Tooltip Transparency

Hi

I'm trying to create a tooltip with semi-transparent background, so far i've tried changing the paint method by extending the TooltipUI class, but so far I haven't had much luck, the background color fades, but it does not show the background, i've been using this to set transparency:

publicvoid paint(Graphics g, JComponent c){

Composite compo= AlphaComposite.getInstance(AlphaComposite.SRC_ATOP,

.7f);

Graphics2D g2 = (Graphics2D)g;

g2.setComposite(compo);

g2.setColor(new Color(255,0,0));

g2.fillRect(0,0,c.getWidth(),c.getHeight());

}

Like i said, the color fades, but it does not show anything that's behind, any help on this would be appreciated
