Description

The Style type collects the font and color information for an application or a set of items within an application. Except when using the layout routines (see compound - windows for ITV toolkit and element - menu and display elements for ITV toolkit), the members of a Style are the only way to control the appearance of Prefab items. Note that although the color members in practice often refer to a literal color (a single replicated pixel of color), they can be any image.

Styles are allocated by regular Limbo definitions. There is no allocation function. All the members of a Style must be defined. Although it will not cause errors to modify the members of a Style after it has been created and passed to a Prefab routine, the results may be unpredictable.
