Thread: How to write a element Listener in Java?

I am little bit confused while writing the Component Listener..!! I have tried a lot of method but none of then worked out. I want to know how to write a Component Listener in Java? Any help would be highly appreciated.

Following are the techniques of the ComponentListener Interface:

• componentHidden(ComponentEvent) - method is called after the listened-to component is hidden.

• componentMoved(ComponentEvent) - method is called after the listened-to component moves.

• componentResized(ComponentEvent) - method is called when the listened-to component's size changes.
The following is the method of the ComponentEvent Class:

• Component getComponent() - method returns the component that fired the event.
Use the code given below which is helpful for you:

Code:

private static void createAndShowGUI() {
        frame = new JFrame("TrialComponentEvent");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JComponent newContentPane = new ComponentEventDemo();
        newContentPane.setOpaque(true);
        frame.setContentPane(newContentPane);
        frame.pack();
        frame.setVisible(true);
    }
