JInternalFrame style: Not Resizable, Not Closable, Not Maximizable, Not Iconifiable

The JInternalFrame is hidden when first created.

Listening to InternalFrameListener

 public void internalFrameIconified(InternalFrameEvent internalFrameEvent) {
   JInternalFrame source = (JInternalFrame) internalFrameEvent.getSource();
   System.out.println("Iconified: " + source.getTitle());
 }
 public void internalFrameDeiconified(InternalFrameEvent internalFrameEvent) {
   JInternalFrame source = (JInternalFrame) internalFrameEvent.getSource();
   System.out.println("Deiconified: " + source.getTitle());
 }

} public class InternalFrameIconifyListenerSample {

 public static void main(final String[] args) {
   JFrame frame = new JFrame();
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   JDesktopPane desktop = new JDesktopPane();
   JInternalFrame internalFrame = new JInternalFrame("Can Do All", true, true, true, true);
   InternalFrameListener internalFrameListener = new InternalFrameIconifyListener();

// Add listener for iconification events

   internalFrame.addInternalFrameListener(internalFrameListener);
   desktop.add(internalFrame);
   internalFrame.setBounds(25, 25, 200, 100);

   frame.add(desktop, BorderLayout.CENTER);
   frame.setSize(500, 300);

Rules of Using Internal Frames

1. You must set the size of the internal frame.
2. You should set the location of the internal frame.

Dialogs that are internal frames should be implemented using JOptionPane or JInternalFrame, not JDialog. To create a simple dialog, you can use the JOptionPane showInternalXxxDialog methods.

Internal frames fire internal frame events, not window events.
