Java 2D in the Real World

Yesterday we discussed the Java 2D API: how it works and how to use it. Today we're going to get our hands dirty with code as we study a real world application.

Java 2D in the Real World - The Entry Point
(Page 4 of 4 )


And the following is the entry point of the application:


package Kucchi;


import javax.swing.JFrame;

import java.awt.event.WindowAdapter;

import java.awt.event.WindowEvent;

import java.awt.Container;

import Kucchi.*;

import java.awt.BorderLayout;


public class Kucchi extends JFrame {



    /** Creates a new instance of Kucchi */

    public Kucchi() {

        setJMenuBar(new Kucchi_MenuBar());

        Container c = getContentPane();

        Kucchi_QuickBar q_bar = new Kucchi_QuickBar();




        Kucchi_PaintBar p_bar = new Kucchi_PaintBar();




        Kucchi_ColorBar c_bar = new Kucchi_ColorBar();












    private void initComponents() {

        addWindowListener(new WindowAdapter() {

            public void windowClosing(WindowEvent evt) {












    public static void main(String args[]) {

        int ToolNum;

        Kucchi K = new Kucchi();






That brings us to the end of this discussion. Many of the advanced aspects of the Java 2D API have been used in the above application. I will be discussing each of them one by one in upcoming articles starting with image manipulation in the next part. By the way, in Hindi "Kucchi" means "brush." Till thenů
