    Default Setting background color to translucent?!?!

    I'm trying to make all my panels translucent but cannot seem to make it work. I've made x1 blue and it worked as shown. I've looked up hints in my ide but it doesn't give me enough information.

    The last line of code below is not running correctly. I've looked up ways to do this but they are extremely extensive in code. I was hoping for a more condensed example on how to use it. Any ideas?

    JPanel x1 = new JPanel(new GridLayout(1,1));
            x1.setBackground(Color.decode("0x0000FF"));
            JPanel x2 = new JPanel(new GridLayout(1,1));
            x2.setBackground(Color.TRANSLUCENT);

    Why not just use setOpaque(false)?

    If you want help, you'll have to pose an SSCCE that demonstrates exactly what you're doing.

    I'm trying to create a GUI that looks like my terminal window you see in my attached screenshot. You can see that my terminal window is clear which brings a glassy look to the user. You can see stuff in the background in other words.

    Here is my code I have already. It contains a frame and a panel. I added a few other features which can be ignored for now. I tried doing the setOpaque(false) and I can see what it does but it's not giving me the functionality I'm looking for. Any ideas on how I could generate this glassy look.

    Setting a JPanel to be transparent or even non-opaque won't make the JFrame itself transparent.
