e745. Creating a Multiline Label for a JButton Component

A button label can show simple HTML tags when surrounded by the tags <HTML> and </HTML>. This example shows how to create multiple lines by using the <BR> tag. See the javax.swing.text.html.HTML class documentation for a list of supported tags.

    String label = "<html>"+"This is a"+"<br>"+"swing button"+"</html>";
    
    // Create an action with the label
    Action action = new AbstractAction(label) {
        // This method is called when the button is pressed
        public void actionPerformed(ActionEvent evt) {
            // Perform action
        }
    };
    
    // Create the button
    JButton button = new JButton(action);

By default, the lines are left justified. This label text will center the lines:

    button.setText("<html><center>"+"This is a"+"<br>"+"swing button"+"</center></html>");

This label text italicizes the second line:

    button.setText("<html>"+"This is a"+"<br><i>"+"swing button"+"</i></html>");
