| * Instances of this class implement a selectable user interface |
| * object that displays a list of images and strings and issues |
| * notification when selected. |
| * <p> |
| * The item children that may be added to instances of this class |
| * must be of type <code>TableItem</code>. |
| * </p><p> |
| * Style <code>VIRTUAL</code> is used to create a <code>Table</code> whose |
| * <code>TableItem</code>s are to be populated by the client on an on-demand basis |
| * instead of up-front. This can provide significant performance improvements for |
| * tables that are very large or for which <code>TableItem</code> population is |
| * expensive (for example, retrieving values from an external source). |
| * </p><p> |
| * Here is an example of using a <code>Table</code> with style <code>VIRTUAL</code>: |
| * <code><pre> |
| * final Table table = new Table (parent, SWT.VIRTUAL | SWT.BORDER); |
| * table.setItemCount (1000000); |
| * table.addListener (SWT.SetData, new Listener () { |
| * public void handleEvent (Event event) { |
| * TableItem item = (TableItem) event.item; |
| * int index = table.indexOf (item); |
| * item.setText ("Item " + index); |
| * System.out.println (item.getText ()); |
| * } |
| * }); |
| * </pre></code> |
| * </p><p> |
| * Note that although this class is a subclass of <code>Composite</code>, |
| * it does not make sense to add <code>Control</code> children to it, |
| * or set a layout on it. |
| * </p><p> |
