Yes.  Traits UI and Chaco are all compatible with Qt4.  Just set your

Yes.  We have a large number of examples.  Every screenshot in the

I'm still working on the docs (as always), but you can see them in-

The QuickStart is a good place to start, and you can find the PDF of

You can also ask specific questions on the enthought-dev or chaco-
