Question

I created two classes in netbeans;One of them is a JPanel form and another is a JFrame form;
How can i add the JPanel class into JFrame form class?
I wrote this code in constructor of JFrame form Class but ,it didnt work.

public JFrameClass() {
        initComponents();
        this.getContentPane().add(jpc = new JPanelClass());
        jpc.setVisible(true);
        this.pack();
        this.setVisible(true);

    }

Answer 1

set the bounds of the JPanel so that the container knows where to draw it

       public void run() {
            NewJFrame frame = new NewJFrame();
            NewJPanel panel = new NewJPanel();

            panel.setBounds(0, 0, 200, 200);
            frame.add(panel);
            frame.setVisible(true);
        }
