Old but annoying problem

Question

Hi,
I try to intercept the componentShown and componentHidden events from a JPanel in the following way:
class MyPanel extends JPanel {
    public MyPanel() {
        // panel code here
        // registering a component listener
        this.addComponentListener(new ComponentAdapter() {
            public void componentShown(ComponentEvent e) {
                System.out.println("Shown");
            public void componentHidden(ComponentEvent e) {
                System.out.println("Hidden");
}Is there a reason why this doesn't work?
Is there a way to overcome this problem?
Thanks,
Shai

Answer 1

shown or hidden is when the component becomes visible or invisible :
if you use setVisible(...) on this component.
