Click and Point Issue

[Stephan Zitzmann]

I have asked this question at the frescobaldi list, but Urs Liska gave me
the advice to ask here and to forward my question and his answer.

My question:

This is a excerpt of a greater score:

\version "2.19.65"

cha = \lyricmode {
  cha -- ka -- ti -- ki

}

dak = \lyricmode {
  da -- ka -- la

}

ch = {a16 a a a}
da = {\times 2/3 {a16 a a }}


TRB = {
  \set subdivideBeams = ##t

  \set baseMoment = #(ly:make-moment 1/8)
  \set beatStructure = #'(2 2 2 2)
}

TRA = {

  \unset subdivideBeams

  \unset baseMoment
  \unset beatStructure

}

\new DrumStaff {
      \override Staff.StaffSymbol.line-positions = #'(0 )

If I am clicking on a note or  syllable in the note viewer I am landning not
at the place, where I  am using the predefinied
variable, I am landing where I definied the variables. So I have to scroll
and I am lost a little bit in the code. This is not helpfull.

Urs Liska answer:

This is an issue with LilyPond, not with Frescobaldi. The point is that the
"origin" which is saved in the graphical symbol points to the *definition*
of it and not to where you use it.

The only way I can see to overcome this is to change your variables like \ch
or \dak to Scheme functions that massage that origin. This is somewhat more
involved, and I don't see right now *how* complicated it would be and
therefore whether it would be worth the trouble.

But I suggest you repost your question (incorporating my comments) on the
lilypond-user mailing list because there are many more people who may be
able to help you.

Good luck
Urs

My personal opinion is, I do not need help. But I think it is a kind of bug.
Because of the resulting big unusibality.
