Force a Java Tooltip to Appear

Question

Given a JTextField (or any JComponent for that matter), how would one go about forcing that component\'s designated tooltip to appear, without any

Answer 1

The only way (besides creating your own Tooltip window) I've found is to emmulate the CTRL+F1 keystroke on focus:

new FocusAdapter()
{
    @Override
    public void focusGained(FocusEvent e)
    {
        try
        {
            KeyEvent ke = new KeyEvent(e.getComponent(), KeyEvent.KEY_PRESSED,
                    System.currentTimeMillis(), InputEvent.CTRL_MASK,
                    KeyEvent.VK_F1, KeyEvent.CHAR_UNDEFINED);
            e.getComponent().dispatchEvent(ke);
        }
        catch (Throwable e1)
        {e1.printStackTrace();}
    }
}

Unfortunately, the tooltip will disappear as soon as you move your mouse (outside of the component) or after a delay (see ToolTipManager.setDismissDelay).
