42  * Demonstrates the <code>FormLayout</code> with a <code>PanelBuilder</code>.
43  * Columns and rows are specified before the panel is filled with components.
44  * Unlike the {@link PlainExample} this class uses a local variable
45  * to keep track of the current row. The advantage over fixed numbers is,
46  * that it's easier to insert new rows later.
47  * <p>
48  * This panel building style is simple and works quite well. However, you may
49  * consider using a more sophisticated form builder to fill the panel and/or
50  * add rows dynamically; see the {@link DynamicRowsExample} for this alternative.
