Set the Tooltip Delay Time for a Particular Component in Java Swing

Question

I'm trying to set tooltips on a JEditorPane. The method which I use to determine what tooltip text to show is fairly CPU intensive - and so I would like to only show it after the mouse has stopped for a short amount of time - say 1 second.

I know I can use ToolTipManager.sharedInstance().setInitialDelay(), however this will set the delay time for tooltips on all swing components at once and I don't want this.

If what you want is to make the tooltip dismiss delay much longer for a specific component, then this is a nice hack:

(kudos to tech at http://tech.chitgoks.com/2010/05/31/disable-tooltip-delay-in-java-swing/)

private final int defaultDismissTimeout = ToolTipManager.sharedInstance().getDismissDelay();

addMouseListener(new MouseAdapter() {

  public void mouseEntered(MouseEvent me) {
    ToolTipManager.sharedInstance().setDismissDelay(60000);
  }

  public void mouseExited(MouseEvent me) {
    ToolTipManager.sharedInstance().setDismissDelay(defaultDismissTimeout);
  }
});
