Hi, I would like some help, if possible
When I run my frame, the swing components donŽt appear.
Can any body tell me why is that?
Thanks, in advance.

Pedro,
You're missing a brace ending the declaration of the main() method, so
the JButton's method declaration is messed up. I'm surprised this code
will even compile.
Note: in your main() method you probably should also add the line:
frame.show();
after the construction of the frame.
Good luck,
- Jeff

Are you using an AWT Frame or a Swing JFrame as the container? Please
post a code sample that exhibits your problem.

This code shows that I am tried to create a frame with a button.
And when I run the code the ContentPane doesn't appear.
Thank you very much.
public class Myframe extends JFrame {
private javax.swing.JPanel jContentPane = null;
private javax.swing.JButton jButton = null;
/**
* This is the default constructor
*/
public Myframe() {
super();
initialize();
}
/**
* This method initializes this
*
* @return void
*/
private void initialize() {
this.setTitle("XPTO");
this.setSize(316, 250);
this.setContentPane(getJContentPane());
this.addWindowListener(new java.awt.event.WindowAdapter() {
public void windowClosing(java.awt.event.WindowEvent e) {
System.out.println("windowClosing()"); // TODO Auto-generated Event
stub windowClosing()
System.exit(0);
}
});
}
private javax.swing.JPanel getJContentPane() {
if(jContentPane == null) {
jContentPane = new javax.swing.JPanel();
jContentPane.setLayout(null);
jContentPane.add(getJButton(), null);
}
return jContentPane;
}
public static void main(String[] args) {
Myframe frame = new Myframe();
private javax.swing.JButton getJButton() {
if (jButton == null) {
jButton = new javax.swing.JButton();
jButton.setBounds(195, 65, 87, 62);
jButton.setText("OK");
jButton.setOpaque(false);
jButton.setVisible(true);
}
return jButton;
}
