Following example showcase how to create and use a Color Chooser in a dialog in swing based application.

We are using the following APIs.

• JColorChooser − To create a standard color chooser which allows user to choose colors from a pallete.

• JColorChooser.showDialog(); − To show the Color Chooser as a dialog box.

Example

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.LayoutManager;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JColorChooser;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;

public class SwingTester {
   public static void main(String[] args) {
      createWindow();
   }

   private static void createWindow() {    
      JFrame frame = new JFrame("Swing Tester");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      createUI(frame);
      frame.setSize(560, 400);      
      frame.setLocationRelativeTo(null);  
      frame.setVisible(true);
   }

   private static void createUI(final JFrame frame){  
      JPanel panel = new JPanel();
      LayoutManager layout = new FlowLayout();  
      panel.setLayout(layout);       
      final JLabel colorLabel = new JLabel("Color Chooser Example");
      JButton button = new JButton("Choose Color");

      button.addActionListener(new ActionListener() {
         @Override
         public void actionPerformed(ActionEvent e) {
            Color color = JColorChooser.showDialog(frame, 
               "Select Color of Label", Color.black);
      
            colorLabel.setForeground(color); 
         }
      });     
      panel.add(colorLabel);  
      panel.add(button);      
      frame.getContentPane().add(panel, BorderLayout.CENTER);    
   }  
}
