3.1.72 MetronomeMark

MetronomeMark objects are created by: Metronome_mark_engraver.

Standard settings:

after-line-breaking (boolean):

ly:side-position-interface::move-to-extremal-staff

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

break-align-symbols (list):

'(time-signature)

A list of symbols that determine which break-aligned grobs to align this to. If the grob selected by the first symbol in the list is invisible due to break-visibility, we will align to the next grob (and so on). Choices are left-edge, ambitus, breathing-sign, clef, staff-bar, key-cancellation, key-signature, time-signature, and custos.

break-visibility (vector):

#(#f #t #t)

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

direction (direction):

1

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.

non-break-align-symbols (list):

'(paper-column-interface)

A list of symbols that determine which NON-break-aligned interfaces to align this to.

outside-staff-horizontal-padding (number):

0.12

By default, an outside-staff-object can be placed so that is it very close to another grob horizontally. If this property is set, the outside-staff-object is raised so that it is not so close to its neighbor.

outside-staff-padding (number):

0.5

The padding to place between this grob and the staff when spacing according to outside-staff-priority.

outside-staff-priority (number):

1000

If set, the grob is positioned outside the staff in such a way as to avoid all collisions. In case of a potential collision, the grob with the smaller outside-staff-priority is closer to the staff.

self-alignment-X (number):

-1

Specify alignment of an object. The value -1 means left aligned, 0 centered, and 1 right-aligned in X direction. Other numerical values may also be specified.

side-axis (number):

1

If the value is X (or equivalently 0), the object is placed horizontally next to the other object. If the value is Y or 1, it is placed vertically.

skyline-horizontal-padding (number):

0.2

For determining the vertical distance between two staves, it is possible to have a configuration which would result in a tight interleaving of grobs from the top staff and the bottom staff. The larger this parameter is, the farther apart the staves are placed in such a configuration.

stencil (stencil):

ly:text-interface::print

The symbol to print.

vertical-skylines (pair of skylines):

#<unpure-pure-container #<primitive-procedure ly:grob::vertical-skylines-from-stencil> >

Two skylines, one above and one below this grob.

X-offset (number):

#<simple-closure (#<primitive-generic +> #<simple-closure (#<primitive-procedure ly:break-alignable-interface::self-align-callback>) > #<simple-closure (#<primitive-procedure ly:self-alignment-interface::x-aligned-on-self>) >) >

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

Y-extent (pair of numbers):

#<unpure-pure-container #<primitive-procedure ly:grob::stencil-height> >

Hard coded extent in Y direction.

Y-offset (number):

#<unpure-pure-container #<unpure-pure-container #<primitive-procedure ly:side-position-interface::y-aligned-side> #<primitive-procedure ly:side-position-interface::pure-y-aligned-side> > #<procedure outside-staff::pure-Y-offset (grob start end)> >

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

This object supports the following interface(s): break-alignable-interface, font-interface, grob-interface, item-interface, metronome-mark-interface, self-alignment-interface, side-position-interface and text-interface.
