spaceable-grob-interface

A layout object that takes part in the spacing problem.

User settable properties:

measure-length (moment)

Length of a measure. Used in some spacing situations.

penalty (number)

Penalty for breaking at this column. 10000 or more means forbid linebreak, -10000 or less means force linebreak. Other values influence linebreaking decisions as a real penalty.

Internal properties:

ideal-distances (list)

(obj . (dist . strength)) pairs.

left-neighbors (list of grobs)

List of spacing-wish grobs that are close to the current column.

The closest spacing-wishes determine the actual distances between the columns.

minimum-distances (list)

list of rods, that have the format (obj . dist).

right-neighbors (list of grobs)

see left-neighbors

spacing-wishes (list of grobs)

List of note spacing or staff spacing objects.
