### 3.2.139 volta-bracket-interface

Volta bracket with number.

#### User settable properties:

> `dashed-edge` (boolean)

>   If set, the bracket edges are dashed like the rest of the bracket.

> `height` (dimension, in staff space)

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

> `shorten-pair` (pair of numbers)

>   The lengths to shorten on both sides a hairpin or text-spanner such as a pedal bracket. Positive values shorten the hairpin or text-spanner, while negative values lengthen it.

> `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`).

#### Internal properties:

> `bars` (array of grobs)

>   An array of bar line pointers.

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