The scaladoc of enumerations only appear as "Value" and in the hover just show scala.Enumeration.Value and not the actual enumeration class. For this to be useful, it needs to show the specific enumeration object.
scala.swing.ScrollBar has 'def orientation: Value' and users must guess about which enumeration is required. Should have a link to ScrollBar.Orientation in the docs. Compare this to how JavaDoc provides direct links to the specific enums: http://java.sun.com/javase/6/docs/api/javax/swing/JList.html#setDropMode%28javax.swing.DropMode%29
