public class ComboViewer extends AbstractListViewer
Combo
control or CCombo
control. This class is intended as an alternative to the JFace ListViewer
, which displays
its content in a combo box rather than a list. Wherever possible, this class attempts to behave
like ListViewer. This class is designed to be instantiated with a pre-existing SWT combo control and configured with a domain-specific content provider, label provider, element filter (optional), and element sorter (optional).
