3.1.141 SystemStartSquare

A rectangle-like bracket as a start delimiter.

SystemStartSquare objects are created by the following engraver(s): System_start_delimiter_engraver.

Standard settings:

collapse-height (dimension, in staff space):

5.0

Minimum height of system start delimiter. If equal or smaller, the bracket/brace/line is removed.

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.

stencil (stencil):

ly:system-start-delimiter::print

The symbol to print.

style (symbol):

'line-bracket

This setting determines in what style a grob is typeset. Valid choices depend on the stencil callback reading this property.

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).

X-offset (number):

ly:side-position-interface::x-aligned-side

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

Note that many objects have special positioning considerations, which cause any setting of X-offset to be ignored or modified, even though the object supports the self-alignment-interface.

This object supports the following interface(s): font-interface, grob-interface, side-position-interface, spanner-interface and system-start-delimiter-interface.

This object is of class Spanner (characterized by spanner-interface).
