DnD problem

[mix99]

Ho guys i want just your idea about the following problem:
i have a jlabel than implements a droptarget listener...it makes some operation when i drop an image inside(this image is dragged from another component)...
I would to limitate the drop area inside the component without(or with less) modify the droptarget method. I create a polygon inside jlabel and i would that droplistener calls drop methods only when mouse goes inside polygon area...any idea? Thx you in advance guys...

I made up a test app to find out.
Here's some of the drop target listener code.

class DropLabel extends JLabel {
    DropTarget dropTarget;
    DropTargetListener targetListener;
    int actions = DnDConstants.ACTION_COPY;
    Polygon polygon;

    public DropLabel(ImageIcon icon) {
        super(icon);
        targetListener = new TargetListener();
        // component, actions, DropTargetListener, accepting
        dropTarget = new DropTarget(this, actions, targetListener, true);
    }

    private class TargetListener implements DropTargetListener {
        ...
        public void dragOver(DropTargetDragEvent dtde) {
            Point loc = dtde.getLocation();
            // Drop point must be over polygon.
            if(!isDragOK(dtde) || !polygon.contains(loc)) {
                dtde.rejectDrag();
                return;
            }
            dtde.acceptDrag(dtde.getDropAction());
        }

        public void drop(DropTargetDropEvent dtde) {
            // Check for congruity of actions.
            ...

            // Recover image from transferable data.
            BufferedImage image = ...

            // Check drop location is over polygon.
            Point loc = dtde.getLocation();
            if(!polygon.contains(loc)) {
                dtde.dropComplete(false);
                return;
            }
            dtde.dropComplete(true);
            setIcon(new ImageIcon(image));
        }
        ...
    }
    ...
}
