paper-column-interface

Paper_column objects form the top-most X-parents for items. The are two types of columns: musical columns, where are attached to, and non-musical columns, where bar-lines, clefs etc. are attached to. The spacing engine determines the X-positions of these objects.

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.

User settable properties:
between-cols (pair)
Where to attach a loose column to
between-system-string (string)
string to dump between two systems. Useful for forcing page breaks.
shortest-playing-duration (moment)
The duration of the shortest playing here.
shortest-starter-duration (moment)
The duration of the shortest note that starts here.
when (moment)
Global time step associated with this column happen?
Internal properties:
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.

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