How to add a JSeparator beside a JLabel in a Jpanel?

Question

How do I add all of these component in a JPanel by using MigLayout and achieve the rest of the conditions as described in the above picture?

Answer 1

Using MigLayout you can simply add a JSeparator to the adjacent cell, giving it the growx property. For instance:

JLabel lblPersonal = new JLabel("Personal");
contentPane.add(lblPersonal, "cell 0 0");
contentPane.add(new JSeparator(), "cell 1 0,growx");

Or, perhaps a nicer way, is to use a border on a panel, while giving the panel a title as such:

import java.awt.*;
import javax.swing.*;
import javax.swing.border.*;
import net.miginfocom.swing.MigLayout;

public class TitledPanel extends JFrame {
    private static final long serialVersionUID = 1L;
    private JPanel contentPane;
    private JTextField textField;

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

    public TitledPanel() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);
        contentPane.setLayout(new MigLayout("", "[grow]", "[grow]"));

        JPanel panel = new JPanel();
        panel.setBorder(new TitledBorder(BorderFactory.createLineBorder(Color.LIGHT_GRAY), "Personal"));
        contentPane.add(panel, "cell 0 0,grow");

        JLabel lblLabel = new JLabel("Label 1");
        panel.add(lblLabel);

        textField = new JTextField();
        panel.add(textField);
        textField.setColumns(10);

        pack();
    }

}

Now, if you want to create a function that returns such panels when you pass a string parameter, you could extend a JPanel or create your own class that returns your custom-created JPanel with the given title label and separator.
