3.2.160 tuplet-bracket-interface

A bracket with a number in the middle, used for tuplets. When the bracket spans a line break, the value of break-overshoot determines how far it extends beyond the staff. At a line break, the markups in the edge-text are printed at the edges.

User-settable properties:

avoid-scripts (boolean)

If set, a tuplet bracket avoids the scripts associated with the note heads it encompasses.

bracket-flare (pair of numbers)

A pair of numbers specifying how much edges of brackets should slant outward. Value 0.0 means straight edges.

bracket-visibility (boolean or symbol)

This controls the visibility of the tuplet bracket. Setting it to false prevents printing of the bracket. Setting the property to if-no-beam makes it print only if there is no beam associated with this tuplet bracket.

break-overshoot (pair of numbers)

A pair of numbers specifying how much a broken spanner sticks out of its bounds horizontally on the broken side(s). For broken beams and broken tuplet brackets, the bounds are given by the prefatory matter on the left and/or the rightmost column on the right. For broken horizontal brackets, the bounds are the leftmost and/or rightmost column; for broken measure spanners, the left and/or right edge of the staff.

connect-to-neighbor (pair)

Pair of booleans, indicating whether this grob looks as a continued break.

dash-definition (pair)

List of dash-elements defining the dash structure. Each dash-element has a starting t value, an ending t-value, a dash-fraction, and a dash-period.

dashed-edge (boolean)

If set, the bracket edges are dashed like the rest of the bracket.

direction (direction)

If side-axis is 0 (or X), then this property determines whether the object is placed LEFT, CENTER or RIGHT with respect to the other object. Otherwise, it determines whether the object is placed UP, CENTER or DOWN. Numerical values may also be used: UP=1, DOWN=-1, LEFT=-1, RIGHT=1, CENTER=0.

edge-height (pair)

A pair of numbers specifying the heights of the vertical edges: (left-height . right-height).

edge-text (pair)

A pair specifying the texts to be set at the edges: (left-text . right-text).

full-length-padding (number)

How much padding to use at the right side of a full-length tuplet bracket.

full-length-to-extent (boolean)

Run to the extent of the column for a full-length tuplet bracket.

gap (dimension, in staff space)

Size of a gap in a variable symbol.

max-slope-factor (non-negative number)

Factor for calculating the maximum tuplet bracket slope. Notice that there exists a homonymous property for slurs.

padding (dimension, in staff space)

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

positions (pair of numbers)

Pair of staff coordinates (start . end), where start and end are vertical positions in staff-space units of the current staff. For slurs, this value selects which slur candidate to use; if extreme positions are requested, the closest one is taken.

shorten-pair (pair of numbers)

The lengths to shorten on both sides a hairpin or text-spanner such as a pedal bracket. Positive values shorten the hairpin or text-spanner, while negative values lengthen it.

span-all-note-heads (boolean)

If true, tuplet brackets are printed spanning horizontally from the first to the last note head instead of covering only the stems.

staff-padding (dimension, in staff space)

Maintain this much space between reference points and the staff. Its effect is to align objects of differing sizes (like the dynamics p and f) on their baselines.

thickness (number)

For grobs made up of lines, this is the thickness of the line. For slurs and ties, this is the distance between the two arcs of the curve’s outline at its thickest point, not counting the diameter of the virtual “pen” that draws the arcs. This property is expressed as a multiple of the current staff-line thickness (i.e., the visual output is influenced by changes to Staff.StaffSymbol.thickness).

tuplet-slur (boolean)

Draw a slur instead of a bracket for tuplets.

visible-over-note-heads (boolean)

This prints a tuplet bracket when the bracket is set to be over the note heads. This option can be combined with the default tuplet bracket visibility style and with #'if-no-beam.

X-positions (pair of numbers)

Pair of X staff coordinates of a spanner in the form (left . right), where both left and right are in staff-space units of the current staff.

Internal properties:

beam (graphical (layout) object)

A pointer to the beam, if applicable.

note-columns (array of grobs)

An array of NoteColumn grobs.

potential-beam (graphical (layout) object)

For tuplet brackets, a grob to use as parallel beam unless the tuplet is broken.

scripts (array of grobs)

An array of Script objects.

tuplet-number (graphical (layout) object)

The number for a bracket.

tuplets (array of grobs)

An array of smaller tuplet brackets.

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