Google Web Toolkit Incubator

The Google Web Toolkit Incubator project is deprecated and is no longer supported by the GWT team.

Most of the important widgets and APIs made their way into GWT trunk a long time ago. The rest may be included at a later date.

Status of incubator APIs:

API	Equivalent in GWT trunk	Comments
Logging	java.util.logging	Logging Dev Guide
StyleInjector	ClientBundle and CssResource
Graphics	HTML5 Canvas Widget
SoundResource	HTML5 Audio Widget
Validation	Editor framework

Status of incubator Widgets:

Incubator Widget	Equivalent in GWT trunk	Comments
PagingScrollTable	DataGrid	Introduced in GWT 2.4
GlassPanel	PopupPanel.setGlassEnabled(boolean)
FastTree	CellTree
DatePicker	DatePicker
SliderBar		We may add the HTML5 Range Input in a future release
ProgressBar		We may add the HTML5 Progress Element in a future release
CollapsiblePanel		There is no replacement for CollapsiblePanel, but LayoutPanels allow you to create your own
Drop Down List Box		Not planned at this time, but some people use a vertical MenuBar to achieve the same effect
Spinner		Not planned at this time

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.

We encourage the creation of separate projects on Google Code, in the spirit of GIN and gwt-dnd.

Downloads

The most current incubator jar can be downloaded here. All gwt-incubator source is contained in a single jar file for convenience.
