setSelection on virtual Tree VERY slow [message #309987]

Hi,

I'm trying to set the selection on a Virtual JFace TreeViewer (there can
be 200,000+ items in the tree). The selection is a more or less random
distribution through out the tree and can be any number of items.

The naive approach is very slow:

viewer.setSelection ( new StructuredSelection (list), false ) // or true

I was wondering if there is a "virtual" selection so that it doesn't
need to call setToWidget for every item in the selection. It could do
it when the items are being shown instead.

Do I have to implement this?

(Hope this is the correct list)

Thanks,

Jesse
