       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 readability:

               $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

       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::" namespace.

       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"

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

               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 ).
