public final class CCombo
extends org.eclipse.swt.widgets.Composite

The CCombo class represents a selectable user interface object that combines a text field and a list and issues notification when an item is selected from the list.

Note that although this class is a subclass of Composite, it does not make sense to add children to it, or set a layout on it.

Styles:
BORDER, READ_ONLY, FLAT
Events:
Selection
