I am very happy and proud to announce prototype UI is officially open today.

At the beginning of the project, it was only a full rewrite of Prototype Window but it became quickly a UI library based on Prototype 1.6 and script.aculo.us 1.8 to include all my previous components like Prototype Carousel ....

This library is developed by Samuel Lebeau and myself. Sam worked hard on the core classes and the object design. It’s also done with help of Juriy Zaytsev and Vincent Le Moign for the design.

And I want to thank Emanuel ‘Mila76’ for his help on IE (BIG HELP) and for his div version of PWC (the new window system is based on it).

This version is only for developer and early adopters. You can only download it with subversion. The final release will be done when prototype 1.6 will be stable and of course when prototype UI too :).

You will be able to download a JS per component, a JS file with the full library and a build page will allow you to create your own JS file with UI components you need.

This goal is to build to best free UI library (under MIT licence) based on Prototype.

In the current version you have

• window
  • skinnable
  • shadowing system independent from window and skinnable
  • div based
  • resizable from all borders and corners
  • custom buttons
  • Dialogs (like it’s done in PWC) are not yet implemented but will be done soon

• carousel: only HTML content (no Ajax content)
• dock (experimental)
• shadow: a simple class to add shadow on any element with a absolute position.

Stay tuned ;) and long life to prototype UI.

Here is a sample test to see the new window system (from functional tests included in the distrib)

PS: Any feedback is really appreciated (bugs, documentation, patches, API …)
