java - JButton 退出 JPanel

Question

我有多个取消、确定和保存按钮。当用户单击其中一个按钮时，我需要它退出 JPanel，而不是整个程序。我已经尝试了多次，我所做的一切都会退出整个程序。我的代码如下。我知道我的代码中有很多东西，可能会让人感到困惑。提前致谢。

Answer 1

我已经尝试了多次，我所做的一切都会退出整个程序。

我没有看到您关闭对话框的代码，所以我无法猜测您可能做错了什么。

在您的 ActionListener 中，您将调用对话框上的 dispose 方法。代码将类似于：

JButton button = (JButton)event.getSource();
Window dialog = SwingUtilities.windowForComponent( button );
dialog.dispose();

另一种方法可能是使用 JOptionPane，然后您不需要编写自己的 ActionListener。您可以轻松地将面板添加到选项窗格。下面的代码显示了两种方法：

import java.awt.*;
import javax.swing.*;

public class OptionPanePanel
{
    private static void createAndShowUI()
    {
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLocationRelativeTo( null );
        frame.setVisible( true );

        //  Build a custom panel

        JPanel panel = new JPanel( new GridLayout(2, 2) );
        panel.add( new JLabel("First Name") );
        JTextField firstName = new JTextField(10);
//      firstName.addAncestorListener( new RequestFocusListener(false) );
        panel.add( firstName );
        panel.add( new JLabel("Last Name") );
        JTextField lastName = new JTextField(10);
        panel.add( lastName );

        int result = JOptionPane.showConfirmDialog(
            null, // use your JFrame here
            panel,
            "Enter Name",
            JOptionPane.YES_NO_OPTION,
            JOptionPane.PLAIN_MESSAGE);

        if(result == JOptionPane.YES_OPTION)
        {
            System.out.println(firstName.getText() + " : " + lastName.getText());
        }
        else
        {
            System.out.println("Canceled");
        }

        //  Let Option Pane build the panel for you

        Object[] msg = {"First Name:", firstName, "Last Name:", lastName};

        result = JOptionPane.showConfirmDialog(
            frame,
            msg,
            "Enter Name...",
            JOptionPane.OK_CANCEL_OPTION,
            JOptionPane.PLAIN_MESSAGE);

        if (result == JOptionPane.YES_OPTION)
        {
            System.out.println(firstName.getText() + " : " + lastName.getText());
        }
        else
        {
            System.out.println("Canceled");
        }
    }

    public static void main(String[] args)
    {
        EventQueue.invokeLater(new Runnable()
        {
            public void run()
            {
                createAndShowUI();
            }
        });
    }
}

这种方法的一个问题是焦点将在确定按钮而不是文本字段上。要解决这个问题，您可以使用RequestFocusListenerDialog Focus中的内容。
