This will work:
@Override
public void onFocus(FocusEvent event) {
TextBox tb = (TextBox) event.getSource();
Element td = DOM.getParent(tb.getElement());
Element tr = DOM.getParent(td);
Element body = DOM.getParent(tr);
int row = DOM.getChildIndex(body, tr);
System.out.println("=" + row + " " + tb.getText());
}
