Calyxo Web Application Framework encourages in MVC model 2 based web application development.

It offers support for true modular applications, i18n, a flexible view manager, a powerful validation engine, and more! Calyxo is entirely written in Java and builds on the latest Servlet and JSP technologies.

The Calyxo project divides into several components

Calyxo Base - this component collects some of the basic, reusable classes used throughout all the other components. It introduces basic concepts like modules, i18n, accessors and so on...

Calyxo Control - this component implements the Calyxo controller. Calyxo uses an approach similar to Struts here, so Struts users should feel familiar with Calyxo from the start. Calyxo Control may be considered as the "main part" of the Calyxo platform.

Calyxo Forms - this component allows the definition of forms, along with all their validation steps and lets you map inputs to properties of a data object. Complex validations, dependencies between inputs and mapping an input to a set of properties are supported. The Calyxo Forms JSP tag library provides replacements for HTML elements related to forms.

Calyxo Panels - this component allows the definition of pages in a container/component manner. Pages are dynamically composed from a tree of page fragments. Panel definitions may be nested to arbitrary depth and may use inheritance.

Calyxo Struts - this component focuses on integrating Calyxo parts into the very popular Apache Struts framework. The Calyxo Panels and Calyxo Forms components may be used with Struts to replace Struts Tiles and the Struts Validator.

ASNMTAP::Asnmtap::Applications is a Perl module that provides a nice object oriented interface for ASNMTAP Applications.

ASNMTAP::Asnmtap::Applications Subclass of ASNMTAP::Asnmtap

This version is still the old ASNMTAP Applications v3.000.001 addapted for using with the new ASNMTAP::Asnmtap, ASNMTAP::Asnmtap::Plugins and ASNMTAP::Asnmtap::Plugins::Nagios plugins.

We are working onto an new Object Oriented version for the ASNMTAP Applications

Fluxspace blends Fluxboxs window management with new desktop management capabilities. The project leverages existing components and the power of Python to help build a flexible desktop environment around Fluxbox and other lightweight window managers.
Main features:
- Add per-workspace desktop icons and panels to Fluxbox by integrating tools like Rox Filer and Idesk.
- Decorate each workspace with different wallpaper.
- Manage your startup applications.
- Automatically start and stop applets as you enter and leave workspaces, allowing each workspace to have its own unique tools and dockapps.

Dynamic Taste Detection patch makes XMMS adapt its playlist randomization function to your personal taste.

Songs you dont like end up at the end of the playlist, and songs you like to hear together tend to end up next to each other.

OpenThought is a Web Application Environment which doesnt require page reloads.

SYNOPSIS

use OpenThought();

my $o = OpenThought->new( $OP );

my $field_data;
$field_data->{myTextBox} = "Text Box Data";
$field_data->{myCheckbox} = "true";
$field_data->{myRadioBtn} = "RadioBtnValue";
$field_data->{mySelectList} = [
[ "text1", "value1" ],
[ "text2", "value2" ],
[ "text3", "value3" ],
];

my $html_data;
$html_data->{id_tagname} = "New HTML Code";

print $o->serialize({
fields => $field_data,
html => $html_data,
focus => "myTextBox",
javascript => $javascript_code
});

OpenThought is a powerful and flexible web application environment. OpenThought applications are different from other web applications in that all communication between the browser and the server is performed in the background. This gives a browser the ability to receive data from the server without ever reloading the currently loaded document. Data received can be displayed automatically on the existing page, can access JavaScript functions and variables, and can load new pages. Additionally, OpenThought completely manages all of your session data for you. These features give the look and feel of a full-blown application instead of just an ordinary Web page.

OpenThought is extended with OpenPlugin, also described briefly in this documentation.

OpenThought works by communicating with the server through the use of a hidden frame. Now some may say "Frames? Youre using frames??" No need to fret though, the frame is completely hidden. There is no visible way for your users to tell that they are using an application which makes use of frames.

This hidden frame performs all communication with the server for you, and allows your browser to talk to the server without reloading the content currently visible in your web browser. This is how OpenThought can update portions of the screen, and how the server can run JavaScript code in the browser, all without reloading the page.

Any time an OpenThought application is loaded, a unique session id is generated for that user. Each time communication takes place between the browser and server, OpenThought is careful to make sure that this session id is sent along with the request. There is nothing you need to do to make this work, it is done for you. When youre programming your application, you can always expect a session id to be sent to the server, and you can easily retrieve it along with the rest of the data sent by the browser.

In addition to being able to update portions of a screen, you can also load new pages within the content frame. If you choose to load new pages, your session continues to be maintained.

OpenThought gives you an easy way of tieing together multiple web pages, and allows you to build web applications which act like "real" applications. When an application is required, some people would decide to build it in Tk, Visual Basic, Gtk, or any number of other systems which offer a visual interface. But then, your application is either not available on the web, or you have to create a seperate web interface to interact with the backend.

Have you ever tried to create a web interface which minics the interface of a non-web based application? The web based application no longer looks or acts like your other interface, it acts like an ordinary webpage. It probably uses several screens to get the same amount of content that your application offered in one.

By not ever needing to reload the page, OpenThought offers this application look and feel thats been missing from the web. This allows you to create just one interface, for both LAN and web use.
