java - 单击按钮打开新屏幕或页面(java-eclipse)

Question

我有一个带有标题和一些按钮的主页，当我单击按钮时，我无法打开新窗口。这是我为主页以及下一个屏幕的类提供的代码，我试图打开修剪过的相关内容。 NewTicketWindow 类也已附加，目前它很简单。如有任何帮助，我们将不胜感激。

public class Home
{    

private JFrame frame;
JInternalFrame internalFrame;

/**
 * Launch the application.
 */
public static void main(String[] args)
{
    EventQueue.invokeLater(new Runnable()
    {
        public void run()
        {
            try
            {
                Home window = new Home();
                window.frame.setVisible(true);
            }
            catch (Exception e)
            {
                e.printStackTrace();
            }
        }
    });
}

/**
 * Create the application.
 */
public Home()
{
    initialize();
}

/**
 * Initialize the contents of the frame.
 */
private void initialize()
{
    frame = new JFrame();
    frame.setBounds(100, 100, 450, 300);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JLabel title1 = new JLabel("City of Murphy");

    JLabel title2 = new JLabel("Traffic Ticket Input System");

    JButton newTicketButton = new JButton("New Ticket");
    newTicketButton.addActionListener(new ActionListener()
    {
        public void actionPerformed(ActionEvent e)
        {

        }

    });

    JButton payTicketButton = new JButton("Make a Payment");

    JButton reportButtton = new JButton("Ticket Report");

    JButton exitButton = new JButton("Exit");
    GroupLayout groupLayout = new GroupLayout(frame.getContentPane());
}

二等舱(我想在按下新票按钮时打开的屏幕

public class NewTicketWindow extends JFrame
{

private JPanel contentPane;

/**
 * Launch the application.
 */
public static void main(String[] args)
{
    EventQueue.invokeLater(new Runnable()
    {
        public void run()
        {
            try
            {
                NewTicketWindow frame = new NewTicketWindow();
                frame.setVisible(true);
            }
            catch (Exception e)
            {
                e.printStackTrace();
            }
        }
    });
}

/**
 * Create the frame.
 */
public NewTicketWindow()
{
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(100, 100, 450, 300);
    contentPane = new JPanel();
    contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    setContentPane(contentPane);

    JLabel lblEnterNewTicket = new JLabel("Enter New Ticket Information");
    GroupLayout gl_contentPane = new GroupLayout(contentPane);

}

只需将这些行添加到您的操作执行代码中 -

NewTicketWindow frame = new NewTicketWindow();
frame.setVisible(true);
