I have a second JPanel (Panel 2) that I am placing over another main JPanel (Panel 1). On the second panel I am adding another re-sizable panel (Panel 3). I am defining Panel 2 as JPanel Panel2 = new JPanel(null); I would like the background of Panel 2 to be transparent so I can see the content of Panel 1. I have tried Panel2.setOpaque(false) but this still doesnt make the background transparent. And suggestions on what is different? What exactly does JPanel(null) do? Thanks
