Where can I buy commercial SWT components?

I'm looking for commercial-grade SWT components such as polished charts, grids, or layout 开发者_如何学Pythonmanagers (similar to what's available on .Net with DevExpress Charts and Grids for instance).

Do you have some pointers to provide ?

Thanks!

There are very few UI products out there for SWT. We sell an Eclipse-based application and we had to go with a Swing component for a grid and deal with the multi-threading issues because there was nothing comparable on the SWT side.
