JTabbed Pane and Opaqueness ??????????????????

Question

Hi All,
I have developed an application in Swing that uses JTabbedPane.The tabbed pane(say tabbedpane X),has a panel which is in turn made from 2 panels,say panel A and panel B.
I want to display the space beween the 2 panels,A and B by using the SetOpaque method.But this is not working.!!!!!!!!!!!!!!!!
Could any one explain or send me a sample code of "how to introduce opaqueness between 2 Panels originating from JTabbedPane "
Many Thanks,
Sabriz

Answer 1

You want to display the space between the two panels like showing the cellspaceing in HTML? Is that correkt?
Opaque isn't the right way to show this.. Opaque just turns on/off drawing the background of Components
Try this ...
          JFrame frame = new JFrame();
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          JPanel p = new JPanel(new GridLayout(2,2,10,10));
          p.setBackground(Color.BLACK);
          for(int i=0; i<4; i++) {
               JPanel tmp = new JPanel();
               tmp.setBorder(new LineBorder(Color.RED));
               tmp.setBackground(Color.GRAY);
               p.add(tmp);
          frame.setContentPane(p);
          frame.setSize(200, 200);
          frame.setVisible(true);Martin
