Hi,

Is it possible to display a EMF model in a SWT TableViewer with the
SWT.VIRTUAL flag set? I tried a few quick google searches but didn't
come up with anything useful.

Jesper,

We've never looked into how to support that (via some type of lazy
content provider)...

Well because EMF-Lists (beside we are talking about CDO) are fully
populated all the time and you simply want the UI to get up faster you
can simply add the SWT.VIRTUAL flag and the TableItem creation is
deferred until the item is scrolled into view.

See http://wiki.eclipse.org/JFaceSnippets#Snippet029VirtualTableViewer
for an example.

But be aware that there are some known bugs in Virtual-JFace-Controls
which are not fixed and unless someone steps up and fixes them they are
very likely unfixed even after 4.2, 4.3, ... .
