3.1.94 NoteColumn

An auxiliary grob to align stacked notes, stems, flags, accidentals, and other items from the same voice. See also NoteCollision.

NoteColumn objects are created by: Rhythmic_column_engraver.

Standard settings:

axes (list):
'(0 1)

List of axis numbers. In the case of alignment grobs, this should contain only one number.

bend-me (boolean):


Decide whether this grob is bent.

horizontal-skylines (pair of skylines):


Two skylines, one to the left and one to the right of this grob.

main-extent (pair of numbers):


The horizontal extent of a NoteColumn grob without taking suspended NoteHead grobs into account (i.e., NoteHeads forced into the unnatural direction of the Stem because of a chromatic clash).

skyline-vertical-padding (number):


The amount by which the left and right skylines of a column are padded vertically, beyond the Y-extents and extra-spacing-heights of the constituent grobs in the column. Increase this to prevent interleaving of grobs from adjacent columns.

vertical-skylines (pair of skylines):


Two skylines, one above and one below this grob.

X-extent (pair of numbers):


Extent (size) in the X direction, measured in staff-space units, relative to object’s reference point.

Y-extent (pair of numbers):

#<unpure-pure-container #<procedure ly:axis-group-interface::height (_)> #<procedure ly:axis-group-interface::pure-height (_ _ _)> >

Extent (size) in the Y direction, measured in staff-space units, relative to object’s reference point.

This object supports the following interface(s): axis-group-interface, bend-interface, grob-interface, item-interface, note-column-interface and separation-item-interface.

This object is of class Item (characterized by item-interface).
