Question

I have used the Netbeans GUI Designer to come up with a JFrame and I wish to pass in two JPanels to the 2 dummy JPanels already placed inside the JFrame using the Netbeans GUI Designer.

However, the code below doesn’t work and the JFrame comes up blank. Why is that so?

 public Summary_Page(JPanel jp1,JPanel jp2) {

    initComponents();
    this.jp1=jp1;
    this.jp2=jp2;
    this.setVisible(true);

}

Answer 1

If this method is inside the class which extends JFrame, then just add the following line inside the Summary_Page() method:

this.add(panel);
