Transparent JFrame background

Question

Is it possible to make a JFrame that has a transparent background and draw an image on it, so only the image will be visible with no border or background?

Answer 1

You should make content pane transparent too.

frame.setUndecorated(true);
frame.getContentPane().setBackground(new Color(1.0f,1.0f,1.0f,0.0f));
frame.setBackground(new Color(1.0f,1.0f,1.0f,0.0f));
