Let's say I want to make the opacity of a JPanel %20 viewable? I don't mean setOpaque (draw or not draw) or setVisible (show or hide)... I mean make it see-through JPanel.. you know?
Is this possible?

If you have a custom panel and want the whole thing to be semi-transparent, I advise you to do override its method paintComponent like this :
@Override
protected void paintComponent(Graphics graphics) {
super.paintComponent(graphics);
Graphics2D g2d = (Graphics2D) graphics;
g2d.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.5f));
}
