From Frank Appel:


Deferred fetching of content should not be confused with lazy loading of elements using the SWT.VIRTUAL flag. While there are similarities between both approaches, virtual table and trees are generally useful for partial on-demand loading of large datasets.

Deferred loading is helpful for reasonable sized datasets, which nevertheless might be time consuming to retrieve and therefore would block the UI thread. Consider fetching of remote data for example. And in case you wonder, both approaches are of course mutally exclusive…
