I have redone a few things and decided to change up the way the panel I was having problems with was displayed. Now it pops up in a new JFrame, but I am having problems here as well. The graphics aren't displaying quite correctly and when I resize it everything disappears. Here is the code:

Code:

import javax.swing.*;
import java.awt.*;
import java.awt.geom.*;
import javax.swing.border.*;
import java.awt.event.*;

public class seqDisplayFrame extends JFrame
{
	private interactiveRectangle iRect;
	private seqDisplayFrame sdFrame;
	
	public seqDisplayFrame(interactiveRectangle iR)
	{
		sdFrame = this;
		iRect = iR;
		sdFrame.setTitle(iRect.getContigName());
		
		seqDisplayPanel sdPanel = new seqDisplayPanel(iRect);
		sdFrame.add(sdPanel);
		sdFrame.pack();		
	}
	
	private class seqDisplayPanel extends JPanel
	{
		private interactiveRectangle intRect;
		private int paintY = 20;
	
		public seqDisplayPanel(interactiveRectangle iR)
		{
			intRect = iR;
			setPreferredSize(new Dimension(500,500));
			setBackground(Color.WHITE);
		}
		
		public void paintComponent(Graphics g)
		{
			super.paintComponent(g);
			Graphics2D g2 = (Graphics2D)g;
		
			String tempString = intRect.getContigSeq();
			int xDistance = 20;
			for(int i = 0; i < tempString.length(); i++)
			{
				if(i < (intRect.getStartOfUsedRegion() -1) || i > (intRect.getEndOfUsedRegion()-1))
					g2.setColor(Color.BLACK);
				else
					g2.setColor(Color.RED);
						
				g2.drawString(String.valueOf(tempString.charAt(i)), xDistance, paintY);
					xDistance += 8;
				if(xDistance > 480)
				{
					xDistance = 20;
					paintY += 15;
				}
			}
				
			g2.setColor(Color.BLACK);
			paintY +=20;
			String totalLength = ("The total length is: " + String.valueOf(intRect.getTotalLength()));
			g2.drawString(totalLength, 20, paintY);	
		}
	}
}
