If there is only one file that can possibly
be loaded, it is not a 'choice' of file.
Why not simply offer a JCheckBox in a
JOptionPane e.g. "Load Default Settings?",
and dispense with the file chooser
completely?

Why would you ant to do this?

Or else just set the FFileChooser to only accept directories.  That
would let the user choose a directory in which to read or write the
file, but not have control over the filename itself.

  chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);

Try this

((JTextComponent)((Container)((Container)((Container)((Container)getComponent(2)).getComponent(2))).getComponent(2)).getComponent(1)).setEnabled(false);

in constructor of an extension to the JFileChooser class.

It drills down into the component hierarchy of the JFileChooser class
and finds the JTextComponent associated with the File Name. I used jdb
(via Eclipse) to expose these compoents in the Swing classes. Of
course Sun may change the JFileChooser w.r.t. this component hierarchy
in the future, but it works as of JDK 1.6

I was about to comment that was very
fragile code, and ask..

..did it also work X-plat and X-plaf?

But I thought I'd do a quick test 'here'
before I commented.

<sscce>
import java.awt.*;
import javax.swing.*;
import javax.swing.text.*;

class FileChooserTextField extends JFileChooser {

  FileChooserTextField() {
    super();
    Component theComponent = ((JTextComponent)
      ((Container)((Container)((Container)((Container)
      getComponent(2)).
      getComponent(2))).
      getComponent(2)).
      getComponent(1));
    System.out.println(theComponent);
  }

  public static void main(String[] args) {
    System.out.println("java.version: " +
System.getProperty("java.version") );
    JFileChooser filechooser = new FileChooserTextField();
  }
}
</sscce>

<output>
java.version: 1.6.0
Exception in thread "main"
    java.lang.ArrayIndexOutOfBoundsException:
    No such child: 2
  at java.awt.Container.getComponent(Container.java:281)
  at FileChooserTextField.<init>(FileChooserTextField.java:9)
  at FileChooserTextField.main(FileChooserTextField.java:20)
Press any key to continue . . .
</output>

..so I'll simply ask, on which OS, under
which PLAF, (of Java 1.6) *does* that work?

Andrew, this is a very very very good point. Although, you can play the 
with knowledge of how the plaf was written at a certain point in time it 
may come back to bite you. Before you know it your code might be stuck 
in, for example, JDK 1.4 forever.

Cheers,

Dan Andrews

Sounds like you try to establish some kind of security feature by
restricting the file chooser. That won't work out.
