问题
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?

This works fine for me. But after an other
_panel.revalidate();
_panel.repaint();
