How do I save my JScrollPane position after I do a JFrame.pack()?

Question

I have the following code:

JFrame frame = new JFrame();
JScrollPane scrollPane = new JScrollPane(new panel(with stuff in it));
frame.getContentPane().add(scrollPane);

So the user scrolls a bit and then clicks a link on my panel and then I do a pack(), so I try the following code:

int val = scrollPane.getVerticalScrollBar().getValue();
frame.pack();
scrollPane.getVerticalScrollBar().setValue(val);

But this code still returns my scrollBar back to the beginning instead of keeping the position it was originally at before the pack. Any ideas would be appreciated, Thanks!

What does your `int val` hold? Is it the correct value? Does it work without a pack? — jzd, Jun 13 '11 at 20:07
@jzd : Yes val holds the correct value, and it does work without the pack. — Grammin, Jun 13 '11 at 20:09

just asking .. won't the frame.pack() will ignore the positioning of scrollBar — Abhishek Choudhary, Jun 14 '11 at 08:21

Try wrapping the setValue() method in a SwingUtilities.invokeLater().
