How do I add a title to a border?

By Wayan in Swing 0 Comment

This example shows you how to create a border that have a title in it. There is a special border class the TitledBorder that does this. We can define the justification of the title, left, centered or right justify. To do this we call the setTitleJustification() method. We can also set other attributes such as font or the title position.

package org.kodejava.swing;

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

public class TitledBorderExample extends JFrame {
    public TitledBorderExample() {
        initializeUI();
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(
                () -> new TitledBorderExample().setVisible(true));
    }

    private void initializeUI() {
        setSize(500, 500);
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        setLayout(new FlowLayout(FlowLayout.LEFT));

        TitledBorder border = new TitledBorder(" Form Data ");
        border.setTitleJustification(TitledBorder.LEFT);
        border.setTitlePosition(TitledBorder.TOP);

        JPanel panel = new JPanel();
        panel.setBorder(border);
        panel.setLayout(new GridLayout(1, 2));

        JLabel usernameLabel = new JLabel("Username: ");
        JTextField usernameField = new JTextField();
        panel.add(usernameLabel);
        panel.add(usernameField);

        setContentPane(panel);
    }
}
