Designing with layouts
Design your UI in <code>null</code>
 or <code>XYLayout</code>
 using nested panels to group components. Convert panels to final layouts after you've finished assembling the components. <code>XYLayout</code>
 is a feature of JBuilder Professional and Enterprise. For a tutorial on UI design, see &quot;Creating a UI with nested layouts&quot; in <cite>Designing User Interfaces</cite>
