sorry - disregard the statement about shape notes. You should write a note-head::calc-style function in Scheme, which returns a symbol. This function should look at the pitch of the of the causing event to determine the shape to be returned. Look at accidental-interface::calc-alteration to see how to get to the causing event. You probably can bypass the entire solfa note head mechanism.
good luck Han-Wen 2007/5/9, Kevin Dalley <[EMAIL PROTECTED]>:
I have to admit that I'm stuck here. I see some documentation for gros here: http://lilypond.org/doc/v2.11/Documentation/user/lilypond-internals/grob_002dinterface#grob_002dinterface but I don't know where to start. Do you have a suggested URL?
