java - 用户单击 JButton 时如何关闭 JFrame 窗口？

Question

我的节目是关于超市的。我在 delivery() 方法中创建了一个名为 b1 的 JButton。当用户按下按钮 b1 时，我希望 JFrame 窗口关闭。但不幸的是，我不知道该怎么做。请帮忙。下面是我的程序的 delivery() 方法：

public static void delivery()
{
    JFrame f = new JFrame("Name");
    f.setVisible(true);
    f.setSize(600,200);
    f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    f.setLocation(700,450);

    JPanel p = new JPanel();

    final JLabel l = new JLabel("Enter your name: ");

    final JTextField jt = new JTextField(20);

    JButton b1 = new JButton("Ok");
    b1.addActionListener(new ActionListener()
    {
        public void actionPerformed(ActionEvent e)
        {
            input = jt.getText();
        }
    });

    p.add(b1);
    p.add(l);
    p.add(jt);
    f.add(p);

    String b = JOptionPane.showInputDialog(null, "Please enter your address in one single line:");
    JOptionPane.showMessageDialog(null, "The ordered stuff will be delivered to " +input+ " who lives in: " +b , "Delivery" , JOptionPane.PLAIN_MESSAGE);
    JOptionPane.showMessageDialog(null, "Thank you for shopping at Paradise 24/7. Hope to see you again." , "Shopping Done!" , JOptionPane.PLAIN_MESSAGE);
}

使用JDialog代替JFrame弹出窗口
如果需要，使用setModal、ModalityTypes来防止Mouse和Keyboard事件JDialog
仅创建一个JDialog局部变量setDefaultCloseOperations(HIDE_ON_CLOSE)，然后您将在整个应用程序生命周期中使用setVisible(true/false)

setVisible() 应该为你解决问题

    public static void delivery()
{
    JFrame f = new JFrame("Name");
    f.setVisible(true);
    f.setSize(600,200);
    f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    f.setLocation(700,450);
    JPanel p = new JPanel();
    final JLabel l = new JLabel("Enter your name: ");
    final JTextField jt = new JTextField(20);
    JButton b1 = new JButton("Ok");
    b1.addActionListener(new ActionListener()
    {
        public void actionPerformed(ActionEvent e)
        {
            input = jt.getText();
            f.setVisible(false);
        }
    });
    p.add(b1);
    p.add(l);
    p.add(jt);
    f.add(p);
    String b = JOptionPane.showInputDialog(null, "Please enter your address in one single line:");
    JOptionPane.showMessageDialog(null, "The ordered stuff will be delivered to " +input+ " who lives in: " +b , "Delivery" , JOptionPane.PLAIN_MESSAGE);
    JOptionPane.showMessageDialog(null, "Thank you for shopping at Paradise 24/7. Hope to see you again." , "Shopping Done!" , JOptionPane.PLAIN_MESSAGE);
}

只需调用f.dispose()，以便您可以关闭 JFrame
