Hi I have this program that creates a custom shape for a JButton, right now its just a rectangle, The question is can anyone help me with the math that will make the rectangle look like a diamond that looks tilted to make it look as if it is in an XYZ plane. Thanks in advance!!!
Here's program:
java
import java.awt.*;
import java.awt.geom.*;
import javax.swing.*;
import java.awt.Polygon.*;
public class RoundButton extends JButton
{
public RoundButton(String label)
{
super(label);
Dimension size = getPreferredSize();
size.width = size.height = Math.max(size.width, size.height);
setPreferredSize(size);
setContentAreaFilled(false);
}
protected void paintComponent(Graphics g)
{
if(getModel().isArmed())
{
g.setColor(Color.lightGray);
}
else
{
g.setColor(getBackground());
}
g.fillRect(0,0,getSize().width - 1, getSize().height - 1);
super.paintComponent(g);
}
protected void paintBorder(Graphics g)
{
g.setColor(getForeground());
g.drawRect(0,0,getSize().width-1, getSize().height-1);
}
Shape shape;
public boolean contains(int x, int y)
{
if(shape == null || !shape.getBounds().equals(getBounds()))
{
shape = new Ellipse2D.Float(0,0,getWidth(), getHeight());
}
return shape.contains(x, y);
}
public static void main(String[] args)
{
JButton button = new RoundButton("Jackpot");
button.setBackground(Color.green);
JFrame frame = new JFrame();
frame.getContentPane().setBackground(Color.yellow);
frame.getContentPane().add(button);
frame.getContentPane().setLayout(new FlowLayout());
frame.setSize(150, 150);
frame.setVisible(true);
}
}
