i have a problem.

I want to have a Main Panel in which will load another panel that is inside a different class.

The main panel is this:

public class ClassPanel extends JPanel {

public ClassPanel(){
    JLabel scritta = new JLabel("Which Panel");
    JButton one = new JButton("Panel 1");


    class b1Button implements ActionListener {
        public void actionPerformed(ActionEvent e) {
           GameOne gameone = new GameOne();
           add(gameone);
        }

    }

    one.addActionListener(new b1Button());

    add(scritta);
    add(one);

}}

And the class GameOne is this:

public class GameOne extends JPanel{

public GameOne() {
    JLabel lab = new JLabel("Game 1 selected");
    add(lab);
}}

The problem is that when i click the Button 1 in the main panel, i don't see the label in the GameOne class.

Whats the problem? Thanks :)

Are you sure there are no compiler errors when compiling your project? – Ferrybig Jan 22 '16 at 14:14
Yes there are no errors, or maybe Netbeans find no errors. – Simone Brigante Jan 22 '16 at 14:16
@SimoneBrigante Call the method `revalidate()` after the line containing `add(gameone)` – Naruto Biju Mode Jan 22 '16 at 14:20
@NarutoBijuMode Thank you!! Now it works! :D – Simone Brigante Jan 22 '16 at 14:23
