How do you set the actual content pane's background to be Opaque, the panels that I add to it I have already set Opaque but the tabbedpane main area keeps showing up as blue even when I do
JTabbedPane tabbedPane = new JTabbedPane();
If you add
UIManager.put("TabbedPane.contentOpaque", false); JTabbedPane tabbedPane = new JTabbedPane();
Then this solves the opacity problem.
