Serialize GeneralPath

I have changed the code below but I dont know why but I cannot access "Vector passedVPoints[ ]" (which is initiailsed in the constructor) in the paint method. Could anyone please tell me how I can do that then my problem will be solved?

Thanks a lot

class DrawPanel extends JPanel implements Serializable

{

Point from = new Point(), to = new Point(), origin = new Point();

Vector passedVPoints[] = new Vector[2];

DrawPanel(Vector[] vPoints)//index "0" denotes the x co-ordinate and "1" denotes y

{

origin.x = (Integer) Collections.min(vPoints[0]);

origin.y = (Integer) Collections.min(vPoints[1]);

passedVPoints = vPoints;

setSize((Integer) Collections.max(vPoints[0]),(Integer) Collections.max(vPoints[1]));//gets the max "x" and "y"

setLocation(origin); //The panel should reside here not from where the first click is

repaint(); //after the polypath is complete send it to the paintComponent for drawing it

}

public void paintComponent(Graphics g)//It reaches this part after getting out of the "mousePressed" event

{

setOpaque(true);

Graphics2D g2 = (Graphics2D) g;

g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);

//g2.draw(polyPath);

System.out.println(passedVPoints[0].size());

from.x =((Integer) passedVPoints[0].firstElement()) - origin.x;

from.y =((Integer) passedVPoints[1].firstElement()) - origin.y;

for(int i=1; i< passedVPoints[0].size(); i++)

{

to.x =( (Integer) passedVPoints[0].elementAt(i) ) - origin.x;

to.y =( (Integer) passedVPoints[1].elementAt(i) ) - origin.y;

g2.drawLine(from.x,from.y, to.x,to.y);

from.x = to.x;

from.y = to.y;

}

}

}

okay, find below the simpler code:

I just need a way to pass values into the paintComponent() method

Thanks
