Java: Clicking inside a moved shape.

[spadewarrior]

Hello everyone. I've been trying to register when a point is inside of a Shape created from a GeneralPath in Java.

The problem I'm having is that I want to translate() my shape to arbitrary co-ordinates, but the shape still acts like it's in the top left of the screen (the original place of the GeneralPath).

Can anybody suggest a way of moving my shape to anywhere on my panel that moves the whole path as well?


Here is my code:


import java.awt.*;
import javax.swing.*;
import java.awt.geom.*;

/*
* Represents a Hexagon shape.
*/
public class Hexagon
{
private GeneralPath path;

AffineTransform aff;
private Double sideLength;
private double hexOffset;

private Shape hexShape;

/*
* Hexagon
*/
public Hexagon(Double size)
{
super();
sideLength = size;
setUp();

}

private void setUp()
{
hexOffset = sideLength * Math.sqrt(3);

path = new GeneralPath();
path.moveTo(1, 0);
path.setWindingRule(GeneralPath.WIND_EVEN_ODD);

for(int i = 1; i < 6; i++)
{
path.lineTo(Math.cos(i * Math.PI/3), Math.sin(i * Math.PI/3));
}

path.closePath();

aff = new AffineTransform();

aff.scale(sideLength, sideLength);
aff.rotate(Math.PI / 6);
hexShape = aff.createTransformedShape(path);

}

public GeneralPath getPath()
{
return path;
}

public Double getSize()
{
return sideLength;
}

public Shape getShape()
{
return hexShape;
}



}




import java.awt.*;
import javax.swing.*;
import java.awt.geom.*;
import java.awt.event.*;
/*
* Represents a Hexagon-shape panel.
*/
public class HexPanel extends JPanel
{
private final Hexagon hexagon;

public HexPanel(double hexSize)
{
super();
hexagon = new Hexagon(hexSize);
setMouseListener();
}

private void setMouseListener()
{
this.addMouseListener(
new MouseAdapter() {
public void mousePressed( MouseEvent e )
{
if(hexagon.getShape().contains(e.getPoint()))
{
System.out.println("mouse pressed inside hexagon");
}
repaint();
}

public void mouseReleased( MouseEvent e )
{


repaint();
}
}
);
}

public void paintComponent(Graphics g)
{
super.paintComponent(g);
Graphics2D g2 = (Graphics2D)g;
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASIN G,
RenderingHints.VALUE_ANTIALIAS_ON);

g2.setStroke(new BasicStroke(0.89f));
g2.setPaint(new Color(0, 0, 0));

g2.translate(200, 100);

g2.draw(hexagon.getShape());
}



public static void main(String[] args)
{

SwingUtilities.invokeLater(new Runnable()
{
public void run()
{

JFrame f = new JFrame("Hexagon");
Dimension d = new Dimension(800, 600);
f.setPreferredSize(d);
HexPanel panel = new HexPanel(60);
panel.setPreferredSize(d);
f.getContentPane().add(panel);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

f.pack();
f.setVisible(true);



}
});


}







}

Many thanks. :)
