Is there a "Word Wrap" Property for JLabel?

When displaying dynamic text in a JLabel, automatically wrapping the text to the next line upon reaching the end of the screen can significantly improve readability. However, there is no direct "word wrap" property available for JLabel.

Solution:

To achieve automatic text wrapping, you can leverage CSS (Cascading Style Sheets) within your HTML tags. By setting the width of the text body using HTML styles, the JLabel will automatically determine the number of lines to render, thereby adjusting its preferred height. This approach avoids the complexities of calculating line breaks.

Implementation:

import javax.swing.*;

public class FixedWidthLabel {

    public static void main(String[] args) {
        final String longText = "Lorem ipsum dolor sit amet...";
        final String html = "<html><body>

Copy after login

In this code, by setting the width to 200px and 300px respectively, we demonstrate how the text will adjust its wrapping dynamically to fit within these widths.

Output:
