title: Text-mouseover popups over a Swing JTextArea?
body: <p>Is there anything out there that allows you to show a small text popup window (like a tooltip) over <em>individual words</em> or letters in a Swing JTextArea? (Or a JTextArea alternative with similar functionality.)</p>
  
  <p>What I need should behave like a tooltip, in other words only display the popup text after the mouse has hovered over the word for a second or two, and it would vanish automatically once the mouse moves away. Of course the tricky part here is that I want it at the character/word level within the text, not at the component level... any suggestions?</p>
