Google Web Toolkit Incubator
The Google Web Toolkit (GWT) Incubator fosters additional widgets and libraries for GWT before they are added to the core toolkit. The project is managed by the GWT engineering team at Google, and is used as a place to share, discuss, and vet future or speculative GWT features. Future releases of GWT may or may not use these features, but you are welcome to pull them from here to use today.
Downloads
The most current incubator jar can be downloaded here. All gwt-incubator source is contained in a single jar file for convenience.
Documentation
See the gwt-incubator documentation to learn more about the current set of widgets and libraries.
For specific API documentation, please see the API class reference (Javadoc)
