I am new to Lilypond and extremely confused. I have been working with lilypond tablature and have managed to get everything working except one thing.
I need to add an event function that will draw something to the left or right of the last tab note head. I know how to do the drawing part using postscript, however I can't figure out how to get the extents for the current notehead.
In the music I want something like this: e'4\3\mything
In mything I need something like:
(left-x ...)
(right-x ...)
(top-y ...)
(bot-y ..)
where the x and y refer to the previous tab note head.
I currently do my drawing (to the right of the notehead) starting at x=1. This works great for single digit tablature fret numbers (e.g. '1'). However as soon as the fret number goes to double digits, x=1 draws right on top of the note head.
Can anyone out there sketch me out a generic event function (or music funtion or ???) that starts with the code needed to get the extents of the previous note/chord.
Thank you for your help!
