Hello,
you could use FileChooser's setControlButtonsAreShown(boolean)-method:import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import javax.swing.*;
import javax.swing.filechooser.FileSystemView;
public class FileChooserTest extends JFrame
     public FileChooserTest()
          super("File-Chooser Test");
          setDefaultCloseOperation(EXIT_ON_CLOSE);
          final JFileChooser fileChooser = new JFileChooser(FileSystemView.getFileSystemView());
          fileChooser.setControlButtonsAreShown(false);
          fileChooser.addActionListener(new ActionListener(){
               public void actionPerformed(ActionEvent e)
                    getContentPane().invalidate();
                    fileChooser.setControlButtonsAreShown(true);
                    getContentPane().validate();
                    getContentPane().repaint();
          getContentPane().add(fileChooser);
          pack();
          setLocationRelativeTo(null);
          setVisible(true);
     public static void main(String[] args)
          new FileChooserTest();
}regards,
