LilyPond Internals Reference: 3.2.87 measure-grouping-interface

### 3.2.87 `measure-grouping-interface`

This object indicates groups of beats. Valid choices for `style` are `bracket` and `triangle`.

#### User settable properties:

`height` (dimension, in staff space)

  Height of an object in `staff-space` units.

`style` (symbol)

  This setting determines in what style a grob is typeset. Valid choices depend on the `stencil` callback reading this property.

`thickness` (number)

  For grobs made up of lines, this is the thickness of the line. For slurs and ties, this is the distance between the two arcs of the curve’s outline at its thickest point, not counting the diameter of the virtual “pen” that draws the arcs. This property is expressed as a multiple of the current staff-line thickness (i.e., the visual output is influenced by changes to `Staff.StaffSymbol.thickness`).

This grob interface is used in the following graphical object(s): `MeasureGrouping`.
