Multi-line ToolTipText

By peter_budo on Dec 26th, 2008 10:44 pm

Sometimes one line of tool tip is not enough. You may want to try and play around with JToolTip, but if you in hurry this "little hack" can be handy.
With little of HTML plus CSS code you can work out various formats (font, colour, alignment, size etc.).

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

public class ModifyToolTip {

  public static void main(String args[]) {
    Runnable runner = new Runnable() {
      public void run() {
        JFrame frame = new JFrame("JToolTip Sample");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

		JPanel panel = new JPanel();
		
		JButton butt = new JButton("Hello, World");
        butt.setPreferredSize(new Dimension(120,55));
        butt.setToolTipText("<html><center><h1>Hello,</h1>"
        	+"<h2 style='color: red; font-style: italic;'>World</h2>"
        	+"<b>Modified<br/>ToolTipText</b></center>"
        	+"<br/>so simple.");
        panel.add(butt);
        frame.add(panel);        

        frame.setSize(300, 150);
        frame.setVisible(true);
      }
    };
    EventQueue.invokeLater(runner);
  }
}

The ability to use (limited) HTML comes from JLabel, which is used to render tooltips. Many other Swing components (eg JList) also use JLabels to display a line of content, so this technique can be used to format text in many Swing components.
