3.2.92 self-alignment-interface

Position this object on itself and/or on its parent. To this end, the following functions are provided:

Self_alignment_interface::[xy]_aligned_on_self

Align self on reference point, using self-alignment-X and self-alignment-Y.

Self_alignment_interface::aligned_on_[xy]_parent

Self_alignment_interface::centered_on_[xy]_parent

Shift the object so its own reference point is centered on the extent of the parent

User settable properties:

collision-bias (number)

Number determining how much to favor the left (negative) or right (positive). Larger absolute values in either direction will push a collision in this direction.

collision-padding (number)

Amount of padding to apply after a collision is detected via the self-alignment-interface.

self-alignment-X (number)

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.

self-alignment-Y (number)

Like self-alignment-X but for the Y axis.

Internal properties:

potential-X-colliding-grobs (array of grobs)

Grobs that can potentially collide with a self-aligned grob on the X-axis.

X-colliding-grobs (array of grobs)

Grobs that can collide with a self-aligned grob on the X-axis.

Y-colliding-grobs (array of grobs)

Grobs that can collide with a self-aligned grob on the Y-axis.

This grob interface is used in the following graphical object(s): AccidentalSuggestion, BarNumber, DoublePercentRepeatCounter, DynamicText, Fingering, GridLine, Hairpin, InstrumentName, InstrumentSwitch, LyricText, MetronomeMark, MultiMeasureRestNumber, MultiMeasureRestText, OctavateEight, PercentRepeatCounter, RehearsalMark, SostenutoPedal, StemTremolo, StringNumber, StrokeFinger, SustainPedal, TextScript and UnaCordaPedal.
