Eclipse RCP : Sorting JFace Viewer contents

The JFace viewer contents can be sorted by assigning them a ViewerSorter.

viewer.setSorter(new MyViewerSorter());

public class MyViewerSorter extends ViewerSorter
{
@Override
   public int compare(Viewer viewer, Object o1, Object o2)
   {
         return o1.toString().compareToIgnoreCase(o2.toString());
   }
}

This will sort the elements in alphabetical order.
