Hello. IIUC, the reference point for the X-offset property (or any other
x-shifting property that preserves the avoid-collisions algo) is on the X-
parent grob of the grob I want to modify.
Is there a way to draw a line on this grob, so that I can visually well see
the distance that I'm going to modify?
I tried to use the ly:grob-parent function, but there's obviously some
error in the below code, as it doesn't show anything:
%%%%%%%%%%%%%%%
{
\tweak DynamicText.after-line-breaking
#(lambda (grob)
(let* ((grob-x-parent (ly:grob-parent grob 0)))
(ly:grob-set-property! grob-x-parent 'stencil
#{ \markup { \override #'(thickness . 3) \draw-line #'(0 . 3) } #})))
c'\mf
}
thanks,
P
