public class CustomCombo
extends org.eclipse.swt.widgets.Composite
The CustomCombo 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.

CustomCombo was written to work around certain limitations in the native combo box. Specifically, on win32, the height of a CustomCombo can be set; attempts to set the height of a Combo are ignored. CustomCombo can be used anywhere that having the increased flexibility is more important than getting native L&F, but the decision should not be taken lightly. There is no is no strict requirement that CustomCombo look or behave the same as the native combo box.

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:
DefaultSelection, Modify, Selection, Verify
