2 JApplets in One

Question

Hello I want to ask this: I have 1 Japplet working, this JApplet build some parameters that need the 2nd Applet, so my question is how can I pass the parameters to the 2nd applet and start the 2nd applet in the same screen of the first (without closing the first, becouse when the 2nd applet end have to return to the first applet), there is a way to do this?
Thanks very much

Answer 1

let's say you have 2 simple applets (based on panels)
applet1
import java.awt.*;
import javax.swing.*;
public class TestApplet extends JApplet
  public void init()
    setContentPane(new AppletPanel1());
class AppletPanel1 extends JPanel
  public AppletPanel1()
    setPreferredSize(new Dimension(400,300));
    add(new JLabel("Applet 1"));
}applet2
import java.awt.*;
import javax.swing.*;
public class TestApplet extends JApplet
  public void init()
    setContentPane(new AppletPanel2());
class AppletPanel2 extends JPanel
  public AppletPanel2()
    setPreferredSize(new Dimension(400,300));
    add(new JLabel("Applet 2"));
}now put them together as a cardlayout, and switch between 1 and 2
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TestApplet extends JApplet
  public void init()
    JPanel holdingPanel = new JPanel(new BorderLayout());
    final CardLayout cl = new CardLayout();
    final JPanel cardlayoutPanel = new JPanel(cl);
    cardlayoutPanel.add("1",new AppletPanel1());
    cardlayoutPanel.add("2",new AppletPanel2());
    JButton btn = new JButton("Switch Panels");
    btn.addActionListener(new ActionListener(){
      public void actionPerformed(ActionEvent ae){
        cl.next(cardlayoutPanel);
    holdingPanel.add(cardlayoutPanel);
    holdingPanel.add(btn,BorderLayout.SOUTH);
    getContentPane().setLayout(new GridBagLayout());
    getContentPane().add(holdingPanel,new GridBagConstraints());
class AppletPanel1 extends JPanel
  public AppletPanel1()
    setPreferredSize(new Dimension(400,300));
    add(new JLabel("Applet 1"));
class AppletPanel2 extends JPanel
  public AppletPanel2()
    setPreferredSize(new Dimension(400,300));
    add(new JLabel("Applet 2"));
}
