public class TableViewerExample { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); shellsetText("Table Viewer Example"); shellsetBounds(100, 100, 325, 200); shellsetLayout(new FillLayout()); final TableViewer tableViewer = new TableViewer( shell, SWTSINGLE | SWTFULL_SELECTION); final Table table = tableViewergetTable(); tablesetHeaderVisible(true); tablesetLinesVisible(true); String[] columnNames = new String[] { "First Name", "Last Name", "Age", "Num Children"}; int[] columnWidths = new int[] { 100, 100, 35, 75}; int[] columnAlignments = new int[] { SWTLEFT, SWTLEFT, SWTCENTER, SWTCENTER}; for (int i = 0; i < columnNameslength; i++) { TableColumn tableColumn = new TableColumn(table, columnAlignments[i]); tableColumnsetText(columnNames[i]); tableColumnsetWidth(columnWidths[i]); } tableViewersetLabelProvider( new PersonTableLabelProvider()); tableViewersetContentProvider( new ArrayContentProvider()); tableViewersetInput(Personexample()); shellopen(); while (!shellisDisposed()) { if (!displayreadAndDispatch()) displaysleep(); } displaydispose(); } }
After creating the table viewer, the column headers and lines are made visible by calling the setHeaderVisible() and setLinesVisible() methods in the table viewer s underlying table Four columns are then added to the table with different alignments The header text and width of each column are set with the setText() and setWidth() methods (see Section 78, Auto-sizing Table Columns, on page 348)

The label provider is set using the setLabelProvider() method and the content provider is set with the setContentProvider() method The label provider, PersonTableLabelProvider, returns a text label for each column in the table and does not return an icon The class looks like this:
import orgeclipsejfaceviewers*; import orgeclipseswtgraphics*; public class PersonTableLabelProvider extends LabelProvider implements ITableLabelProvider { public Image getColumnImage(Object element, int index) { return null; } public String getColumnText(Object element, int index) { Person person = (Person) element; switch (index) { case 0 : return personfirstName; case 1 : return personlastName; case 2 : return IntegertoString(personage); case 3 : return IntegertoString(personchildrenlength); default : return "unknown " + index; } } }
518 TreeViewer class
The TreeViewer class wraps the Tree widget A tree viewer displays a hierarchical list of objects in a parent child relationship This viewer needs to be configured with label and content providers The CheckboxTreeViewer enhances this further by adding support for graying out individual items and toggling on and off an associated checkbox with each item Useful APIs include:
add(Object, Object) Adds the given child element to this viewer as a child of the given parent element add(Object, Object[]) Adds the given child elements to this viewer
