paper-column-interface

Paper_columns form the top-most item parent. (The Paper_columns X parent is System, which is a spanner.)

Paper_columns form the units for the spacing engine. They are numbered, the first (leftmost) is column 0. Numbering happens before line-breaking, and columns are not renumbered after line breaking.

Since many columns go unused, you should only use the rank field to get ordering information. Two adjacent columns may have non-adjacent numbers.

Don't be confused by right-items: each spacing wish can also contain a number of items, with which a spacing constraint may be kept. It's a little baroque, but it might come in handy later on?

between-cols (pair)

Where to attach a loose column to

between-system-string (string)

string to dump between two systems. Useful for forcing pagebreaks.

bounded-by-me (list of grobs)

list of spanners that have this column as start/begin point. Only columns that have grobs or act as bounds are spaced.

shortest-playing-duration (moment)

duration of the shortest playing in that column.

shortest-starter-duration (moment)

duration of the shortest notes that starts exactly in this column.

when (moment)

when does this column happen?.

This grob interface is used in the following graphical objects: PaperColumn and NonMusicalPaperColumn
