DESCRIPTION

The ­Style type collects the font and colour information for an application or a set of items within an application.  Except when using the ­layout routines (see prefab-compound(2) and prefab-element(2)), the members of a ­Style are the only way to control the appearance of ­Prefab items.  Note that although the ‘...color’ members of ­Style in practice often refer to a literal colour (a single replicated pixel of colour), 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.
