/**
* Instances of this class implement a selectable user interface
* object that displays a list of images and strings and issues
* notification when selected.
*
* The item children that may be added to instances of this class
* must be of type TableItem.
*
* Style VIRTUAL is used to create a Table whose
* TableItems 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 TableItem population is
* expensive (for example, retrieving values from an external source).
*
* Here is an example of using a Table with style VIRTUAL:
*
* 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 ());
* }
* });
*
*
* 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, HIDE_SELECTION, VIRTUAL, NO_SCROLL
* Note: Only one of the styles SINGLE, and MULTI may be specified.
*
* IMPORTANT: This class is not intended to be subclassed.
*
*
* @see Table, TableItem, TableColumn snippets
* @see SWT Example: ControlExample
* @see Sample code and further information
* @noextend This class is not intended to be subclassed by clients.
