try this
import javax.swing.*;
import java.awt.*;
public class Frame extends JPanel
{
public Frame()
{
JFrame frame=new JFrame();
frame.add(this);
frame.setSize(640, 480);
frame.setDefaultCloseOperation(
JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
public void paint(Graphics g) {
Graphics2D g2=(Graphics2D)g;
g2.setColor(Color.WHITE);
g2.fillRect(0,0,getWidth(),getHeight());
g2.setColor(Color.BLACK);
g2.drawRect(100,100,200,200);
}
}
Look at
http://java.sun.com/javase/6/docs/api/
You can use all the methods from the Graphics and Graphics2D classes on g2.
To insert a clipart you can either do this
import java.io.*;
import javax.imageio.*;
and then
try {
image=ImageIO.read(new File("c:/image.jpg"));
} catch(Exception e) {
}
and
public void paint(Graphics g) {
g.drawImage(image,0,0,null);
}
or you do this
public Frame()
{
JFrame frame=new JFrame();
frame.add(new JLabel(new ImageIcon("c:/image.jpg")));
frame.pack();
frame.setDefaultCloseOperation(
JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
