Root Pane Containers - The Definitive Guide to Java Swing - page 248

These constructors cascade in such a way that each adds a parameter to another constructor.
With no arguments, the created JInternalFrame has no title and can't be resized, closed,
maximized, or iconified. Internal frames can always be dragged, however.

■ Note In addition to your creating a JInternalFrame directly, you can rely on the JOptionPane to

create an internal frame for common pop-up dialog boxes hosted by a JInternalFrame instead of being
hosted by the standard JDialog .

JInternalFrame Properties
The 30 different properties for the JInternalFrame class are listed in Table 8-9. The layer property
is listed twice as it has two setter methods, one for an int and another for an Integer .
