Adjustable Panels In a Display using Java Swing

I have an application that uses Swing. The display I am working on, uses a Box with a Horizontal Layout as the top container. In it, are three other boxes (which actually contain the content). The appearance to the user is a window with three panes, arranged horizontally across the screen. What I want to do is give the user the ability to c开发者_运维知识库hange the pane sizes (the width of the panes). I tried putting the interior boxes in a JTable, that failed miserably. Any other ideas?

Thank you

Try using a nested JSplitPane.
