import java.awt.BorderLayout;
import java.awt.Choice;

import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;

import javax.swing.JPanel;


public class Α2P4 extends Applet {
        Choice c1,c2;
        JPanel p1;
        public void init()
          {
                this.setLayout(new BorderLayout());
        c1=new Choice();
        c1.addItemListener(new ItemListener() {
                 
              public void itemStateChanged(ItemEvent e)
              {
                      int cm=c1.getSelectedIndex();
                            if (cm ==0)
                            setBackground(Color.red);

                            if (cm==1 )
                            setBackground(Color.blue);

              public void itemStateChanged(ItemEvent e)
              {
                  repaint();

    c2.add("FilledOval");
    p1=new JPanel();
    p1.setLayout(new FlowLayout());
    p1.setSize(200,200);
    p1.add(c2);
    p1.add(c1);
    this.add(p1,BorderLayout.PAGE_START);
   
          }
        public void paint(Graphics g){
                super.paint(g);
                g.setColor(Color.cyan);
                int c3=c2.getSelectedIndex();
                if(c3==0)
                {
                        g.drawLine(0, 50, 50, 50);
                }
        if(c3==1)
        {
                        g.drawRect(this.getWidth()/2, this.getHeight()/2, this.getWidth()/3, this.getHeight()/3);
                }
        if(c3==2)

what do you mean with "big string"? your list are added in a jpanel with a flowlayout, so when the first list has a big string the width is also enlarged and the second list should be wrapped to an other line. to fix this problem, you should use a layout with a fix size ex. Gridlayout.

If you try to replace the string item "FillRect" with "FilledRectangle" you will see that a list does not show up!Give it a chance and run the program if you have some time!

ok for demostration purposes i inserted a button in the applet called replace and i used the following code as actionlistener

Code:

---

        replace.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                        c2.remove(3);
                        c2.insert("FilledRectangle", 3);
                }
        });

---

the code is clear, the element with the index 3 is removed and then the new one is inserted. when you push the button and reopen the list, quess what you will see?
