Java/Swing FAQ: How do I set the help text (i.e., help text, balloon text, tooltip text) on a JTextField?
Solution: Just call the setToolTipText
method on the JTextField. Here's a quick JTextField tooltip display example:
// create a textfield with tooltip help text JTextField textfield = new JTextField(10); textfield.setToolTipText("Enter your username over here, that other thing is a label.");
