LilyPond Internals Reference: 3.1.2 AccidentalCautionary

### 3.1.2 `AccidentalCautionary`

A cautionary accidental, normally enclosed in parentheses.

`AccidentalCautionary` objects are created by: `Accidental_engraver`.

Standard settings:

`after-line-breaking` (boolean):

  `ly:accidental-interface::remove-tied`

  Dummy property, used to trigger callback for `after-line-breaking`.

`alteration` (number):

  `accidental-interface::calc-alteration`

  Alteration numbers for accidental.

`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`.

`extra-spacing-width` (pair of numbers):

      '(-0.2 . 0.0)

  In the horizontal spacing problem, we pad each item by this amount (by adding the ‘car’ on the left side of the item and adding the ‘cdr’ on the right side of the item). In order to make a grob take up no horizontal space at all, set this to `(+inf.0 . -inf.0)`.

`glyph-name` (string):

  `accidental-interface::calc-glyph-name`

  The glyph name within the font.

  In the context of (span) bar lines, glyph-name represents a processed form of `glyph`, where decisions about line breaking, etc., are already taken.

`horizontal-skylines` (pair of skylines):

  `#<unpure-pure-container #<procedure ly:accidental-interface::horizontal-skylines (_)> >`

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

`parenthesized` (boolean):

  `#t`

  Parenthesize this grob.

`stencil` (stencil):

  `ly:accidental-interface::print`

  The symbol to print.

`vertical-skylines` (pair of skylines):

  `#<unpure-pure-container #<procedure ly:grob::vertical-skylines-from-stencil (_)> #<procedure ly:grob::pure-simple-vertical-skylines-from-extents (_ _ _)> >`

  Two skylines, one above and one below this grob.

`X-offset` (number):

  `ly:grob::x-parent-positioning`

  The horizontal amount that this object is moved relative to its X-parent.

`Y-extent` (pair of numbers):

  `#<unpure-pure-container #<procedure ly:accidental-interface::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): `accidental-interface`, `accidental-switch-interface`, `font-interface`, `grob-interface`, `inline-accidental-interface` and `item-interface`.

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