How to change the JFileChooser's color on the title?

Question

I have a open JFeileChooser and I don't know why but the color changed to green in the open dialog window.

Answer 1

you can have a limited color range like this
import javax.swing.*;
import java.awt.*;
class Testing
  public void buildGUI()
    JDialog.setDefaultLookAndFeelDecorated(true);
    JFrame f = new JFrame();
    f.setLocationRelativeTo(null);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JFileChooser  fc = new MyFileChooser(".");
    f.pack();
    f.setVisible(true);
    fc.showOpenDialog(f);
  class MyFileChooser extends JFileChooser
    public MyFileChooser(String currentDirectoryPath)
      super(currentDirectoryPath);
    protected JDialog createDialog(Component parent) throws HeadlessException
      JDialog myDialog = super.createDialog(parent);
      myDialog.getRootPane().setWindowDecorationStyle(JRootPane.PLAIN_DIALOG);
      return myDialog;
  public static void main(String[] args)
    SwingUtilities.invokeLater(new Runnable(){
      public void run(){
        new Testing().buildGUI();
