3.1.10 BalloonText

A balloon text with a pointing line to visually mark and annotate another grob.

BalloonText objects are created by: Balloon_engraver.

Standard settings:

after-line-breaking (boolean):

ly:balloon-interface::remove-irrelevant-spanner

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

annotation-balloon (boolean):

#t

Print the balloon around an annotation.

annotation-line (boolean):

#t

Print the line from an annotation to the grob that it annotates.

break-visibility (vector):

#<program 708576c38ac0 708575217034>

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

extra-spacing-width (pair of numbers):
'(+inf.0 . -inf.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).

stencil (stencil):

ly:balloon-interface::print

The symbol to print.

text (markup):

#<program 708576c38a80 708575201ab0>

Text markup. See Formatting text.

thickness (number):

1.0

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).

vertical-skylines (pair of skylines):

#<unpure-pure-container #<program 7085766234d0 27287f38> #<program 708576623690 27287e78> >

Two skylines, one above and one below this grob.

X-extent (pair of numbers):

ly:balloon-interface::width

Extent (size) in the X direction, measured in staff-space units, relative to object’s reference point.

X-offset (number):

#<program 708576c38a60 708575201ab0>

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

Y-extent (pair of numbers):

#<unpure-pure-container #<program 70857659c130 27275608> #<program 708576557180 27272fa0> >

Extent (size) in the Y direction, measured in staff-space units, relative to object’s reference point.

Y-offset (number):

#<program 708576c38a40 708575201ab0>

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

This object supports the following interface(s): accidental-switch-interface, balloon-interface, font-interface, grob-interface, sticky-grob-interface and text-interface.

This object can be of either of the following classes: Item (characterized by item-interface) or Spanner (characterized by spanner-interface). It supports the following interfaces conditionally depending on the class: item-interface and spanner-interface.
