Hi,
while manipulating stems, flags and beams I noticed something strange
about flags:
\version "2.15.20"
displayGrob =
\once \override Stem #'after-line-breaking =
#(lambda (grob)
(let* ((beam (ly:grob-object grob 'beam))
(flag (ly:grob-object grob 'flag)))
(begin
(display beam)
(display flag)
(newline))))
{ \displayGrob c'8 }
{ \displayGrob c'8[ d'] }
The first example displays: ()#<Grob Flag > (as expected, no Beam, but a flag)
The second displays: #<Grob Beam >#<Grob Item >
1. IR 3.2.109 stem-interface states: "flag (graphical (layout) object)
A pointer to a Flag object."
I would have expected: () (there is no flag!)
2. AFAIK a Grob "Item" doesn't exist. IR 3.2.49 item-interface states
only that there is a subtype of grobs called Item.
Cheers,
Harm
