       Prima - a perl graphic toolkit


               use Prima qw(Application Buttons);

               new Prima::MainWindow(
                       text     => 'Hello world!',
                       size     => [ 200, 200],
               )-> insert( Button =>
                       centered => 1,
                       text     => 'Hello world!',
                       onClick  => sub { $::application-> close },

               run Prima;


       The toolkit is combined from two basic set of classes - core and
       external. The core classes are coded in C and form a base line for
       every Prima object written in perl. The usage of C is possible together
       with the toolkit; however, its full power is revealed in the perl
       domain. The external classes present easily expandable set of widgets,
       written completely in perl and communicating with the system using
       Prima library calls.

       The core classes form an hierarchy, which is displayed below:


       The external classes are derived from these; the list of widget classes
       can be found below in "SEE ALSO".


       The very basic code shown in "SYNOPSIS" is explained here.  The code
       creates a window with ’Hello, world’ title and a centered button with
       the same text. The program terminates after the button is pressed.

       A basic construct for a program written with Prima obviously requires

               use Prima;

       code; however, the effective programming requires usage of the other
       modules, for example, "Prima::Buttons", which contains set of button
       widgets. "" module can be invoked with a list of such modules,
       which makes the construction

               use Prima;
               use Prima::Application;
               use Prima::Buttons;

       shorter by using the following scheme:

               use Prima qw(Application Buttons);

       Another basic issue is the event loop, which is called by

               run Prima;

       sentence and requires a "Prima::Application" object to be created
       beforehand.  Invoking "Prima::Application" standard module is one of
       the possible ways to create an application object. The program usually
       terminates after the event loop is finished.

       The window is created by invoking

               new Prima::Window();


               Prima::Window-> create()

       code with the additional parameters. Actually, all Prima objects are
       created by such a scheme. The class name is passed as the first
       parameter, and a custom set of parameters is passed afterwards. These
       parameters are usually represented in a hash syntax, although actually
       passed as an array.  The hash syntax is preferred for the code

               $new_object = new Class(
                       parameter => value,
                       parameter => value,

       Here, parameters are the class properties names, and differ from class
       to class. Classes often have common properties, primarily due to the
       object inheritance.

       In the example, the following properties are set :


       Property values can be of any type, given that they are scalar. As
       depicted here, "::text" property accepts a string, "::size" - an
       anonymous array of two integers and "onClick" - a sub.

       onXxxx are special properties that form a class of events, which share
       the "new"/"create" syntax, and are additive when the regular properties
       are substitutive (read more in Prima::Object).  Events are called in
       the object context when a specific condition occurs.  The "onClick"
       event here, for example, is called when the user presses (or otherwise
       activates) the button.


       This section describes miscellaneous methods, registered in "Prima::"

       message TEXT
           Displays a system message box with TEXT.

       run Enters the program event loop. The loop is ended when
           "Prima::Application"’s "destroy" or "close" method is called.

       parse_argv @ARGS
           Parses prima options from @ARGS, returns unparsed arguments.


       Prima applications do not have a portable set of arguments; it depends
       on the particular platform. Run

               perl -e '$ARGV[0]=q(--help); require Prima'

       or any Prima program with "--help" argument to get the list of
       supported arguments. Programmaticaly, setting and obtaining these
       options can be done by using "Prima::options" routine.

       In cases where Prima argument parsing conflicts with application
       options, use Prima::noARGV to disable automatic parsing; also see
       parse_argv.  Alternatively, the construct

               BEGIN { local @ARGV; require Prima; }

       will also do.

       Class information
           The Prima manual pages often provide information for more than one
           Prima class.  To quickly find out the manual page of a desired
           class, as well as display the inheritance information, use
           "p-class" command. The command can produce output in text and pod
           formats; the latter feature is used by the standard Prima
           documentation viewer "podview" ( see File/Run/p-class ).
