Hi all,
I'm new to java applets. This is basically my first bigger applet. It works 100% fine when I run it in the applet viewer. As soon I start it in a web browser it stops working half way through. The code below is a short version of my applet. Its easier to understand and it reproduces what I see. Run it in the applet viewer first and than in a web-browser. I tried it in Firefox and internet explorer. Can anyone reproduce it and tell me how to fix that.
applet code:
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JApplet;
import javax.swing.JButton;
import javax.swing.JComboBox;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class ConfigApplet extends JApplet implements ActionListener{
private String str;
private JButton button;
private JLabel l;
private JComboBox box;
JPanel p;
public void init(){
p = new JPanel();
str = getParameter("text1");
if(str == null){
str = "abc";
}
p.setLayout(null);
Font font = new Font("TimesRoman", Font.BOLD, 24);
setFont(font);
button = new JButton("Change String");
button.setBounds(50, 100, 150, 30);
button.addActionListener(this);
p.add(button);
l = new JLabel(str);
l.setBounds(50, 50, 300, 30);
p.add(l);
String[]choices = new String[2];
choices[0] = "next String";
choices[1] = "another String";
box = new JComboBox(choices);
box.setVisible(false);
box.setSelectedIndex(-1);
box.setBounds(50, 100, 150, 30);
box.addActionListener(this);
p.add(box);
Container content = getContentPane();
content.add(p);
}
public void actionPerformed(ActionEvent e) {
if(e.getSource()==button){
str = getParameter("text2");
button.setVisible(false);
box.setVisible(true);
if(str!=null){
l.setText(str);
}else{
l.setText("damn that did not work");
}
}
if(e.getSource()==box){
l.setText((String)box.getSelectedItem());
}
}
