3.1.120 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-politeOne 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 asleft-to-right-greedy, but from right to left.right-to-left-polite– Same asleft-to-right-polite, but from right to left.skyline-horizontal-padding(number):
1.0For 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-skylinesTwo skylines, one above and one below this grob.
X-extent(pair of numbers):
ly:axis-group-interface::widthExtent (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.
