Table: set "focused" row [message #728708] Fri, 23 September 2011 17:50 Go to next message

On Windows, my SWT tables show a dotted border around the "focused" row. This seems to always be the first row initially, not matter what entry I select initially. How can I set the "focused" row to match the selected row?

I see what you're describing. I don't think this is a bug, as there
isn't necessarily a link between the selected item(s) and the focus
item. The focus item is just the place from which keyboard navigations
are resolved.

There isn't a way to set the focus item. A snippet like the one below
can be used to draw focus on an item, but windows still considers the
top item to have the logical focus. I couldn't find an existing feature
request to enable this, so if you want you can log one at
(I don't know if this is natively supported on all platforms).

public static void main(String[] args) {
final Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new GridLayout());
new Text(shell, SWT.SINGLE).setLayoutData(new GridData(100,30));
final Table table = new Table(shell, SWT.MULTI);
table.setLayoutData(new GridData(200,200));
new TableItem(table, SWT.NONE).setText("One");
new TableItem(table, SWT.NONE).setText("Two");
new TableItem(table, SWT.NONE).setText("Three");;
table.addListener(SWT.EraseItem, new Listener() {
public void handleEvent(Event event) {
int index = table.indexOf((TableItem)event.item);
if (index == 1 && table.isFocusControl()) {
event.detail |= SWT.FOCUSED;
} else {
event.detail &= ~SWT.FOCUSED;
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();

Sorry for bringing up an old post, but I encountered the same issue and found a solution. I'm putting my solution here just in case someone else finds this post.

My solution involves using an ugly work around: post mouse events that simulate a click on the item:

import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Event;
import org.eclipse.swt.widgets.Table;
import org.eclipse.swt.widgets.TableItem;
import org.eclipse.swt.widgets.Widget;

 * Utility class for tables.
 * @author Henno Vermeulen
public final class Tables {

	private Tables() {

	 * Shows and selects the table <code>item</code> and lets it get the
	 * keyboard focus.
	 * <p>
	 * Windows has a "focused" row (drawn with a dotted line) that can be moved
	 * independently of the selected row (when pressing ctrl + up/down). This
	 * method ensures that this focused row is made equal to the selected row so
	 * that the selection does not jump to an unwanted location when the user
	 * uses the up or down arrow on the keyboard.
	 * <p>
	 * Implementation detail: there is no API to get/set the focused row (see
	 * also <a href="">this
	 * post</a> and <a href=
	 * "">
	 * this one</a>), so we use a filthy hack: faking a mouse click in the
	 * table.
	public static void selectAndFocus(TableItem item) {

	private static void fakeMouseClickTableItem(TableItem item) {
		Table table = item.getParent();

		Point cursorLocation = item.getDisplay().getCursorLocation();
		fakeMouseClick(table, getCenter(item.getBounds(0)));

	private static Point getCenter(Rectangle bounds) {
		return new Point(bounds.x + bounds.width / 2,
				bounds.y + bounds.height / 2);

	 * Actually moves the mouse cursor to the given <code>location</code> so
	 * that the OS gives the correct click behavior.
	private static void fakeMouseClick(Control control, Point location) {
				.post(createMouseEvent(SWT.MouseDown, control, location));
				.post(createMouseEvent(SWT.MouseUp, control, location));

	public static Event createMouseEvent(int type, Widget widget,
			Point position) {
		Event e = new Event();
		e.display = widget.getDisplay();
		e.widget = widget;
		e.type = type;
		e.x = position.x;
		e.y = position.y;
		e.count = 1;
		e.button = 1;
		e.doit = true;
		return e;
