Add Custom Components to JFileChooser

Let me show you how to add custom components to JFileChooser in Swing. This is very easy and even you have a method for that. In this post, i will be showing you how to use that method to use your own components and enjoy! Here we go!






import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class CustomJFileChooser extends JFrame
{
private JButton jb;
private JFileChooser jf;
private JPanel jp;
private JLabel jl;

 public CustomJFileChooser()
 {
 createAndShowGUI();
 }
 
 private void createAndShowGUI()
 {
 
 // Set frame properties
 setTitle("Custom JFileChooser");
 setSize(400,400);
 setLayout(new FlowLayout());
 setLocationRelativeTo(null);
 setDefaultCloseOperation(EXIT_ON_CLOSE);
 setVisible(true);
 
 // Create JButton
 jb=new JButton("Open JFileChooser");
 
 // Add ActionListener to JButton
 jb.addActionListener(new ActionListener(){
  public void actionPerformed(ActionEvent ae)
  {
  // Create JFileChooser
  jf=new JFileChooser();

  // Create JPanel
  jp=new JPanel();
 
  // Create JLabel
  jl=new JLabel("I am a label on custom JFileChooser");
 
  // Add JLabel to the JPanel
  jp.add(jl); 

  // This is that method, do it before showOpenDialog!
  jf.setAccessory(jp);
  
  // Show Open Dialog
  jf.showOpenDialog(null);
}
 });
 
 // Add JButton to the JFrame
 add(jb);
 }
 
 public static void main(String args[])
 {
 new CustomJFileChooser();
 }
}

Adding Custom Components to JFileChooser

This is not a hack, it is just a feature provided. This is the way you can add your own custom components to JFileChooser. You don't actually need the JPanel, I just added it, you can directly add JLabel to it. But in order to have a layout of the components we added i added JPanel. Good to know if we can add components in a certain layout to the JFileChooser without JPanel and without disturbing the layout of the JFileChooser's by-birth components.
