1: //RoundButton.java
  2: //Based on an example found on the Sun web site.

  4: import java.awt.*;
  5: import java.awt.geom.*;
  6: import javax.swing.*;

  8: public class RoundButton extends JButton
  9: {
 10:     public static void main(String[] args)
 11:     {
 12:         //Create a button with the label "Jackpot".
 13:         JButton button = new RoundButton("Jackpot");
 14:         button.setBackground(Color.green);

 16:         //Create a frame in which to show the button.
 17:         JFrame frame = new JFrame();
 18:         frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 19:         frame.getContentPane().setLayout(new FlowLayout());
 20:         frame.getContentPane().setBackground(Color.yellow);
 21:         frame.getContentPane().add(button);
 22:         frame.setSize(150, 120);
 23:         frame.setVisible(true);
 24:     }

 26:     public RoundButton(String label)
 27:     {
 28:         super(label);

 30:         //Enlarge button to make a circle rather than an oval.
 31:         Dimension size = getPreferredSize();
 32:         size.width = size.height = Math.max(size.width, size.height);
 33:         setPreferredSize(size);

 35:         //This call causes the JButton *not* to paint the background
 36:         //and allows us to paint a round background instead.
 37:         setContentAreaFilled(false);
 38:     }

 40:     //Paint the round background and label.
 41:     protected void paintComponent(Graphics g)
 42:     {
 43:         if (getModel().isArmed())
 44:             //You might want to make the highlight color
 45:             //a property of the RoundButton class.
 46:             g.setColor(Color.lightGray);
 47:         else
 48:             g.setColor(getBackground());
 49:         g.fillOval(0, 0, getSize().width-1, getSize().height-1);
 50:         //This call will paint label and focus rectangle.
 51:         super.paintComponent(g);
 52:     }

 54:     //Paint the border of the button using a simple stroke.
 55:     protected void paintBorder(Graphics g)
 56:     {
 57:         g.setColor(getForeground());
 58:         g.drawOval(0, 0, getSize().width-1, getSize().height-1);
