I need a simple MDI application...

Answer 1

This is the simplest I could come up withimport java.awt.*;
import javax.swing.*;
public class Test3 extends JFrame {
  public Test3() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    Container content = getContentPane();
    JDesktopPane jdp = new JDesktopPane();
    content.add(jdp, BorderLayout.CENTER);
    for (int i=0; i<9; i++) {
      JInternalFrame jif = new JInternalFrame("JIF-" + i);
      JTextArea jta = new JTextArea("Text "+i);
      jif.getContentPane().add(new JScrollPane(jta),BorderLayout.CENTER);
      jif.setBounds((i/3)*100,(i%3)*100,100,100);
      jif.setVisible(true);
      jdp.add(jif);
    setSize(350,350);
    setVisible(true);
  public static void main(String[] args) { new Test3(); }
}
