Class TableCombo
- All Implemented Interfaces:
org.eclipse.swt.graphics.Drawable
public class TableCombo
extends org.eclipse.swt.widgets.Composite
TableCombo was written to allow the user to be able to display multiple columns of data in the "Drop Down" portion of the combo.
Special Note: 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
