import java.awt.event.WindowEvent;
import javax.swing.JDesktopPane;
import javax.swing.JFrame;

/**
* Internal Frames Demo

* @version $Id: JIFrameDemo.java,v 1.4 2003/07/15 01:46:47 ian Exp $
*/
public class JIFrameDemo {
/* Main View */
public static void main(String[] a) {
final JFrame jf = new JFrame("JIFrameDemo Main Window");
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
screenSize.width -= 42;
screenSize.height -= 42;
jf.setSize(screenSize);
jf.setLocation(20, 20);
JMenuBar mb = new JMenuBar();
jf.setJMenuBar(mb);
JMenu fm = new JMenu("File");
mb.add(fm);
JMenuItem mi;
fm.add(mi = new JMenuItem("Exit"));
mi.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});
JDesktopPane dtp = new JDesktopPane();
//dtp.setBackground(Color.GREEN);
jf.setContentPane(dtp);
JInternalFrame mboxFrame = new JInternalFrame("Mail Reader", true,
true, true, true);
JLabel reader = new JLabel("Mail Reader Would Be Here");
mboxFrame.setContentPane(reader);
mboxFrame.setSize(400, 300);
mboxFrame.setLocation(50, 50);
mboxFrame.setVisible(true);
dtp.add(mboxFrame);
JInternalFrame compFrame = new JInternalFrame("Compose Mail", true,
true, true, true);
JLabel composer = new JLabel("Mail Compose Would Be Here");
compFrame.setContentPane(composer);
compFrame.setSize(300, 200);
compFrame.setLocation(200, 200);
compFrame.setVisible(true);
dtp.add(compFrame);
JInternalFrame listFrame = new JInternalFrame("Users", true, true,
true, true);
JLabel list = new JLabel("List of Users Would Be Here");
listFrame.setContentPane(list);
listFrame.setLocation(400, 400);
listFrame.setSize(500, 200);
listFrame.setVisible(true);
dtp.add(listFrame);
jf.setVisible(true);
jf.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
jf.setVisible(false);
jf.dispose();
System.exit(0);
}
});
}
}
