Panel added to frame is not showing up

[Erik Jansen]

Hi,

I have made an applet that displays two selection lists. After selecting a value from either of these lists and pressing a button, I'd like to show a different frame (or a panel inside the current frame) with a new interface customized to the selection.

Currently I have a class selectionPanel which looks something like this:

public class selectionPanel extends javax.swing.JPanel {
    String name;
    
    public selectionPanel(String string) {
        initComponents();
        this.name = string;
        titleLabel.setText(name);
        setVisible(true);
    }
                       
    private void initComponents() {
           auto-generated by netbeans...
    }
}

In my main class I call this method after pressing the button as follows:

selectionPanel sp = new selectionPanel(name);
add(sp);

The newly added panel is not showing up in my main frame. I've tried calling pack() or validate() (suggested in other posts) but this doesn't seem to solve the problem. Do you guys (and possibly girls) have any ideas?

It rather looks like you need to use a CardLayout.

Thanks, I'll have a look!
