3.1.50 KeySignature

KeySignature objects are created by: Key_engraver.

Standard settings:

avoid-slur (symbol):

'inside

Method of handling slur collisions. Choices are inside, outside, around, and ignore. inside adjusts the slur if needed to keep the grob inside the slur. outside moves the grob vertically to the outside of the slur. around moves the grob vertically to the outside of the slur only if there is a collision. ignore does not move either. In grobs whose notational significance depends on vertical position (such as accidentals, clefs, etc.), outside and around behave like ignore.

break-align-anchor (number):

ly:break-aligned-interface::calc-extent-aligned-anchor

Grobs aligned to this break-align grob will have their X-offsets shifted by this number. In bar lines, for example, this is used to position grobs relative to the (visual) center of the bar line.

break-align-symbol (symbol):

'key-signature

This key is used for aligning and spacing breakable items.

break-visibility (vector):

#(#f #f #t)

A vector of 3 booleans, #(end-of-line unbroken begin-of-line). #t means visible, #f means killed.

glyph-name-alist (list):

'((0 . accidentals.natural) (-1/2 . accidentals.flat) (1/2 . accidentals.sharp) (1 . accidentals.doublesharp) (-1 . accidentals.flatflat) (3/4 . accidentals.sharp.slashslash.stemstemstem) (1/4 . accidentals.sharp.slashslash.stem) (-1/4 . accidentals.mirroredflat) (-3/4 . accidentals.mirroredflat.flat))

An alist of key-string pairs.

non-musical (boolean):

#t

True if the grob belongs to a NonMusicalPaperColumn.

space-alist (list):

'((time-signature extra-space . 1.15) (staff-bar extra-space . 1.1) (right-edge extra-space . 0.5) (first-note fixed-space . 2.5))

A table that specifies distances between prefatory items, like clef and time-signature. The format is an alist of spacing tuples: (break-align-symbol type . distance), where type can be the symbols minimum-space or extra-space.

stencil (stencil):

ly:key-signature-interface::print

The symbol to print.

Y-offset (number):

ly:staff-symbol-referencer::callback

The vertical amount that this object is moved relative to its Y-parent.

This object supports the following interface(s): break-aligned-interface, font-interface, grob-interface, item-interface, key-signature-interface and staff-symbol-referencer-interface.
