public abstract class MouseDragGestureRecognizer

extends DragGestureRecognizer

implements MouseListener, MouseMotionListener

This abstract subclass of DragGestureRecognizer defines a DragGestureRecognizer for mouse based gestures. Each platform will implement its own concrete subclass of this class, available via the Toolkit.createDragGestureRecognizer() method, to encapsulate the recognition of the platform dependent mouse gesture(s) that initiate a Drag and Drop operation.
