Add a component dynamically at runtime to an applet ??

Hi,
how to add a Component (Label ...) dynamically at runtime to an applet ? I've tried various possibilities, but I haven't had any success.
Thanks, Felicitas

I guess your are trying to added components when an event ocuurs. this should be more or less the same way you add components to the Applet. Make sure that you have a specific layout and components are not overlapped.

Hi,
if I do so, I don't see my added components. I only see them, after clicking the 'restart' button in the AppletViewer.
... what's the matter ??

felicitas,
I think the reason you are not seeing the new Label is you are not updating the Applet correctly. Maybe the example below will help.

import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
public class Test extends Applet
{
    Button button;
    Label label;
    public void init()
    {
        button = new Button("push to see label");
        label = new Label("I'm a label.");
        button.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent ae){
                if(label.isVisible())
                {
                    label.setVisible(false);
                    button.setLabel("push to see label");
                }
                else
                {
                    label.setVisible(true);
                    button.setLabel("push to hide label");
                }
                validate();
            }
        });
        add(button);
        add(label);
        label.setVisible(false);
    }
}
