OK I finally know what I want now.

I have one class that extends JFrame and includes a variety of Swing
components, one of which is a JTextArea, another of which is a JPanel
containing an Image (maybe it's not necessary or desirable to load it
on to a JPanel - suggestions welcome).

However it is done though I need to maintain equality between the
image size and the JTextArea size (when the container frame is
expanded). I tried to do it by passing a Dimension parameter through
to a class that makes the JPanel. This didn't work and I think it's
because the program doesn't 'know' the size of the JTextArea before it
creates the image panel (it thinks that both height and width are 0).

Here's the code, any suggestions are welcome.

//Picture class - draws image of given size and puts it on to JPanel
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
import javax.swing.*;
import java.io.*;

public class Picture extends JPanel
{
private String fileName;
private Image myImage, myScaledImage;
private Dimension imgSize;

/** Creates a new instance of Picture */

public Picture(String file, Dimension size)
{
fileName=file;
myImage=new ImageIcon(fileName).getImage();
imgSize=size;
}

public void paint(Graphics g)
{
super.paintComponent(g);
if(fileName!=null)
{
int width, height;
if(imgSize.width==0 || imgSize.height==0)
{
width=200; height=200;
}
else
{
width=imgSize.width;
height=imgSize.height;
}

myScaledImage=myImage.getScaledInstance(width, height,
myImage.SCALE_SMOOTH);
g.drawImage(myScaledImage,0,0,this);
}
else
g.drawString("Image not available",60,90);
}

}

//this is the snippet of code from the class that builds the JFrame -
mid is a
//class variable
mid=new JPanel(new GridLayout(1,2,20,0));
mid.add(description);
picPanel=toCheck.getPicture(description.getSize());
mid.add(picPanel);

//the getPicture method refers to this one here
public JPanel getPicture(Dimension size)
{
Picture itemPic=new Picture(fileName, size);
return itemPic;
}

Once again, any comments are welcome, sorry for being such an
incompetant.
