Potrebna mi je jedna mala pomoc, treba da u ovom mouseDraged-u omogucim pomeranje ove elipse (odnosno kruga). Znam da me neka sitnica muci, pa ne mogu vise da se nerviram, pa ako mozete pomozite...Pozzz..

P.S. Ovaj JPanel je ubacen u neki GUI, ali to je naravno sada nebitno...

Code:

package domaci;

import java.awt.AlphaComposite;
import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.Composite;
import java.awt.GradientPaint;
import java.awt.Graphics;

import java.awt.RenderingHints;
import java.awt.Shape;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.geom.Ellipse2D;
import java.util.ArrayList;

import javax.swing.JPanel;

public class DrowPanel extends JPanel implements MouseListener {
    private Shape selectedShape;
    private ArrayList<Shape> shapes = new ArrayList<Shape>();
    private AlphaComposite transparency = AlphaComposite.getInstance(
            AlphaComposite.SRC_OVER, 0.3f);

    public void paint(Graphics g) {
        super.paint(g);
        Graphics2D g2d = (Graphics2D) g;
        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                RenderingHints.VALUE_ANTIALIAS_ON);
        for (Shape s : shapes) {
            GradientPaint gp = new GradientPaint(s.getBounds().x,
                    s.getBounds().y, Color.BLUE, s.getBounds().x,
                    getBounds().y, Color.BLACK);
            g2d.setPaint(gp);
            Composite orginalComposite = g2d.getComposite();
            if (s == selectedShape) {
                float[] dashPattent = { 30, 10, 10, 10 };
                g2d.setStroke(new BasicStroke(8, BasicStroke.CAP_BUTT,
                        BasicStroke.JOIN_MITER, 10, dashPattent, 0));
                g2d.setComposite(transparency);
            }

            g2d.fill(s);
            g2d.setPaint(Color.BLACK);
            g2d.draw(s);
            g2d.setStroke(new BasicStroke());
            g2d.setComposite(orginalComposite);

        }
}

    }

            Ellipse2D.Double el = new Ellipse2D.Double(e.getX() - 35,e.getY() - 35, 70, 70);
            shapes.add(el);
        }
        repaint();
    }

    @Override

        }

          }
