Question

How can I make the text of a JLabel extend onto another line?

Was it helpful?

Solution

You can do it by putting HTML in the code, so:

JFrame frame = new JFrame();
frame.setLayout(new GridLayout());
JLabel label = new JLabel("<html>First line<br>Second line</html>");
frame.add(label);
frame.pack();
frame.setVisible(true);

OTHER TIPS

if you want your jLabel Text to resize automaticly for example in a stretchable gridbaglayout its enough just to put its text in html tags like so:

JLabel label = new JLabel("<html>First line and maybe second line</html>");

Type the content (i.e., the "text" property field) inside a <html></html> tag. So you can use <br> or<P> to insert a newline.

For example:

String labelContent = "<html>Twinkle, twinkle, little star,<BR>How I wonder what you are.<BR>Up above the world so high,<BR>Like a diamond in the sky.</html>";

It will display as follows:

Twinkle, twinkle, little star,
How I wonder what you are.
Up above the world so high,
Like a diamond in the sky.

You can also use a JXLabel from the SwingX library.

JXLabel multiline = new JXLabel("this is a \nMultiline Text");
multiline.setLineWrap(true);

I have used JTextArea for multiline JLabels.

JTextArea textarea = new JTextArea ("1\n2\n3\n"+"4\n");

http://docs.oracle.com/javase/7/docs/api/javax/swing/JTextArea.html

In my case it was enough to split the text at every \n and then create a JLabel for every line:

JPanel panel = new JPanel(new GridLayout(0,1));
String[] lines = message.split("\n");
for (String line : lines) {
    JLabel label = new JLabel(line);
    panel.add(label);
}

I used above in a JOptionPane.showMessageDialog

It is possible to use (basic) CSS in the HTML.

This question was linked from Multiline JLabels - Java.

String labelText ="<html>Name :"+name+"<br>Surname :"+surname+"<br>Gender :"+gender+"</html>";
JLabel label=new JLabel(labelText);
label.setVisible(true);
label.setBounds(10, 10,300, 100);
dialog.add(label);

why you are giving complex things...you can just do it by putting "\n" instead of html tags
