It seems not, they are not clickable. I'm calling the function with \override Tie.stencil = #arced-curve-stencil which is defined as #(define (arced-curve-stencil grob) ... and returns the result of a (ly:stencil-translate (ly:make-stencil call. > >> Is that even possible, as I'm not actually dealing with the grob >> anymore (isn't it)? >> >> I know how to get the location from inside the ties and slurs I'm >> dealing with, but I don't know how I can get this information back >> into the resulting element in the PDF. > With stencils, you should not need to do anything.

As usual the information about ly:engraver-make-grob on the Scheme-functions page doesn't help me very much. All I would be able to figure out is the cause, but what kind of "engraver instance" should I be referring to here? -- u...@openlilylib.org https://openlilylib.org http://lilypondblog.org _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
