Hi,
i have noticed something strange wrt/ \accepts behaviour.
Let's start with a minimal example: i define new Staff-like context
Foo that has red noteheads:
\layout {
\context {
\Staff
\name "Foo"
\override NoteHead.color = #red
}
}
\new Foo { c'1 }
But this doesn't work (noteheads are black, which means that instead
of a Foo a Staff is created), because no context accepts Foo. So i do
\layout {
\context {
\Score
\accepts "Foo"
}
\context {
\Staff
\name "Foo"
\override NoteHead.color = #red
}
}
\new Foo { c'1 }
This works, but i cannot put several Foos in a ChoirStaff (or a
StaffGroup, etc.), i.e.
\new ChoirStaff <<
\new Foo { c'1 }
\new Foo { c' }
>>
will not get the grouping bracket. Fine, i change the code to
\layout {
\context {
\ChoirStaff
\accepts "Foo"
}
\context {
\Staff
\name "Foo"
\override NoteHead.color = #red
}
}
\new ChoirStaff <<
\new Foo { c'1 }
\new Foo { c' }
>>
Now here's where the strangeness appears. With the above definition,
only \ChoirStaff should accept Foo, shouldn't it? But if i write
\new StaffGroup <<
\new Foo { c'1 }
\new Foo { c' }
>>
it will also work, i.e. i'll get a StaffGroup of Foos. Moreover,
\new Foo { c'1 }
(i.e. no grouping at all) also works.
Is this a bug, or a feature i don't understand?
best,
Janek
