Hibernate, JFace and Virtual Table or Tree [message #305373]

Hi

I am investigating how to use virtual tables or trees in such a manner
that I can lazy load from the db and possible cache using Hibernate. My
RCP is layered, meaning I do have a POJO based domain model with DAO to
access the db and the JFace part is encapsulted too.

Any thoughts, comments, experience, articles?

Hi,

as long you are not adding/removing/inserting values into virtual tables
there's no problem using JFace, if you plan to use the functions
mentionned above I would not use Virtual-Tables together with JFace at
the moment.

org.eclipse.jface.viewers.ILazyContentProvider
org.eclipse.jface.viewers.ILazyTreeContentProvider

For tables there are also:
org.eclipse.jface.viewers.deferred.DeferredContentProvider
org.eclipse.jface.viewers.deferred.SetModel

Does http://www.eclipse.org/articles/Article-SWT-Virtual/Virtual- in-SWT.html
help, in particular listing 2? It's a very simple and generic swt-level
example, but is meant to demonstrate an approach to doing what you're asking
about.
