3.2.103 spanner-interface

Some objects are horizontally spanned between objects. For example, slurs, beams, ties, etc. These grobs form a subtype called Spanner. All spanners have two span points (these must be Item objects), one on the left and one on the right. The left bound is also the X reference point of the spanner.

User settable properties:

normalized-endpoints (pair)

Represents left and right placement over the total spanner, where the width of the spanner is normalized between 0 and 1.

minimum-length (dimension, in staff space)

Try to make a spanner at least this long, normally in the horizontal direction. This requires an appropriate callback for the springs-and-rods property. If added to a Tie, this sets the minimum distance between noteheads.

spanner-id (string)

An identifier to distinguish concurrent spanners.

to-barline (boolean)

If true, the spanner will stop at the bar line just before it would otherwise stop.

Internal properties:

spanner-broken (boolean)

Indicates whether spanner alignment should be broken after the current spanner.
