NAME
       Prima::Const - predefined constants

DESCRIPTION
       "Prima::Const" and Prima::Classes is a minimal set of perl modules
       needed for the toolkit. Since the module	provides bindings for the core
       constants, it is	required to be included	in every Prima-related module
       and program.

       The constants are assembled under the top-level package names, with no
       "Prima::" prefix. This violates the perl	guidelines about package
       naming, however,	it was considered way too inconvenient to prefix every
       constant	with "Prima::" string.

       This document provides description of all core-coded constants. The
       constants are also described in the articles together with the
       corresponding methods and properties. For example, "nt" constants are
       also described in "Flow"	in Prima::Object article.

   ps::	- paint	states
	       ps::Disabled    - can neither draw, nor get/set graphical properties on an object
	       ps::Enabled     - can both draw and get/set graphical properties	on an object
	       ps::Information - can only get/set graphical properties on an object

       For brevity, ps::Disabled is equal to 0 so this allows for simple
       boolean testing whether one can get/set graphical properties on an
       object.
