Making Scrollbars Appear

I have a KPanel class derived from JPanel. It is embedded in a JScrollPane.
Initially the panel is blank and does not require scrollbars. As information
is written to the panel, its size grows until scrollbars are required. I am
overriding getPreferredSize in KPanel. Whenever information is added to the
panel, I call repaint() on the JScrollPane, but this does not result in a
call to KPanel's getPreferredSize. If I manually resize the window,
getPreferredSize does get called and the scrollbars appear. How can I get
the scrollbars to appear programmatically?
