3.1.116 System

System objects are not created by any engraver.

Standard settings:

axes (list):
'(0 1)
List of axis numbers. In the case of alignment grobs, this should contain only one number.
outside-staff-placement-directive (symbol):

'left-to-right-polite

One of four directives telling how outside staff objects should be placed.

left-to-right-greedy – Place each successive grob from left to right.
left-to-right-polite – Place a grob from left to right only if it does not potentially overlap with another grob that has been placed on a pass through a grob array. If there is overlap, do another pass to determine placement.
right-to-left-greedy – Same as left-to-right-greedy, but from right to left.
right-to-left-polite – Same as left-to-right-polite, but from right to left.

skyline-horizontal-padding (number):

1.0

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.

vertical-skylines (pair of skylines):

ly:axis-group-interface::calc-skylines

Two skylines, one above and one below this grob.

X-extent (pair of numbers):

ly:axis-group-interface::width

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

Y-extent (pair of numbers):

#<unpure-pure-container #<primitive-procedure ly:system::height> #<primitive-procedure ly:system::calc-pure-height> >

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

This object supports the following interface(s): axis-group-interface, grob-interface, outside-staff-axis-group-interface, spanner-interface and system-interface.
