3.2.71 key-signature-interface

A group of accidentals, to be printed as signature sign.

User-settable properties:

alteration-alist (association list (list of pairs))

List of (pitch . accidental) pairs for key signature.

alteration-glyph-name-alist (association list (list of pairs))

An alist of key-string pairs.

flat-positions (list)

Flats in key signatures are placed within the specified ranges of staff positions. The general form is a list of pairs, with one pair for each type of clef, in order of the staff position at which each clef places C: (alto treble tenor soprano baritone mezzosoprano bass). If the list contains a single element it applies for all clefs. A single number in place of a pair sets accidentals within the octave ending at that staff position.

non-default (boolean)

Set for manually specified clefs and keys.

padding (dimension, in staff space)

Add this much extra space between objects that are next to each other.

padding-pairs (association list (list of pairs))

An alist of padding pairs for key signatures (and key cancellations). Each alist entry has the form 

((left-glyph-name . right-glyph-name) . dist)

specifying the padding dist between two adjacent key signature elements. If there is no entry in the alist for a given pair, the padding value given by the padding property of the KeySignature (or KeyCancellation) grob is used instead.

A special feature is the handling of adjacent naturals (to be more precise, the handling of glyph accidentals.natural): If there is no ‘natural-natural’ entry in padding-pairs explicitly overriding it, LilyPond adds some extra padding (in addition to the grob’s padding value) to avoid collisions.

sharp-positions (list)

Sharps in key signatures are placed within the specified ranges of staff positions. The general form is a list of pairs, with one pair for each type of clef, in order of the staff position at which each clef places C: (alto treble tenor soprano baritone mezzosoprano bass). If the list contains a single element it applies for all clefs. A single number in place of a pair sets accidentals within the octave ending at that staff position.

Internal properties:

c0-position (integer)

An integer indicating the position of middle C.

This grob interface is used in the following graphical object(s): KeyCancellation and KeySignature.
