How to reload a JPanel?

cardlayout, java, jpanel, swing

Solution

This works fine for me. But after an other

_panel.revalidate();
_panel.repaint();

Problem

I'm a java newbie... I need to know how to `reload` a `JPanel`? I extended the `JPanel` class and created a panel that will run in a `cardlayout` in an Applet. I want this panel to `reload/refresh` after the user clicks a `button` in this panel. I tried including the `revalidate`() and `repaint`() methods (methods I don't understand well) in the `ActionListener` for the button but nothing happened. Can anyone throw some light on how to correctly refresh the whole panel?
