So I am making a Text-Based RPG Applet in Java. I am using SWING panels, with text fields and buttons on it. I am programming it in Netbeans, and I am using the GUI editor. I have crafted the HTML page and it opens in the browser fine. When I click a button to switch panels (basically set the first the non-visible), the new panel doesn’t load. I tried using repaint() and validate() but it just doesn’t work….. Any help?
package applettest;
import javax.swing.UIManager;
public class NewApplet extends java.applet.Applet {
startScreen ss;
registerScreen rs;
charactercreationScreen ccs;
@Override
public void init() {
try {
//This sets the look and feel to NIMBUS.
UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");
} catch (Exception ex) {
ex.printStackTrace();
}
try {
java.awt.EventQueue.invokeAndWait(new Runnable() {
@Override
public void run() {
initComponents();
startup();
}
});
} catch (Exception ex) {
ex.printStackTrace();
}
}

Sounds like you should be using
CardLayout.See also:
