It seems that the JScrollPane is not dynamic in your program.
What's the layout manager that your JScrollPane parent container use?
Can you post some code?

I like these books:
1.Java Tutorial (Begin Swing)
2.Java look and feel guideline (Specification)
3.Java Performance Guide (Read n time)
4.Java Effective Programming (Read n++ time)

The problem is not in this method:
getPreferredScrollableViewportSize()

you should look the JScrollablePanel class or use the following method:
public boolean getScrollableTracksViewportWidth() {
return true;
}
public boolean getScrollableTracksViewportHeight() {
return true;
}

The DefaultTableModel in javax.swing.table package provides this feature.

Hi,Gregg
The layout manager included in the JDK have not provide such feature, you can take a look the JOptionPane UI class button layout and JFileChooser UI class button layout, but they are not good enough.
And I have notice the StringLayout have add some feature in Jdk1.5, maybe
add this feature.
You also take a look the jgoodies form layout, It have host in java.net, and free to use.
Our company have release a layout suite, and it's commercial.

You can overide the method:
JSlider.setValue(int)

The Frame can be maximum and minimum and dialog cannot, in office software, it cannot use multiple document interface, just open new frame for every file, in this case, you cannot use dialog.
In other case, use dialog is preferred.

table.setFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, null);
table.setFocusTraversalKeys(KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS,
null);
table.setFocusCycleRoot(false);

overide the methd:
paintComponent(Graphics g)
and set the border to null
setBorder(null)

The code have two problems:
1.You should not add the "upperPanel" to contentPane, and then add
it to JSplitPane, the Java GUI container only permit add component
to one container.
2.You should use setPreferredSize intead of setMinimumSize for the
"upperPanel".
change you code to:
upperPanel.setPreferredSize(new Dimension(300, 150));
and remove the code:
contentPane.add(upperPanel, BorderLayout.NORTH);

Use native methods.

If you use jdk1.5, you can use the MouseInfo object, for details, please visit:
http://java.sun.com/j2se/1.5.0/docs/api/java/awt/MouseInfo.html
Hope that helps!

Why not use the following code:
ImageIcon icon = new ImageIcon(file.toURL());
instead of your mass code:
String ImgName = file.getPath();
ImgName = file.toString();
ImgName = ImgName.replace('\\','/');
