The HTML page that we found in the previous section, describes the layout object called Fingering. Such an object is a symbol within the score. It has properties that store numbers (like thicknesses and directions), but also pointers to related objects. A layout object is also called a Grob, which is short for Graphical Object. For more details about Grobs, see grob-interface.
The page for Fingering
lists the definitions for the
Fingering
object. For example, the page says
padding
(dimension, in staff space):
0.6
which means that the number will be kept at a distance of at least 0.6 of the note head.
Each layout object may have several functions as a notational or typographical element. For example, the Fingering object has the following aspects
Each of these aspects is captured in so-called interfaces, which are listed on the Fingering page at the bottom
This object supports the following interfaces: item-interface, self-alignment-interface, side-position-interface, text-interface, text-script-interface, font-interface, finger-interface, and grob-interface.
Clicking any of the links will take you to the page of the respective object interface. Each interface has a number of properties. Some of them are not user-serviceable (“Internal properties”), but others are.
We have been talking of the Fingering
object, but actually it
does not amount to much. The initialization file
scm/define-grobs.scm shows the soul of the `object',
(Fingering . ((print-function . ,Text_interface::print) (padding . 0.6) (staff-padding . 0.6) (self-alignment-X . 0) (self-alignment-Y . 0) (script-priority . 100) (font-size . -5) (meta . ((interfaces . (finger-interface font-interface text-script-interface text-interface side-position-interface self-alignment-interface item-interface))))))
As you can see, the Fingering
object is nothing more than a
bunch of variable settings, and the webpage in the Program Reference
is directly generated from this definition.
