Sorry, I don't know it. Could you explain ?

I don't know every incubator widgets (actually, I only know the
slider), but I am almost sure there is a lot of features. The main
point which makes me using a third-party library is I don't need (and
we didn't have the time anyway when we had to choose) to write some
custom styles in my project. The new GWT themes are unfortunately
still not enough for me, because you still have to manage HTML/CSS
positioning/sizing issues and the themes are very light.
