BreakAlignment

BreakAlignment grobs are created by: Break_align_engraver

align-interface

Order grobs top to bottom/left to right/right to left etc.

stacking-dir (direction):

stack contents of grobs in which direction ?. Default value: 1

align-dir (direction):

Which side to align? -1: left side, 0: around center of width, 1: right side. Default value: (unset)

threshold (pair of numbers):

(cons MIN MAX), where MIN and MAX are dimensions in staffspace. Default value: (unset)

alignment-done (boolean):

boolean to administrate whether we've done the alignment already (to ensure that the process is done only once). Default value: (unset)

center-element (grob (GRaphical OBject)):

grob which will be at the center of the group after aligning (when using Align_interface::center_on_element). . Default value: (unset)

elements (list):

list of grobs, type depending on the Grob where this is set in. Default value: (unset)

axes (list):

list of axis numbers. In the case of alignment grobs, this should contain only one number. Default value: '(0)

axis-group-interface

a group of coupled grobs

axes (list):

list of axis numbers. In the case of alignment grobs, this should contain only one number. Default value: '(0)

general-grob-interface

All grobs support this

X-offset-callbacks (list):

list of functions, each taking an grob and axis argument. The function determine the position relative to this grob's parent. The last one in the list is called first. Default value: (unset)

Y-offset-callbacks (list):

see X-offset-callbacks. Default value: (unset)

X-extent-callback (procedure):

procedure taking an grob and axis argument, returning a number-pair. The return value is the extent of the grob. Default value: (unset)

Y-extent-callback (procedure):

see X-extent-callback. Default value: (unset)

molecule-callback (procedure):

Function taking grob as argument, returning a Scheme encoded Molecule. Default value: (unset)

font-relative-size (number):

partial font definition: the relative size compared the `normal' size. 0 is style-sheet's normal size, -1 is smaller, +1 is bigger, -1 is smaller. Default value: (unset)

extra-offset (pair of numbers):

pair of reals (a cons) forcing an extra offset before outputting. extra-offset is added just before `printing' the grob, so the typesetting engine is completely oblivious to it.

Default value: (unset)

interfaces (list):

list of symbols indicating the interfaces supported by this object. Is initialized from the meta field. Default value: (unset)

dependencies (list):

list of score-grob pointers that indicate who to compute first for certain global passes. Default value: (unset)

no-spacing-rods (boolean):

read from grobs: boolean that makes Separation_item ignore this item (MOVE ME TO ITEM). Default value: (unset)

extra-extent-X (pair of numbers):

enlarge in X dimension by this much, measured in staff space. Default value: (unset)

extra-extent-Y (pair of numbers):

see extra-extent-Y. Default value: (unset)

minimum-extent-X (pair of numbers):

minimum size in X dimension, measured in staff space. Default value: (unset)

minimum-extent-Y (pair of numbers):

see minimum-extent-Y. Default value: (unset)

origin (input location):

location in input file of the definition. Default value: (unset)

transparent (boolean):

This is almost the same as setting molecule-callback to #f, but this retains the dimensions of this grob, which means that you can erase grobs individually. . Default value: (unset)
