Re: Access a stem’s notehead

[tisimst]

Here's the commands I was told to use (assuming "grob" is the NoteColumn):

   (let ((notes (ly:grob-object grob 'note-heads)))
     (if (ly:grob-array? notes)
         (for-each
          (lambda (note) ... do something to the NoteHead... ))))

HTH,

Abraham

Hello,

I want to write a before-line-breaking callback for stem and need the
staff-position of the associated NoteHead.  (There aren’t going to be
any chords.)  This
%%%%%
\version "2.19.35"
{
   \override Stem.before-line-breaking =
   #(lambda (grob) (format #t "~a\n"
                    (ly:grob-parent grob 0)))
   b'4
}
%%%%%
tells me that the parent is the NoteColumn. How do I retrieve the
NoteHead from the Column?

TIA, Simon
