3.2.89 measure-spanner-interface

A bracket aligned to a measure or measures.

User-settable properties:

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 #f 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.

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).

padding (dimension, in staff space)

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

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.

spacing-pair (pair)

A pair of alignment symbols which set an object’s spacing relative to its left and right BreakAlignments.

For example, a MultiMeasureRest will ignore prefatory items at its bounds (i.e., clefs, key signatures and time signatures) using the following override:

\override MultiMeasureRest.spacing-pair =
             #'(staff-bar . staff-bar)

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).

This grob interface is used in the following graphical object(s): MeasureSpanner.
