frmas from and applet

[petoeter]

Hi,

The aim is to write some code so , starting from an applet, the user
can a make a choice (by radio buttons and an OK button), to let pop
up
different frames.
Hereby my (simpified) code. What's wrong, no way to generate a frame?
Thanks,
(as a am a novice, all suggestions are wellcome)


import java.awt.*
import javax.swing.*;
import java.awt.event.*;


public class test extends JApplet implements ItemListener {
JRadioButton radio1;
ButtonGroup groep;
JButton knop;
int a;
public void init() {
Container contentPane = getContentPane();
contentPane.setLayout(new GridLayout(2,0));
groep = new ButtonGroup();
radio1 = new JRadioButton("test");
groep.add(radio1);
radio1.addItemListener(this);
contentPane.add(radio1);
knop = new JButton( "OK");
contentPane.add(knop);
knop.addActionListener(new ActionListener() {
public void actionPerformed (ActionEvent ev){
if (a ==1) {
frame1 one = new
frame1();
one.frame1();
}
}
});
}


public void itemStateChanged(ItemEvent e) {
if (e.getItemSelectable() == radio1){
a = 1;
}
}
}
class frame1 extends JFrame {
panel j;
public void frame1() {
Container contentPane = getContentPane();
j = new panel();
contentPane.add(j);
JTextField t;
t = new JTextField(20);
contentPane.add(t);
}
public static void main(String args[]) {
final JFrame f = new frame1();
f.setBounds(100, 100, 300, 300);
f.setVisible(true);
f.setDefaultCloseOperation(EXIT_ON_CLOSE);
f.addWindowListener(new WindowAdapter() {
public void windowClosed(WindowEvent e) {
System.exit(0);
}
});
}
}
class panel extends JPanel {
panel() {
setBackground(Color.white);
}
public void paintComponent (Graphics g) {
super.paintComponent(g);
g.drawString("Hi !!! ", 2, 60);
}
}

The JFrames are being constructed, but the
applet never calls frame.setVisible(true)
(or that other stuff in the main method of
the frame class).

Applet development is for experts and fools.
Leave it aside till much (much) later.

I do believe that the conjunction "and" is very well advised. It seems one
must be both at once to write applets.

Since I run on a 64b Linux with the provided Firefox browser, I cannot run
applets here at all, no matter how expertly or foolishly written, until
various third parties get over themselves. I am able to run Webstarted apps.

Good point, I actually meant to put 'or'.

Huh! Thanks for that.

In a conversation the other day, one of the
respondents was complaining that they preferred
applets because web start was 'not supported
on all platforms for which Java is available'
(or words to that effect).

It is good to now have the counter-point -
'neither are applets'.
