You could use the SelectionService from your IWorkbenchWindow

code ;-)
window.getSelectionService()

Kale,

Assuming you're using a Viewer (eg TreeViewer, TableViewer) inside your
view, and that contains the things that can be selected, then you need to
set that Viewer as the selection provider for your view site.

Eg in your createPartControl() call getSite().setSelectionProvider(viewer)

How was your action created? If it's done via actionSets, you subclass
ActionDelegate which allows you to override selectionChanged(IAction
action, ISelection selection) and save the selection when it changes.
