JTextField是否具有getEditor（）方法？

Question

我正在尋找問題的答案，但沒有任何幫助。 這是我的代碼：

jtf = new JTextField(15);
jtf.getEditor().getEditorComponent().addKeyListener(new KeyAdapter() 
{
    public void keyPressed(KeyEvent evt)
    {
        if(evt.getKeyCode() == KeyEvent.VK_ENTER)
        {
            jb.doClick();
        }
    }
});

在JTextField或面板中按Enter鍵時，如何觸發JButton？

編輯：解決了！

private class ListenForButton implements ActionListener {
    public void actionPerformed(ActionEvent e) {
        Object source = e.getSource();
        if (source == jb2) {
            System.exit(0);
        } else if (source == jb) {
            ..
        } else { 
          ..
        }
        }
        catch (SQLException | HeadlessException a) {
            ..
        }
        } else if (source == jtf) // its work now
        {
            jb.doClick();
        }
    }

您能給我們更多背景嗎？

我嘗試在文本字段上添加Enter偵聽器，但似乎工作正常，這是我的代碼。

package com.apixandru.jvshot;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.WindowConstants;
import javax.swing.border.EmptyBorder;
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;

import static java.awt.BorderLayout.EAST;
import static javax.swing.JOptionPane.showMessageDialog;

    public static void main(String[] args) {

        JButton jb = new JButton("Search");
        jb.addActionListener((evt) -> showMessageDialog(null, "Button 'clicked'"));

        JTextField jtf = new JTextField(15);
        jtf.addKeyListener(new KeyAdapter() {
            public void keyPressed(KeyEvent evt) {
                if (evt.getKeyCode() == KeyEvent.VK_ENTER) {
                    jb.doClick();
                }
            }
        });

        JPanel panel = new JPanel(new BorderLayout());
        panel.add(jtf);
        panel.add(jb, EAST);
        panel.setBorder(new EmptyBorder(5, 5, 5, 5));

        JFrame frame = new JFrame();
        frame.setContentPane(panel);
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        frame.setLocationRelativeTo(null);
        frame.pack();
        frame.setVisible(true);

    }

}
