Free widget application software for linux

CGI::Application is a framework for building reusable web-applications.

SYNOPSIS

# In "WebApp.pm"...
package WebApp;
use base CGI::Application;

# ( setup() can even be skipped for common cases. See docs below. )
sub setup {
my $self = shift;
$self->start_mode(mode1);
$self->mode_param(rm);
$self->run_modes(
mode1 => do_stuff,
mode2 => do_more_stuff,
mode3 => do_something_else
);
}
sub do_stuff { ... }
sub do_more_stuff { ... }
sub do_something_else { ... }
1;


### In "webapp.cgi"...
use WebApp;
my $webapp = WebApp->new();
$webapp->run();

CGI::Application is intended to make it easier to create sophisticated, high-performance, reusable web-based applications. This module implements a methodology which, if followed, will make your web software easier to design, easier to document, easier to write, and easier to evolve.

CGI::Application judiciously avoids employing technologies and techniques which would bind a developer to any one set of tools, operating system or web server.

Prima::Application is root of widget objects hierarchy.

Prima::Application class serves as a hierarchy root for all objects with child-owner relationship. All toolkit objects, existing with non-null owner property, belong by their top-level parental relationship to Prima::Application object. There can be only one instance of Prima::Application class at a time.

SYNOPSIS

use Prima;
use Prima::Application;
or
use Prima qw(Application);

Prima::MainWindow-> create();

run Prima;

USAGE

Prima::Application class, and its only instance are treated specially throughout the toolkit. The object instance is contained in

$::application

scalar, defined in Prima.pm module. The application instance must be created whenever widget and window, or event loop functionality is desired. Usually

use Prima::Application;

code is enough, but $::application can also be assigned explicitly. The use syntax has advantage as more resistant to eventual changes in the toolkit design. It can also be used in conjunction with custom parameters hash, alike the general create() syntax:

use Prima::Application name => Test application, icon => $icon;

In addition to this functionality Prima::Application is also a wrapper to a set of system functions, not directly related to object classes. This functionality is generally explained in "API".

The KTA is a complete telnet and SSH application designed for use by both end-users and developers. For end-users it provides a cross-platform vt320-compatible terminal written in Java.

For developers it provides an extensible plugin API that can be used to implement automated telnet and SSH solutions in a client/server environment.

Realtime Application Interface project allows applications with strict timing constraints to be run on Linux.
A real time system is able to guarantee the timing requirements of the processes under its control.
RTAI provides an API and the necessary kernel modifications to accommodate such requirements.
Enhancements:
- Improvements were made to netrpc.
- Context switching between hard and soft real-time, handling of TSC errors, and POSIX compatibility have been improved.
- There are numerous minor bugfixes.

OpenPlugin::Application is a subclass of CGI::Application, meant to help you create reusable web applications.

SYNOPSIS

# Example from OpenThoughts Demo.pm

package Demo;
use base "OpenPlugin::Application";
sub setup {
my $self = shift;
$self->run_modes(
mode1 => init_demo,
mode2 => get_os_list,
mode3 => get_os_info,
);
$self->start_mode( mode1 );
$self->mode_param(run_mode);
}
sub init_demo { ... }
sub get_os_list { ... }
sub get_os_info { ... }
1;

# Example from OpenThoughts demo.pl

#!/usr/bin/perl -wT
use strict;
my $r = shift;
my $demo = Demo->new( PARAMS => {
config => { src => "/path/to/OpenPlugin.conf" },
request => { apache => $r },
});

$demo->run();

OpenPlugin::Application is built on Jesse Erlbaums popular CGI::Application module. OpenPlugin::Application is simply a subclass of CGI::Application. Jesse says the following about CGI::Application:

"CGI::Application is intended to make it easier to create sophisticated, reusable web-based applications. This module implements a methodology which, if followed, will make your web software easier to design, easier to document, easier to write, and easier to evolve."

How does it do this? Jesse goes on to say:

"The guiding philosophy behind CGI::Application is that a web-based application can be organized into a specific set of "Run-Modes." Each Run-Mode is roughly analogous to a single screen (a form, some output, etc.). All the Run-Modes are managed by a single "Application Module" which is a Perl module. In your web servers document space there is an "Instance Script" which is called by the web server"

The biggest difference between CGI::Application and OpenPlugin::Application is that query object they both use; one is designed to use CGI.pm, the other OpenPlugin. Generally speaking, everything in the still applies. Any differences will be noted in this document.
It is not necessary to use OpenPlugin::Application in order to build web applications using OpenPlugin. This plugin is meant to be for your convenience -- to help you structure your web applications in a manner which makes sense, and is reusable.

Keystone is a cross-platform, object oriented application framework which allows applications to be written to build on the target platforms of GNU/Linux and Win32 without modification of their source.
Keystone Application Framework implements several modern Web standards, including SVG graphics and the XUL user interface description language.
Enhancements:
- A significant development in this release is the optional use of the GDI+ (Win32) and CairoGraphics (Linux) rendering backends to render SVG content.
- In addition, support for SVG paths has been much improved with the ability to render bezier and elliptical segments.

SME Web Application Framework provides a Web application framework for small and medium-sized organizations.

SMEWebApp is a framework for constructing Web applications for SMEs (small and medium-sized enterprises, companies, institutions, and organizations). It is built on phpWebApp, and it is higher-level and more specific than phpWebApp.

It has some components that can be reused in any application (perhaps with small modifications), like hierarchical menus, user authentication, and user administration.

The aim of the project is to make Web application construction for SMEs easier than using VB.
