Does a grob-type always have the same set of parent-types?
For example, does an Accidental grob always have X-parent
AccidentalPlacement and Y-parent NoteHead? If so, could this
information be incororated into the IR? It took me a while
before I was able to figure this sort of thing out:
________________System__________________
| | | | |
| | | | |
| | NonMusicalPaperColumn |
| | \ \ |
| | \ VerticalAlignment
\ \ \ /
PaperColumn VerticalAxisGroup
/ \ / /
/ X /
/ / \ /
/ / NoteColumn
\ / / \
AccidentalPlacement | |
\ \ /
\ NoteHead
\ /
Accidental
And that's the ancestry for just one grob!
I assume that a comprehensive visual "parent-web" demonstrating
all such relationships would be too convoluted to have any
practical value, and too difficult to generate to even justify
trying such a thing (although I've seen some impressive examples,
like http://www.visualthesaurus.com/). But, I imagine it should be
(at the very least) possible to have something like this near the
top of each node within IR 3.1 All layout objects:
X and Y parents: AccidentalPlacement and NoteHead.
But I don't know if the parents can change in different contexts.
If not, then does anyone have an idea how this could be generated?
Thanks.
