public class Row
extends Component
implements HasStyle, HasSize, HasOrderedComponents<Row>

Row class to define rows used in a Board instance.

Each Row consists of four columns, and can contain up to four components taking one column each, or fewer components with multiple columns each as long as sum of columns stays less than or equal to four.

One row might also contain a nested row as shown in the following example:

 Board board = new Board();
 Label lbl1 = createLabel("Label 1");
 Label lbl2 = createLabel("Label 2");
 Label lbl3 = createLabel("Label 3");

 Label inner1 = createLabel("Inner 1");
 Label inner3 = createLabel("Inner 3");
 Label inner4 = createLabel("Inner 4");
 Label inner2 = createLabel("Inner 2");
 Row innerRow = new Row(inner1, inner2, inner3, inner4);
 Row outerRow = board.add(lbl1, lbl2, lbl3, innerRow);
