The GWT team announced a while back that most of the stuff in the GWT incubator would be moving to GWT proper (including the powerful new cell widgets) and the incubator project would no longer be supported. One of my favorite widgets, the SliderBar, has not yet been moved over. It looks like someone has posted an incubator jar for 2.2, but before I realized that, I extracted the SliderBar from the incubator code, simplified the resource packaging a bit, and updated all the deprecated classes to work with 2.2. It’s not implemented as a Cell so probably won’t play nice with CellTables, but it’s otherwise functional. You can find the code in my listwidget sample project.
To use it in your project, just pull in the source or export it as a jar and remember to put the following in your gwt.xml file:
<inherits name='com.google.gwt.gen2.gen2'/>
Happy sliding!
