As this widgets is used heavily by the web workbench it is (almost) feature complete, though not bug free:(
!SIMPLE style is missing, and probably will be for a log time.
'Implemented' as copy-from-SWT-with-minor-changes.
Implemented. We copied the source-code from SWT and it simply works :-)
Implemented sufficiently for the web workbench to work.
A basic implementation exists. The client-side support for scroll bars is very basic and therefore are the capabilities of the current ScrolledComposite implementation.
As the current implementation reaches its barriers we can re-implement the current ScrolledComposite to use dedicated client-side scroll bars that allow more control over scrolling behavior. But nonetheless you won't have the same fine-grained control as in SWT.
A very basic implementation exists right now. As CBanner is used in the web workbench we will enhance it as required by the workbench.
