From source file:ColorDrag.java

public static void main(String args[]) {
    // Create two JLabel objects
    final JLabel label1 = new JLabel("Drag here");
    JLabel label2 = new JLabel("Drop here");

    // Register TransferHandler objects on them: label1 transfers its
    // foreground color and label2 transfers its background color.
    label1.setTransferHandler(new TransferHandler("foreground"));
    label2.setTransferHandler(new TransferHandler("background"));

    // Give label1 a foreground color other than the default
    // Make label2 opaque so it displays its background color
    label1.setForeground(new Color(100, 100, 200));
    label2.setOpaque(true);//from   w  ww . ja v  a  2s .c o m

    // Now look for drag gestures over label1. When one occurs,
    // tell the TransferHandler to begin a drag.
    // Exercise: modify this gesture recognition so that the drag doesn't
    // begin until the mouse has moved 4 pixels. This helps to keep
    // drags distinct from sloppy clicks. To do this, you'll need both
    // a MouseListener and a MouseMotionListener.
    label1.addMouseMotionListener(new MouseMotionAdapter() {
        public void mouseDragged(MouseEvent e) {
            TransferHandler handler = label1.getTransferHandler();
            handler.exportAsDrag(label1, e, TransferHandler.COPY);
        }
    });

    // Create a window, add the labels, and make it all visible.
    JFrame f = new JFrame("ColorDrag");
    f.getContentPane().setLayout(new FlowLayout());
    f.getContentPane().add(label1);
    f.getContentPane().add(label2);
