My draggable class should help. Even if it's not exactly what your looking for you should be able to adapt it
you are welcome to use and modify this class but please do not change the package or take credit for it as your own work
Draggable.java
===========================
package tjacobs.ui;
import java.awt.Component;
import java.awt.Cursor;
import java.awt.Dimension;
import java.awt.Point;
import java.awt.Window;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionListener;
/** tjacobs.ui.Draggable
*  usage:
*                 Component c = ...
*                 new Draggable(c);
*                 parent.add(c);
public class Draggable extends MouseAdapter implements MouseMotionListener {
    Point mLastPoint;
    Component mDraggable;
    public Draggable(Component w) {
        w.addMouseMotionListener(this);
        w.addMouseListener(this);
        mDraggable = w;
     public Draggable(Window w, Component drag) {
          drag.addMouseMotionListener(this);
        drag.addMouseListener(this);
          mDraggable = w;
    public void mousePressed(MouseEvent me) {
          if (mDraggable.getCursor().equals(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR))) {
               mLastPoint = me.getPoint();
          else {
               mLastPoint = null;
     private void setCursorType(Point p) {
          Point loc = mDraggable.getLocation();
          Dimension size = mDraggable.getSize();
          if ((p.y + WindowUtilities.RESIZE_MARGIN_SIZE < loc.y + size.height) && (p.x + WindowUtilities.RESIZE_MARGIN_SIZE < p.x + size.width)) {
               mDraggable.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
    public void mouseReleased(MouseEvent me) {
        mLastPoint = null;
    public void mouseMoved(MouseEvent me) {
          setCursorType(me.getPoint());
    public void mouseDragged(MouseEvent me) {
        int x, y;
        if (mLastPoint != null) {
            x = mDraggable.getX() + (me.getX() - (int)mLastPoint.getX());
            y = mDraggable.getY() + (me.getY() - (int)mLastPoint.getY());
            mDraggable.setLocation(x, y);
