/**
* Instances of this class provide a selectable user interface object
* that displays a hierarchy of items and issues notification when an
* item in the hierarchy is selected.
*
* The item children that may be added to instances of this class
* must be of type TreeItem.
*
* Style VIRTUAL is used to create a Tree whose
* TreeItems are to be populated by the client on an on-demand basis
* instead of up-front. This can provide significant performance improvements for
* trees that are very large or for which TreeItem population is
* expensive (for example, retrieving values from an external source).
*
* Here is an example of using a Tree with style VIRTUAL:
*
* final Tree tree = new Tree(parent, SWT.VIRTUAL | SWT.BORDER);
* tree.setItemCount(20);
* tree.addListener(SWT.SetData, new Listener() {
* public void handleEvent(Event event) {
* TreeItem item = (TreeItem)event.item;
* TreeItem parentItem = item.getParentItem();
* String text = null;
* if (parentItem == null) {
* text = "node " + tree.indexOf(item);
* } else {
* text = parentItem.getText() + " - " + parentItem.indexOf(item);
* }
* item.setText(text);
* System.out.println(text);
* item.setItemCount(10);
* }
* });
*
* Note that although this class is a subclass of Composite,
* it does not normally make sense to add Control children to
* it, or set a layout on it, unless implementing something like a cell
* editor.
*
*
* - Styles:
* - SINGLE, MULTI, CHECK, FULL_SELECTION, VIRTUAL, NO_SCROLL
* - Events:
* - Selection, DefaultSelection, Collapse, Expand, SetData, MeasureItem, EraseItem, PaintItem
*
*
* Note: Only one of the styles SINGLE and MULTI may be specified.
*
* IMPORTANT: This class is not intended to be subclassed.
*
*
* @see Tree, TreeItem, TreeColumn snippets
* @see SWT Example: ControlExample
* @see Sample code and further information
* @noextend This class is not intended to be subclassed by clients.
