    Default How to make a new screen on applet.

    Hi, Im making an applet that has a bunch of stages. The applet has a little "next" button down in the corner, and i want it to take them to the next section, however, unlike making a regular program i cant just make the next page in a seperate class and call on it from my original one... So how would i have the applet go to the next section...?
    Thanks
    Joel

    Yes, in my main applet i call on the next screen with :
            if (e.getSource()==add){
                FindApplet findapplet = new FindApplet();
            }

    and then the FindApplet class is a new applet all together...

    import java.applet.*;
    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
    public class FindApplet extends Applet implements ActionListener
    { 
        JPanel panel = new JPanel();
        JButton nextButton = new JButton("Next -->");
        JRadioButton biologyClass = new JRadioButton("Biology");
        ...more radiobuttons
        ButtonGroup classButtonGroup = new ButtonGroup();
        public void init() {
            setLayout(new GridBagLayout());
            GridBagConstraints c = new GridBagConstraints();
            //add to button group
            classButtonGroup.add(biologyClass);
            ...add them all to group
            //add to panel
            panel.add(biologyClass);
            ...add them all to panel
            //add panel to applet with constraints
            add(panel, c);
            add(nextButton, c);
     
        }
     
        public void start() { 
        }
     
        public void actionPerformed(ActionEvent e){
     
        }
     
        public void stop() {
        }
     
        public void destroy() {
        }
     
    }

    However when i click the button that should open it, nothing happens...

    There is nothing in your posted code to make anything happen when you click the button.

    Creating a new instance of an Applet will NOT display a new window.

    Add some println statements to the methods in your code to see where execution goes as the program is executed.

    I dont want it to open in a new window, i want it to clear the current screen and make the new one. I put some println and the actionlistener works fine before and after i call a new FindPage, but the printlns i put in the FindPage didnt show up...

    That means that you are not executing the println statements.
    Does your code call any of the methods in the FindPage class?
    If you create a new instance the constructor should be called. Do you have a println in the constructor?

    Have you looked at the CardLayout class? It might have features that will help you.
