I've released GChart 2.4, which features greatly improved hover feedback, click event support, and more.

With this release, you can define what pops up when you hover over a point  by specifying an HTML "hover template" with embedded ant-like parameters that GChart will expand relative to the hovered over point. Use built-in parameters like ${x} and ${y} or define your own by implementing the new HoverParameterInterpreter interface. The Chart Gallery has an example that displays a moving 7-row window of data, centered on the hovered-over point, that uses this technique.
If you need more control than HTML templates can provide, any GWT Widget can be turned into a "hover widget" by implementing the new HoverUpdateable interface. Since a GChart is aGWT Widget, that means you can have, say, a pie chart that moves along with your mouse, displaying changing details about the hovered over bar (the updated live demo does just that). See the Chart Gallery for examples of using Buttons, Radio Button Groups, and (modeless) DialogBoxes as hover widgets.

Release notes

The first final version of GWTEventService was exactly released yesterday (2008-12-31). Version 0.9 was really near to be final. In version 1.0 we integrated some improvements like optimized logging and some bug fixes with low priority. The manual and developer guide for GWTEventService 1.0 have been completed and got for example new chapters for deployment, building with Apache Ant and a new FAQ chapter. The developers may be glad about the more comfortable build scripts and the new build / deploy script for the demo application to deploy it to other web servers.

Unlike most of the other frameworks, GwtPHP is a framework for both client and server part. In GwtPHP you don’t need to hack JavaScript, you work with modern, object oriented languages. User intefrace (client) is programmed in Java, then compiled by Google Web Toolkit (GWT) to browser-dependent JavaScript. Server part uses PHP 5 - the most used web scripting language today.

In France, I'm trying to convince the PHP community that GWT is not about Java. It is about having a powerful and friendly client site technology. They start to be receptive to this message. This kind of product will help me to spread the word :-).

GWT Mosaic is a widget library for RIA application based on the standard GWT widgets and event model, and, is also based on the gwt-dnd libary for all drag & drop operations. GWT Mosaic is not an alternative to the GWT's widgets, it tries to extend GWT by providing new widgets like the layout managers or use widgets from other frameworks like GWT Incubator's glasspanel, date picker, tables, trees and more.
The LayoutPanel (which extends GWT's AbsolutePanel) is the corner stone for most of the widgets that are implemented. LayoutPanel is using absolute positioning to layout widgets instead of relying on HTML layout. So far, three layout managers are implemented: FillLayout, BoxLayout and BorderLayout. Another very important widget that is missing from GWT standard widget set is the WindowPanel. WindowPanel is based on GWT's DecoratedPopupPanel and is using gwt-dnd for the moving and resizing.
The goal is to provide a complete widget set by keeping the API as close as possible to the GWT's standard widgets API.
GWT Mosaic is licensed under Apache 2.0 like GWT/GWT Incubator and gwt-dnd.

With Google Chrome release, Didier Girard announces on onGWT : "the browser is the platform".

But the platform is not dead yet. For instance, GWT in the AIR just released its Milestone 1 version. A quick reminder: the aim of this project is to allow the development of AIR applications, i.e. desktop applications running on top of the Adobe AIR runtime, from GWT code.

GWT in the AIR makes the Adobe AIR API available for GWT using JSNI. This project also provides tools to ease "GWT in Adobe AIR" development includint test tools. The weakness of this project is its lack of documentation but it seems to be progressing. For the moment, the showcase and Adobe AIR documentation should be your starting points.

Ext GWT 1.1 is right around the corner and incorporates the popular Portal and Web Desktop interface.

Demos are helpful for "selling" GWT to customers.

The goal of this project is to develop an extensible platform to enable xmpp communications in gwt applications. We're happy to announce the first public release that includes the emite XMPP library, a complete instant messaging, presence and multi-user chat implementation, and a ready to use, full featured chat and rooms user interface built using extjs and gwt-ext. This is a pure-gwt (no server side code) xmmp library, so it can scale as much as your infrastructure can do. We hope gwt community finds this library useful to build other xmpp based services.
