| 45 * Instances of this class provide a selectable user interface object | |
| 46 * that displays a hierarchy of items and issues notification when an | |
| 47 * item in the hierarchy is selected. | |
| 48 * <p> | |
| 49 * The item children that may be added to instances of this class | |
| 50 * must be of type <code>TreeItem</code>. | |
| 51 * </p><p> | |
| 52 * Style <code>VIRTUAL</code> is used to create a <code>Tree</code> whose | |
| 53 * <code>TreeItem</code>s are to be populated by the client on an on-demand basis | |
| 54 * instead of up-front. This can provide significant performance improvements for | |
| 55 * trees that are very large or for which <code>TreeItem</code> population is | |
| 56 * expensive (for example, retrieving values from an external source). | |
| 57 * </p><p> | |
| 58 * Here is an example of using a <code>Tree</code> with style <code>VIRTUAL</code>: | |
| 59 * <code><pre> | |
| 60 * final Tree tree = new Tree(parent, DWT.VIRTUAL | DWT.BORDER); | |
| 61 * tree.setItemCount(20); | |
| 62 * tree.addListener(DWT.SetData, new Listener() { | |
| 63 * public void handleEvent(Event event) { | |
| 64 * TreeItem item = (TreeItem)event.item; | |
| 65 * TreeItem parentItem = item.getParentItem(); | |
| 66 * String text = null; | |
| 67 * if (parentItem is null) { | |
| 68 * text = "node " + tree.indexOf(item); | |
| 69 * } else { | |
| 70 * text = parentItem.getText() + " - " + parentItem.indexOf(item); | |
| 71 * } | |
| 72 * item.setText(text); | |
| 73 * System.out.println(text); | |
| 74 * item.setItemCount(10); | |
| 75 * } | |
| 76 * }); | |
| 77 * </pre></code> | |
| 78 * </p><p> | |
| 79 * Note that although this class is a subclass of <code>Composite</code>, | |
| 259 | 80 * it does not normally make sense to add <code>Control</code> children to |
| 81 * it, or set a layout on it, unless implementing something like a cell | |
| 82 * editor. | |
| 90 | 83 * </p><p> |
