Free designer software for linux

Django 1.0.2 provides you with a professional and high-level Python Web framework which will encourage rapid development and clean, pragmatic design.

Major Features:

1. Object-relational mapper: Define your data models entirely in Python. You get a rich, dynamic database-access API for free but you can still write SQL if needed.
2. Automatic admin interface: Save yourself the tedious work of creating interfaces for people to add and update content. Django does that automatically, and its production-ready.
3. Elegant URL design: Design pretty, cruft-free URLs with no framework-specific limitations. Be as flexible as you like.
4. Template system: Use Djangos powerful, extensible and designer-friendly template language to separate design, content and Python code.
5. Cache system: Hook into memcached or other cache frameworks for super performance caching is as granular as you need.
6. Internationalization: Django has full support for multi-language applications, letting you specify translation strings and providing hooks for language-specific functionality.

MonoDevelop is a project to port SharpDevelop to Gtk#. There are numerous goals that MonoDevelop hopes to achieve.
Main features:
- To create a best of breed development environment for Unix systems for C# and Mono.
- Since its written in Gtk#, and we like Gtk# and we get good support from Gtk#, most likely it will add functionality to improve the Gtk# experience.
- Today the IDE is a simple IDE and on Unix does not do GUI design, but we plan on adding a GUI designer.
- We want to integrate the tools we have been building so far, so things like MonoDoc, NUnit-Gtk and the debugger should target MonoDevelop.

BFlow is a Web-based business workflow management and help desk tool. It features email and SMS notifications of tasks organized into arbitrarily complex business processes.
Main features:
- b-Flow Workflow Tool -- Offered under GPL v2, as Open Source product.
- b-Flow Workflow Tool Pro -- Commercial license only, includes additional Professional Reporting module, LDAP integration and paid support.
- Based on LAMP (Linux, Apache, MySQL, PHP), the software offers a Web-based interface with secure role-based access control and authentication. It has been developed over the past six years, and is now being offered for free use under the GNU Public License, version 2. Lanifex is pleased to offer commercial support and maintenance contracts for this software to interested companies, as well as custom development and adaptation services for organizations who wish to integrate or modify the software to meet specific needs.
- Some of the powerful features:
- Integrated graphical workflow design tool
- Notification messages via Email and SMS
- Escalation chains to trigger additional actions
- Form designer with flexible data storage
- Forms attached to requests, with drop-downs and form trees
- Export and import via XML of forms and workflow templates

Qjackctl software is a simple Qt application that can control the JACK sound server daemon, specific for the Linux Audio Desktop infrastructure.
Written in C++ around the Qt3 toolkit for X11, most exclusively using Qt Designer.
Provides a simple GUI dialog for setting several JACK daemon parameters, which are properly saved between sessions, and a way control of the status of the audio server daemon. With time, this primordial interface has become richer by including a enhanced patchbay and connection control features.
Bugs:
Probably plenty still, but qjackctl its now considered on beta stage already. It has been locally tested since JACK release 0.98.0, on SuSE 9.1, Mandrake 10.0 and Fedora Core 1, with custom 2.4 kernels with low-latency, preemptible and capabilities enabling patches. As for 2.6 kernels, the capabilities patch may also apply but the emergence of the Realtime Linux Security Module (LSM) and Ingo Molnars Realtime Preemption kernel patch its being now recommended for your taking benefit of the realtime and low-latency audio pleasure JACK can give.
Enhancements:
- An immediate showstopper crash upon client start was irradicated, which was affecting those with the system-tray icon disabled, as is the default (thanks to Ken Ellinwood for first reporting this sloppy one).

phpWebApp is an application framework which makes easy and simple the task of building PHP web applications based on relational databases. It separates the task of designing and changing the layout of the application from the task of implementing the logic of the application, by using XML templates that are an extension of XHTML.
The project also simplifies the task of implementing the logic of the application by offering an event based programming model. In addition, phpWebApp tries to offer modularity and code reusability to the community of webApp developers.
Main features:
- The framework separates the layout from the logic of the application, so a graphical designer can easily improve the layout of the application without getting messed with the logic and without having to understand it. It makes easier the work of both the graphical designer and the programer. This also facilitates an iterative and incremental development approach for web application projects.
- The framework gives the possibility to divide a page into several parts which can be used in other pages as well. This makes the user interface of the application (the layout, the graphical part) more structured and easier to understand and maintain and makes easier the work of the graphical designer.
- The framework looks at web applications from a new point of view. From this point of view, a web application is a state machine, which can be represented and described by one or more statechart diagrams. Each page of the application that is displayed, represents the application in a certain state. Clicking to a link causes a transition to another state of the application. This simplifies the design and the implementation of web applications. Later, if this point of view is formalised and elaborated enough, it may provide the theoretical bases for automatic code generation of web applications from state chart diagrams (e.g. from UML state chart diagrams), and for reverse engineering.
- The framework supports an event based programing model. When a transition from one state of the application to another happens, it may trigger an event as well, which is handled by a function (event handler). This makes the logic of the application easy to build, understand and maintain, and makes easy the work of the web programer.
- The framework gives to the web programers the possibility to create independent web components (called WebBox-es) which have their own user interface (graphical design), client side behaviour, server side behaviour, states, events, event handlers, etc. These components can be very easily reused in other web applications and thus provide code reusability to web programers. This means that if you have constructed something once, you dont have to re-construct it again when you need it another time, but use it ready.
- The framework brings closer the client-side and the server-side logic of a web application. E.g. the session variables (which are usually used to keep the state of various parts of the application), are available and can be accessed both on client side and on server side.
- The framework makes the interaction with the database almost database independent. This means that in case that you decide to change the database on which your application is based (e.g. switching from MySQL to Oracle), then the application itself doesnt need to be changed at all, it will work all the same.
Enhancements:
- Bugfixes and some improvements in documentation were made.

FryPHP project is fast and easy to learn templating engine/system for PHP5.

Why another templating system? Well... I have tried and even worked with a lot and was not happy with any of them. They all as a rule force you to learn a "new language" and its not right. I do not believe in all that designer safety and all... As my practice showed - competent enough people: HTML guys who know PHP or even programmers and surely not designers work with dynamic part of templates (of cource there are exceptions).

After working with RHTML in Ruby on Rails I found out how convenient it was. So I decided to make some templating system for PHP5, which uses plain PHP for templating.

FryPHP is written in object oriented manner using test driven development (TDD).

FryPHP allows local variables for each template, you also can set global variables. FryPHP makes use of method overloading and provides FryHelpers which save a lot of time on routineous HTML generation, such as selects generation for date selection.

FryPHP is very young project so more documentation, examples etc. are still to come.

For now, most of Frys features can be learned by reading test files.
