Creating GridLines in Java Swing

[URLJones]

Hi. I've created an application using a JInternalFrame which sits on a JDesktopPane. Within the JInternalFrame, I have place a JScrollPane which holds a number of horizontaly thin panels 1200(width) x 30(height). What I'd like to do is place some vertical gridlines over these panels. What I have done so far is create a JPanel with vertical gridLines (using Java.awt.Graphics drawLine() method) and used this panel as a GlassPane for the JInternalFrame (ie, frame.setGlassPane(gridPanel); ). Now the problem is that when I resize the frame or minimize it, the gridLines dissappear. I used a ComponentListener for the window (for when you resize it) but it only "works" when the frame gets Maximized. When I say "works" I mean that the Gridline panel shows up, but it is opaque (so I can't see the panels in the scrollpane). oh, and yes, I have set the panel to opaque = false. So, right now I am stuck. I kinda need this application complete in about a week, and this is the only thing holding me back. I am contemplating using a JLayeredPane to overcome this, but I'm not sure if it will do what I want it to. Any help would be much appreciated.

Thanks,

create a single tile which can be repeatively covered the background of JInternalFrame

The JInterFrame in this example does not work for my JDK 1.4
