JLabel - Show longer text as multiple lines?
Question
So say I have a really long line that I want to display in a JLabel . How can I do it?
Currently, longer lines come up as this:
I have to resize the window to see the complete text.
How can I make it so that there's linebreaks when the text almost reaches the width of my JFrame ?
I'm not sure if any code is required here for you to answer this, but still:
my frame properties:
frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(new Dimension(450, 400));
frame.setLocation(new Point(400, 300));
frame.setLayout(new BorderLayout());
The label I want to modify:
question = new JLabel("Question:");
question.setFont(new Font("Serif", Font.BOLD, 15));
question.setHorizontalAlignment(JLabel.CENTER);
EDIT: More details:
I am reading lines from a file and then displaying them. The size of lines is not fixed, and so I do not know where to put <br> at.
EDIT 2:
I ended up using JTextArea .
private JTextArea textAreaProperties(JTextArea textArea) {
textArea.setEditable(false);
textArea.setCursor(null);
textArea.setOpaque(false);
textArea.setFocusable(false);
textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);
return textArea;
}

Just another example, showing that, with the right layout manager, text wrapped in HTML tags will automatically wrap to the available space...
public class TestHTMLLabel {
public static void main(String[] args) {
new TestHTMLLabel();
}
public TestHTMLLabel() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
}
StringBuilder sb = new StringBuilder(64);
sb.append("<html>I have something to say, it's beter to burn out then to fade away.").
append(" This is a very long String to see if you can wrap with in").
append("the available space</html>");
JLabel label = new JLabel(sb.toString());
JFrame frame = new JFrame("Test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(label);
frame.setSize(100, 100);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
}

Use HTML to display the text within the Label.
JLabel fancyLabel = new JLabel("<html>Punch Taskmaster</html>");
(Taskmaster-suggested example added in)

Format with HTML. Works great.
import javax.swing.*;
import java.awt.*;
public class Test {
public static void main(String[] args) {
final JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(new Dimension(450, 400));
frame.setLocation(new Point(400, 300));
frame.setLayout(new BorderLayout());
final JLabel question = new JLabel("<html>Question:<br>What is love?<br>Baby don't hurt me<br>Don't hurt me<br>No more</html>");
question.setFont(new Font("Serif", Font.BOLD, 15));
question.setHorizontalAlignment(JLabel.CENTER);
frame.add(question);
frame.setVisible(true);
}
}

Something like this. The answer give by rcook is very correct. Its just example to show how it can be done.
b1 = new JLabel("<html>Default Lable I have to resize the
<br/> window to see the complete text.</html>");
