Thread: Action Listener in a static method

So I am trying to make a button that opens a new frame.

The problem is that my main method is static so I can't put an action listener in the main part. I assume that I can make another class to make the action listener. So far I have this:

public class VertexAdd extends JPanel implements ActionListener {
	JButton button;
 
	public VertexAdd() {
		super(new BorderLayout());
		[U]Main.AddVert.addActionListener(this);[/U]
	}
 
	public void actionPerformed(ActionEvent e) {
		createAndShowGUI();
	}
 
	private static void createAndShowGUI() {
        //Create and set up the window.
        JFrame frame = new JFrame("FrameDemo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
        JLabel emptyLabel = new JLabel("");
        emptyLabel.setPreferredSize(new Dimension(175, 100));
        frame.getContentPane().add(emptyLabel, BorderLayout.CENTER);
 
        //Display the window.
        frame.pack();
        frame.setVisible(true);
    }
}

It doesn't work right now and I am not sure how to make it so the action listener works. The button I want to attach it to is in my main class called 'AddVert'

There isn't an exception. Its just that nothing is happening. The frame should pop up once I press the button but it does nothing.

Your program design is a bit strange. It suggests that your Main class has static GUI components which you should almost never do. I suggest you re-think your design, that you get rid of everything static other than the main method, the createAndShowGUI method and perhaps some constants -- that's it.
