3.2.114 system-start-delimiter-interface

The brace, bracket or bar in front of the system. The following values for style are recognized:

bracket: A thick bracket, normally used to group similar instruments in a score. Default for StaffGroup. SystemStartBracket uses this style.
brace: A ‘piano style’ brace normally used for an instrument that uses two staves. The default style for GrandStaff. SystemStartBrace uses this style.
bar-line: A simple line between the staves in a score. Default for staves enclosed in << and >>. SystemStartBar uses this style.
line-bracket: A simple square, normally used for subgrouping instruments in a score. SystemStartSquare uses this style.

See also ‘input/regression/system-start-nesting.ly’.

User settable properties:

collapse-height (dimension, in staff space)

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

style (symbol)

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

thickness (number)

Line thickness, generally measured in line-thickness.

This grob interface is used in the following graphical object(s): SystemStartBar, SystemStartBrace, SystemStartBracket and SystemStartSquare.
