtk_hscale_new_with_range
(coerce (fifth adjust) 'double-float)
(coerce (fourth adjust) 'double-float)
(coerce (third adjust) 'double-float)))))

Perhaps should we parse again gtk-server.cfg to determine the right policy
about the choice between 'single-float or 'double-float, should-we ?

Thank you Jim. I find your package really wonderfull. As I said I'm a new
comer in clisp but I can't imagine not to have a gui tool whatever the
language one has to develop with. I've had a glance (a little more than a
glance perhaps) on all these links that CLIKI points to and found no more
than three viable possibilities (old clx/clue and "consorts", ltk, and
gtk-server). gtk-server has "ma préférence" because it is coupled with GTK2
and glade, two splendid tools with continuous activity and realises. Then
the importance of your work.
Kind regards and thanks to Peter
