Usage

From source file:TransferableScribblePane.java

public TransferableScribblePane() {
    setPreferredSize(new Dimension(450, 200)); // We need a default size
    setBorder(normalBorder); // and a border.
    lines = new ArrayList(); // Start with an empty list of lines

    // Register interest in mouse button and mouse motion events.
    enableEvents(AWTEvent.MOUSE_EVENT_MASK | AWTEvent.MOUSE_MOTION_EVENT_MASK);

    // Enable drag-and-drop by specifying a listener that will be
    // notified when a drag begins. dragGestureListener is defined later.
    DragSource dragSource = DragSource.getDefaultDragSource();
    dragSource.createDefaultDragGestureRecognizer(this, DnDConstants.ACTION_COPY_OR_MOVE, dragGestureListener);

    // Enable drops on this component by registering a listener to
    // be notified when something is dragged or dropped over us.
    this.setDropTarget(new DropTarget(this, dropTargetListener));

    // Check whether the system allows us to drag an image of the line
    canDragImage = dragSource.isDragImageSupported();
}

From source file:ScribbleDragAndDrop.java

    // Register listeners to handle drawing
    addMouseListener(this);

    // Create a DragSource and DragGestureRecognizer to listen for drags
    // The DragGestureRecognizer will notify the DragGestureListener

            DnDConstants.ACTION_COPY_OR_MOVE, // What drag types?
            this);// the listener

    // Create and set up a DropTarget that will listen for drags and
    // drops over this component, and will notify the DropTargetListener
    DropTarget dropTarget = new DropTarget(this, // component to monitor
            this); // listener to notify
    this.setDropTarget(dropTarget); // Tell the component about it.
