JColorChooser Component in Java

[boobies69]

Today, i will teach you how to create a program that has the JColorChooser component in Java. We have ColorDialog in VB.NET and C# and this is equivalent to the JColorChooser in Java.

So, now let's start this tutorial!

1. Open JCreator or NetBeans and make a java program with a file name of colorChooser.java.

2. Import java.awt.* and javax.swing.* packages because we will going to have the JColorChooser component in swing and also the JPanel as the container of this.

1. import
   
   javax.swing.*
   
   ;
   
2. import
   
   java.awt.*
   
   ;
   

3. Creates an instance of JColorChooser and set Color.RED as the default selected color and named it as jcc. This will be below in your public class colorChooser extends JFrame .

1. JColorChooser
   
   jcc =
   
   new
   
   JColorChooser
   
   (
   
   Color
   
   .RED
   
   )
   
   ;
   

4. Create a constructor that is the same with the filename and create a panel out of there to hold the JColorChooser and its border.

1. JPanel
   
   content =
   
   new
   
   JPanel
   
   (
   
   )
   
   ;
   
2. content.setLayout
   
   (
   
   new
   
   BorderLayout
   
   (
   
   )
   
   )
   
   ;
   
3. content.add
   
   (
   
   jcc, BorderLayout
   
   .CENTER
   
   )
   
   ;
   

Set window characteristics of the program. This will also add the panel and the jcolorchooser with its title and closing event.

1. this
   
   .setContentPane
   
   (
   
   content)
   
   ;
   
2. this
   
   .setTitle
   
   (
   
   "JColorChooser Component"
   
   )
   
   ;
   
3. this
   
   .setDefaultCloseOperation
   
   (
   
   JFrame
   
   .EXIT_ON_CLOSE
   
   )
   
   ;
   
4. this
   
   .pack
   
   (
   
   )
   
   ;
   

5. In your Main, create a JFrame component that will hold the panel and the JColorChooser component and all other components. This will set the visibility to True.

1. public
   
   static
   
   void
   
   main(
   
   String
   
   [
   
   ]
   
   args)
   
   {
   
2. JFrame
   
   chooser =
   
   new
   
   colorChooser(
   
   )
   
   ;
   
3. chooser.setVisible
   
   (
   
   true
   
   )
   
   ;
   
4. }
   

Press F5 and run the program.
