| + | Here is another incantation: | ||
| + | |||
| + | <pre> | ||
| + | // This program shows simple graphics in a window. | ||
| + | |||
| + | import java.awt.*; | ||
| + | import javax.swing.*; | ||
| + | |||
| + | public class HelloGraphics extends JPanel | ||
| + | { | ||
| + | public void paintComponent(Graphics g) | ||
| + | { | ||
| + | super.paintComponent(g); // Call JPanel's paintComponent method | ||
| + | // to paint the background | ||
| + | g.setColor(Color.RED); | ||
| + | |||
| + | // Draw a 150 by 45 rectangle with the upper-left | ||
| + | // corner at x = 25, y = 40: | ||
| + | g.drawRect(20, 40, 150, 45); | ||
| + | |||
| + | g.setColor(Color.BLUE); | ||
| + | |||
| + | // Draw a string of text starting at x = 60, y = 25: | ||
| + | g.drawString("Hello, Graphics!", 55, 65); | ||
| + | } | ||
| + | |||
| + | public static void main(String[] args) | ||
| + | { | ||
| + | JFrame window = new JFrame("Graphics Demo"); | ||
| + | // Set this window's location and size: | ||
| + | // upper-left corner at 300, 300; width 200, height 100 | ||
| + | window.setBounds(300, 300, 200, 150); | ||
| + | window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); | ||
| + | |||
| + | HelloGraphics panel = new HelloGraphics(); | ||
| + | panel.setBackground(Color.WHITE); // the default color is light gray | ||
| + | Container c = window.getContentPane(); | ||
| + | c.add(panel); | ||
| + | |||
| + | window.setVisible(true); | ||
| + | } | ||
| + | } | ||
| + | </pre> | ||
| + | |||
| + | This incantation has not followed the rules of the curly braces, but will still work. | ||
