I don't get this.

Oh yes, of course! And than a presentation translator to pathname that
has a tester that checks whether the buffer is grafted (if I may use
this term in analogy to the use when referred to sheets), that is the
FILEPATH slot of the CLIMACS-BUFFER instance contains a pathname.
Something like:

(define-presentation-translator climacs-buffer-to-pathname-translator
    (climacs-buffer pathname global-climacs-table
       :gesture :select
       :tester ((object)
                (filepath object))
       :tester-definitive t
       :documentation ((object stream)
                       (format stream "Select pathname ~a" (namestring (filepath object)))))
    (object)
  (filepath object))


(This is actually tested code that works as expected.)

This is really as the buffer-name, presented as of type
CLIMACS-BUFFER, will be selectable as input for FIND-FILE (if is
associated with a file) and *also* as input for SWITCH-TO-BUFFER.

That's the magic of CLIM. :-)

Well, everyone knows what is meant by "modeline". That's probably not
true for "info-pane"..

Yes, yes. Just click on "overwrite" and it will be toggled.. Also we
can use real icons in the "info-pane" and don't have to resort to
ASCII to represent the various states. Mhmm.

Bye,
Max
