Fill a GeneralPath in Java

Description

The following code shows how to fill a GeneralPath.

Example


import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.geom.GeneralPath;
/*from w  w w  .  j a v a2 s.  c  o  m*/
import javax.swing.JComponent;
import javax.swing.JFrame;

class MyCanvas extends JComponent {
  public void paint(Graphics g) {
    Graphics2D g2 = (Graphics2D) g;
    g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
        RenderingHints.VALUE_ANTIALIAS_ON);

    g2.setPaint(Color.gray);
    int x = 5;
    int y = 7;

    int xPoints[] = { x, 200, x, 200 };
    int yPoints[] = { y, 230, 200, y };
    GeneralPath polygon = new GeneralPath(GeneralPath.WIND_EVEN_ODD,
        xPoints.length);
    polygon.moveTo(xPoints[0], yPoints[0]);
    for (int index = 1; index < xPoints.length; index++) {
      polygon.lineTo(xPoints[index], yPoints[index]);
    }
    polygon.closePath();

    g2.fill(polygon);
  }
}

public class Main {
  public static void main(String[] a) {
    JFrame window = new JFrame();
    window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    window.setBounds(30, 30, 450, 450);
    window.getContentPane().add(new MyCanvas());
    window.setVisible(true);
  }
}

The code above generates the following result.
