Urgent! JScrollPane for Window

Question

To use JScrollPane for a JTextArea, we usually will write as follow:
JTextArea text = new JTextArea (5,15);
JScrollPane scroll = new JScrollPane (text);
JPanel pane = new JPanel;
pane.add(scroll);
setContent(pane);
But if i want to add JScrollPane to a window, what should I write after
"JScrollPane scroll = new JScrollPane (.......)"?
and my this window is only to display a 2D graphic. So, I will have code as below,
GraphMsg graMsg = new GraphMsg();
          Container content = getContentPane();
          content.add(graMsg);
          JScrollPane scrollMsg = new JScrollPane(..............);
How should I add the JScrollPane to a JPanel?
Thanks...

Answer 1

Just add the panel to the JFrame... I assume that's what you mean by "window".
JTextArea text = new JTextArea (5,15);
JScrollPane scroll = new JScrollPane (text);
JPanel panel = new JPanel;
panel.add(scroll);
JFrame frame = new JFrame();
frame.getContentPane().setLayout(new BorderLayout());
frame.getContentPane().add(panel, BorderLayout.CENTER);
frame.pack();
frame.setVisible(true);
