3.1.95 StaffGrouper

StaffGrouper objects are not created by any engraver.

Standard settings:

staff-staff-spacing (list):

'((space . 9) (stretchability . 5) (minimum-distance . 7) (padding . 1))

When applied to a staff-group’s StaffGrouper grob, this spacing alist controls the distance between consecutive staves within the staff-group. When applied to a staff’s VerticalAxisGroup grob, it controls the distance between the staff and the nearest staff below it in the same system, replacing any settings inherited from the StaffGrouper grob of the containing staff-group, if there is one. This property remains in effect even when non-staff lines appear between staves. The alist can contain the following keys:

padding – the minimum required amount of unobstructed vertical whitespace between the two items, measured in staff-spaces.
space – the vertical distance, measured in staff-spaces, between the reference points of the two items when no collisions would result, and no stretching or compressing is in effect.
minimum-distance – the smallest allowable vertical distance, measured in staff-spaces, between the reference points of the two items, when compressing is in effect.
stretchability – a unitless measure of the dimension’s relative propensity to stretch. If zero, the distance will not stretch (unless collisions would result).

staffgroup-staff-spacing (list):

'((space . 10.5) (stretchability . 9) (minimum-distance . 8) (padding . 1))

The spacing alist controlling the distance between the last staff of the current staff-group and the staff just below it in the same system, even if one or more non-staff lines exist between the two staves. If the staff-staff-spacing property of the staff’s VerticalAxisGroup grob is set, that is used instead. See staff-staff-spacing for a description of the alist structure.

This object supports the following interface(s): grob-interface, spanner-interface and staff-grouper-interface.
